A Photo and a few Words?
Would you like your car to appear, with you included, in the PCGB Porsche Post magazine Register column? Just provide a picture and some accompanying words about your car, where/why you bought it, any special connected story, and your passion for the marque and model; up to 400 or so words; forward it to us:

AGM
Don't forget you have the opportunity to attend your Club's AGM. Attend, and get to know the members running and volunteering to run your Club, it might inspire you to get involved yourself! If you are attending the AGM in person remember to take your Membership card along to join the meeting. Tea, coffee, sandwiches and cake are usually laid on! If you are a couple, how about Joint Membership, and you can both take part. On the Membership renewal page click membership type and apply for Joint at £80 withan initial joining fee of £10, rather than £75 individual membership, overseas is an additional £15 (price given as of 2023, plus a discount of £5 per annum is applied if you renew by Direct Debit) Membership details

There are many local Region and Clubhouse led events planned each year for the many thousands of Club members. The Club is the biggest in the UK and Europe, and the third biggest in the world, outside the USA and China. However, Porsche Club of America is based on a different format to PCGB, and I guess China don't have a notable heritage element yet. Both countries have a significantly larger market so we are doing well!

Front wheel/hub/brakes - moaning
At low speed this can sometimes be heard from the front hubs. It is thought to be the brake pads naturally rubbing lightly against the disks and disappears as speed picks up, this is not a problem. It may be worth checking that the caliper piston seals are still in good condition. I suggest using a specialist or competent maintainer to check the pistons move as intended

Buying a car
If you have narrowed down your choice to a car you want to buy, I would always suggest having a professional pre-purchase inspection.

If you haven't got behind the wheel of one yet:
     Compared to most modern vehicles with light controls; be prepared for heavier brakes, clutch and steering. Some find it a bit quirky eg, the pedals hinge from the floor. It feels natural enough to me.
     The benefit of the 'control' factors provide an engaging drive with so much more feel and feedback, even if your first impression is of the steering being 'lively' over road imperfections, the handling on banked corners will be rewarding.
     Be warned, the car will grow on you and is most likely to become part of the family

C-16 vehicle option code
This is the UK spec and comes with many 'standard' items that a non C-16 car may not have, from underseal to sunroof. The C-16 code will be shown in the vehicle option code list under the luggage lid, or in the front of the service handbook. A C-16 designated car may not necessarily have been supplied from a UK Porsche dealer; the car may have been collected direct from the factory or, from elsewhere like the Isle of Man etc.


Certificate of Production, formally Authenticity (CoP, CoA)
Porsche have withdrawn this, late 2018, after having already extending it for an extra year at the request of the Club. They explain they cannot continue with the provision of the certificate due to GDPR, General Data Protection Regulation, Compliance. My understanding is that it has been wirthdrawn worldwide.
There is a cost option available, Porsche Classic Technical Certificate - see T
Jan19: CoP Extract from the "Update" email from PCGB chairman:
"As many of you will be aware, the Certificate of Production from Porsche Cars Great Britain ceased in December. This was a popular and long-standing member benefit which the Club worked hard to try and retain. A combination of GDPR, legal concerns and a change in management at Porsche meant that ultimately it wasn’t possible for the member benefit to continue. Porsche will be launching a product to replace the CoP, but in no way will it be linked to the previous offering."

DME Relay

I fitted an OEM replacement part shortly after I bought the car, and kept the original in the car as a spare. A good idea that many owners follow. The relay is a known area of failure and swapping out with a handy spare is a good idea to get you on your way again. The fault is that the petrol pump won't run, the relay can fail whilst out driving so you coast to a stop. Find the relay under the passenger seat (RHD cars). As an example only, here is a selection of DME relays available from Type911. I have no affiliation to them, and don't think I bought my replacement there. I have used this as a comparison as they offer a 'budget', 'OEM', and 'Original' option. I would be drawn to an OEM part at £28+vat +p&p as my choice. Cost at March 2019

G Series
911 Carrera 3.2 variant is part of the G Series ('Series' refers to the production models).

Green Card
Green Card - the 'International Motor Insurance Card'; before setting off for Europe in early May I requested Lockton provide us with a copy. Earlier in the year they had advised on having a Green Card if we left the EU on 29 March but were not keen to provide me with one as it was after that date. They seemed to think we wouldn't leave until 31 October. I didn't want to be stranded in Europe without cover if we were to leave the union in a hurry before that date, there was talk we may exit on May 22, a few days before our return from Europe on May 25. At my second attempt Lockton issued the Green Card. To my surprise it is printed on green paper; I thought by now the 'green' reference would be a historic reference like the term MoT has become.
I had mentioned to Lockton that there is a 'Foreign Travel' statement on the back of the Certificate of Motor Insurance document that Lockton forwarded from Chubb after my annual renewal. This states the cover includes what they term as an 'insurance extended' facility that exists for the EU, and covers the usual additional countries like Switzerland, Iceland, Channel Islands etc. Lockton didn't respond to this so I assume if we left the EU this would no longer be valid, I thought that a little strange but they must know what is legal and appropriate.

Headlights
Consider using a relay kit (like the J West Engineering kit from the USA). Or, fitting your own relays to increase brightness and relieve the headlight switch and stalk contacts from switching the higher current.

Headlight Resilvering - tip from Charles Marsland
"Strip down the headlight (measure the adjusting screws to aid re-assembly) and send the reflector for re-silvering to Ashford Chroming £95" (£95 back in April 2013). 
Here Full link: http://www.ashfordchroming.com/headlamp-reflector-re-silvering-restoration
from home site here. Full link: www.ashfordchroming.com
April 2019 feedback from a Register customer: The whole headlamp shell was chromed, including a few clips that were sent along with it. Price was still as of 2013. The chrome layer where the lamp fits back meant a bit of filing was requited to refit the bulb but the job was well done. Tip, record the dismantling process in detail as fitting back together was a fiddle

International Driving Permit/s​ - IDP
The International Driving Permit/s; required to supplement your UK driving licence when driving abroad after the UK leaves the EU. When we went to Spain a few years ago we needed one of these, but that version doesn't cover all the other countries we were visiting in another year.

Engine Oil
It was thought the most suitable grade to use is a semi synthetic 10W/40. However, in 2018 I have moved to 20W/50. I found an unexpected benefit that the oil consumption on our European holidays was reduced.
Porsche now offer 10W/60 oil for classics

Engine Oil level checking
Engine idling on flat ground, oil hot, using dip stick - note; the tickover won't be so smooth with the oil cap off the filler neck. For the inexperienced... I've noticed on my car that as the temperature gauge needle on the dash rises, the needle on the oil level rises at the same rate on its gauge so, when topping up I have them balanced with one another. Be careful not to add too much oil. Leave room for the coefficient of thermal expansion of the oil (through high summer temperatures or from long runs or both!). Take care not to drop the dip stick in to the tank and don't let loose clothing get tangled in the fan belt!

Engine Oil Cooling
Oil temperature is controlled by a thermostat on the crankcase where the Engine fan airflow also cools oil through the engine mounted matrix cooler. When additional cooling is required a second thermostat in the rear wheelarch allows oil to flow to the front oil cooler.
The UK cars do not usually have a fan fitted to the front oil cooler, where US cars may

Transmission/Transaxle (Gearbox) Oil
I have heard (back in 2015 ish) that the use of SWEPCO gear oil is not recommended for use in the G50 gearbox, however, it is good for use in the 915 gearbox MY'84 - 86. Check the grade with your Porsche specialist or supplier, perhaps SWE-201-80W90.
For the G50 MY'87 - 89 an independent Porsche specialist recommended I use fully synthetic 75W/90 gear oil. It seems SWEPCO isn"t compatible with the syncro rings. Having now tried fully synthetic I thing I'll drop back to semi-synthetic at the next change.

Officials Conference
In April and November there is a meeting between the Club Directors and the Regional and Register Officials. If you wan't anything raised at these meetings please get in contact, in good time to allow the question to be submitted, and I'll endeavour to get you a reply.

Parts (Porsche supplied; general)
Porsche Centre parts aren't all necessarily prohibitively expensive, some item prices may surprise you (nicely), and remember the PCs often give PCGB Club members a discount. Why buy elsewhere when, for example, fan belts and oil filters can be bought at good prices, and this is not limited to small consumables either. Some non-Porsche oil filters can produce gurgling noises!

Porsche company crest
The crest, or shield, came about as a request from the US importer in 1952. The design is an amalgamation of the coat of arms from the local state of Wurttenberg and in the centre the coat of arms of the city of Stuttgart. There is a link between choosing the horse in the centre and a connection with the Ferrari family. Over time ther have been minor changes to the gold-plated galvinised and enamelled crest. (Oct19 on viewing the Porsche site some crests are incorrect!)

Iridium spark plugs, NGK BR8EIX, were recommended to me by an independent specialist. They have something like a 50,000-mile life and I've run a set for a number of years now and they have performed well.

Porsche Classic Technical Certificate:
A cost option that replaces the Certificate of Production, perhaps? More comprehensive, but more expensive too, at €499.00 incl VAT (In Euros as taken from a Porsche AG site) [Dec23]. If you like the idea get along to your nearest Classic Porsche Centre
* to have the car inspected for a certificate, see: 
https://www.porsche.com/germany/accessoriesandservices/classic/classic-partner/technicalcertificate/
Note: The Service Advisor at PC Swindon emaied to say this certificate isn't available in the UK (Dec23), although the Porsche website does not state this
UK accredited Classic PC's are: Bournemouth, Glasgow, Hatfield, Leeds and Swindon.

Transmission/Transaxle
1984 - 1986 Type 915 Incorporating an external oil cooler (Cable operated clutch)
1987 - 1989 Type G50 Produced by Getrag (Hydraulically operated clutch)

​Transmission chattering type buzz from G50 gearbox
Pulling away and at low revs the gearbox can emit this noise, most commonly heard in second gear. As the revs rise the sound disappears. It is suggested it is the gears chattering on their shaft. If it has been a while since a gearbox service an oil change can help reduce the noise. Please don't use Swepco in a G50 'box, however, it is good for use in the 915

Due to a piece in the Porsche Post modified column Aug20 p105 I asked Ian of Porsche Shop about fitting a G50 to a 915 car, as I have had some enquiries in the past. Here is his reply in full:

Hi Steve, thank you for your question. Its not really practical to convert a pre 1986 car to G50 because the gearbox is 6" longer than a 915 so Porsche had to split the torsion bar tube to allow the box to fit between the tubes, hence the Torsion bars on a G50 car stick out 8" eather side under the arch.

Ruff, Techart and some US vendors offered a "shorter 5th/reverse tail housing to enable a retro fit but I have no knowlege or 1st hand experiance of these but it can be done that way if needs be?

The hydraulics and clutch are not an issue but the bigger, heavier box is and they bring around £5k for a good one these days now so.......
Thank you Ian - I assume the flywheel, clutch and hydraulics are all accomodated and the use of uprated torsion bars and anti roll bars etc. for the weight gain can be substituted.

Why N Homologation Tyres?
Perhaps also known as: Original Equipment / Manufacturer Code / Tyre Approval
Abbreviated text from Michelin...
Extract... Porsche first to introduce a specific quality seal for tyres... N0 - N6 exist (2018) relates to the tyres technical spec at the time of its approval, and is continued sequentially. ...the N-marking stands out in particular due to their geometry. ...the rubber compound used and test procedure employed, which incorporates 33 key criteria in total. These include 12 objective outdoor criteria, such as dry and wet performance and service life. There are also 16 objective indoor criteria, rolling resistance and high speeds. In addition, the test also includes five subjective outdoor criteria, handling and comfort. Porsche makes no compromises when it comes to safety, and places greater value on traction - both on dry and wet road surfaces - than on fuel efficiency in its tyre tests. No matter how tempting it may be to purchase a tyre with optimised rolling resistance - in an emergency situation, every metre of braking distance counts. Only tyres with the N-marking provide you with the certainty that you are purchasing a high-quality tyre which has been specially tested for your model of Porsche

https://www.porscheclubgb.com/membership/valuations
I used the service for the first time in 2020. Having taken the speciffically required photos for the application on the same day I had the valuation back within the perscribed timescale.
For a price guide try here. Full link: http://apps.hagerty.com/ukvaluation/index.html
The last time I viewed the site the values were the same across all years of the model. You may have to adjust for Sport/non-Sport and vehicle modifications, options and history. Bear in mind these may be considered as replacement costs

Wheels
Wheel Centre Crested Caps
The one about the point of the Stuttgart crest pointing to the tyre valve.
A couple of years ago (2016) I was talking to a Hatfield PC workshop technician that was just back from a 'classic' training course at the Factory. The lead tutor was an elderly chap from back in the early years, he spoke about the wheel centre factory 'rule' to the candidates. He explained it was set up by the Factory. I was interested to hear this as I thought it was a Club thing.

It is generally agreed the standard 15" or 16" wheels handle better than fitting later larger diameter wheels

Windscreen Leak / Fitting
Can be helped by replacing the windscreen rubber, I was advised to use an OEM or genuine Porsche replacement on my '89 (1989 body shell had a 10mm larger size window aperture and glass to earlier years, as on the 964 model). No more leaks.
It is worth checking beforehand that the 'fitter' has experience with the old style cord technique for fitting glass. This method is a bit of a dying art for the mainstream companies

Rear Wing and Chin Spoiler
Generally referred to as the 'whale tail' was designed to replace the earlier 'duck tail'. One reason I read was that it was on safety grounds after a motorcyclist was fatally injured in an autobahn accident. The 'tea tray', with turned up sides, is fitted to the turbo models.
The fitting of the spoilers at both ends reduced drag and lift - the rear wing increases straight line stability at speed.
SAFETY NOTICE: If the rear wing is removed the front chin spoiler should also be removed. Only removing the rear wing is more likely to induce oversteer, or conversely no chin spoiler with rear wing may induce understeer. They were designed to be used as a pair for a reason, handling balance!

Wiper Arm Replacement
The original 3.2 type replacement arms are no longer available. The replacements are now the 964 twin spring type (RHD Right:
964 628 028 01 Left: 964 628 028 03 or LHD Right: 964 628 028 02 Left: 964 628 028 01 - check part numbers before ordering!)They are broader at the spring end, as you may expect, and also need to have the larger appropriate fixing nut cover for the new arms (x2 928 628 623 01 - check part number before ordering!). When looking into the fixing hole they do not appear to have the required splines to fit the splined mounting shaft. The centre is made of soft pot metal and will form splines as the arm is tightened, by the nut, onto the splined shaft.

Well I wasn't expecting to have a 'Z', until Zoom came along!
Back in April 2020 using Zoom video meeting was a Club initiative so Register and Region Officials could keep in contact with Club members. The tool allows members to enjoy the company of some like minded company during the Covid-19 pandemic. Sue and I took up the offer of a Club sponsered Zoom Pro acccount and we set about keeping in touch with Register members.
