Ever wish you'd never bothered....

Well, last night having finally got all the bits I need and some time I decided to start the rebuild of the belts/ front oil seal etc.

Being new to the job thought I'd try and get a reference point for the oil pump sleeve - ie line it up in the pump splines then mark it with a pen relative to the woodruff key hole, pull it out then fit the oil seal.

Anyhow, 3 hours later I finally managed to remove both the butchered oil seal and stuck on oil sleeve...... In short 3hours of huffing and puffing and now need to buy two new components !

At one point I really thought I was going to have to dismantle the front of the engine to remove the oil pump......

Hey ho ! no harm done just a few quid...
 
I sympathise.

Every time I go near one of these cars "something else" is found. My one is away having the clutch done today and I am anticipating the call to tell me what other problems have been discovered.
 
Oh the joys of owning an older car..or better known as a "Classic" [:)]

All my problems at the moment seem to be suppliers sending me parts that don't fit my car!! [:mad:]

Aaah, but you have to think forward through the snow and sleet to a warm dry sunny day and a deserted bendy road in the countryside....makes it all worth while! My "clutch replacement call" was "might as well change the slave cylinder" for a quick £100 then they mangled the TDC / RPM sensors, but at least when new sensors were fitted it ran better than ever before..

There are several reports of this sort of thing, but I can't understand why new sensors make a difference. If the system is digital (i.e. the sensors are returning a signal pulse) then surely it either works or it doesn't? Why does a new sensor improve a previously operational system?

(And is replacing operational sensors a good idea every x-thousand miles or so?)

When I did my clutch I tried my hardest and spent several hours trying to remove the sensors from the bracket which you need to do to withdraw the clutch bell housing. Invariably they are seized into the bracket due to age and will break without too much trouble. Unfortunate but a fact of life. They are Hall effect sensors and they can deteriorate with age but also I guess when the new ones are fitted they are installed to the correct clearance as they were when they left the factory, thus returning to the original equipment performance.
 
Yes, but if all they are doing is sending a pulse at the relevant point (i.e. digital signal propagation) then it either works or doesn't ...

and the call has come. I think I'll go off and cry... or comfort my wallet... or something.

Yes, correct in theory, but after 150k miles and 23 years... Digital is never actually pure on/off digital of course, but a pulse, usually a "raised cosine" format. Who knows what the waveform looks like after that time/mileage, and as you say, the clearance was probably wrong too. Clark's site is good on setting the clearance, but you do need to be able to get the pesky little blighters out to do it. All I know is that new sensors gave the car much more grunt below 3k revs, which is as it happens a critical engine speed in the management system. I was a bit disappointed with the low revs power when I got the car, but after the new sensors were fitted it now has that low-down stump-pulling torque that one would expect. No idea if a routine replacement is a good idea (like exhaust O2 sensors for example) but as our 944 was de-catted on the factory production line, that is not relevant to mine anyway. The (OEM) sensors were bought cheaply on eBay.

Uh oh, what else was found? Maybe the collective wallet clenching of the entire forum can reduce the pain [:(]

Oh... split reference sensor sleeve, badly worn gear linkage, split CV boot, leaking gearbox seals, a bodged and leaking fuel line repair and some other sundries... Now... to be fair I did say "it hasn't seen a specialist in a while so please let me know what else you find". Ask an ye shall received I guess.
 
Just think how much better it will be than before, with that lot sorted! Damaged wallet but big grin, fair exchange? You would probably only otherwise waste the money on stuff like clothes and food for the kids, mortgage payments etc.
 
Oh I suppose you're right... I just have trouble with people who keep telling me what a "superb example" it is (that often happens) whilst at the same time suggesting yet more things need doing...
 
Update on the oil sleeve issue - spoke with Lindsey Racing today - simple solution = rub the crank down with emery paper so that the sleeve runs easily on it prior to installation !
