Hi all!

Hi Ollie
Another possible source of a missfire is the injector wires. Try wiggling those too.
At least you don't get a belt of them!
I'm still guessing tappet though.
I use.10/40 but is suggest a cheap 20/50 as Pete suggests and change it again with a full flush again in the next few weeks, before the weather gets cold.
Good luck and has anybody asked for pictures yet?

Well its only fair, the amount of pain I've received helping him with his Land Rovers!

New gaskets is a good call. Where's the best place to get them?

Ollie

Fair swap then![]

 

[Ollie.w]

Ok, so how long should I run it for before admitting that it needs more than just an engine flush?

Given all the wires a wiggle and it all seems to be running ok. Also had the plugs out and they all seem fine.

I will get some nice photos when its a little drier outside!

Thanks once again for the help guys.

If I'm reading this right , that is, you've flushed the oil and put new oil in then I'd leave it running for a while to give the new oil chance to get that tappet working, if indeed that is the problem. Naturally if any new worrying sounds occur, turn off immediately , if it is the tappet and it begins to build up hydraulic pressure with the new oil it should begin to get quieter, however this is no guarantee that the problem is fixed for good but it will confirm the tappet theory. It would still be advisable at some point to renew the offending part, how long you get from the weak one is anyone's guess.

good luck

Hi Pete, I've had it running for 30-40 mins and its not changed unfortunately. Its not got any worse, I guess thats a bonus?!

Next step fitting a new tappet? How do I know which one to replace? Or is it best to replace the lot? Sorry if I sound like a fool, its something I've never had experience with.

Hi Ollie

Submerge each tappet in oil and try to compress it, it should be solid, if you can compress the tappet still after a few goes allowing it to build up pressure then it is bad, going by what you checked earlier I'd start with the two for cylinder No.4. There's one more thing that you can try first http://www.autostartonline.co.uk/wynns-hydraulic-valve-lifter-treatment-350ml-133-p.asp If that doesn't cure it then yes I think it may be time to remove the cam tower.

I think i'll just go for it now. what do you think about Porsche parts vs. other brands? These seem very cheap... LINK should I be worried? its just the original Porsche parts seem expensive at £150 vs. £26?! I will tackle it this week if I get a day off.

I'm not a great fan of after market mechanical parts, especially when they are vastly cheaper than OEM. However changing a tappet is not that big a job and if it doesn't work at that price your not loosing much, i would try the additive I gave first though.

Pete

Might be my ears/laptop but that sounds like the exhaust manifold is leaking. Also the dizzy cap doesn't look oem.

 

[Ollie.w]

I will try and get some of the additive, worth a go. That was my thinking on the tappet front, I can buy 6 for the same price as 1. As long as it doesn't do any lasting damage its a far better deal.

I think you're right, the dizzy cap isn't original looking on the internet. Should it be black? Will have a closer look at the exhaust manifold, don't think it is though.

Hi Pete,
Its had the problem for some time, though I haven't given it a proper running in some time. Unfortunately it happened when I was short of time and money, so I covered it up and popped it into the workshop. Now with more time and a little more money i'm keen to sort it. With the little running I have given it 30-40 minutes, its got more noticeable. It started as an almost unnoticeable sound.

Hmmm.. doesn't sound as sharp as a stuck tappet usually does, try to find out were the sound is coming from,use a large flathead screw driver or something similar. With the engine running and with the handle of the screw driver pressed against an ear, try touching various metal parts of the engine close to where the sound is loudest. Keep moving the blade of the screw driver until you find the loudest place that the noise is coming from and report back. Be careful when doing this that you don't get to close to any moving parts.

...while keeping a watchful distance from any belts and fans. []

Hi Guys,
I have now tried the Wynns lifter treatment and had no luck unfortunately. Im getting cold feet on replacing the dud tappet myself, what do you think I'm best to do? How easy is it to do with a little help and guidance from you guys? I have a garage which is happy to do the job for £45 per hour, how long do we think its going to take?

I will go ahead and buy the parts to do the job and see how i'm feeling when they arrive. What parts am I likely to need other than the new tappet? Which gaskets should I change?

Once again thanks for all the help!

Hi Ollie

first of regarding how much from a garage, the job shouldn't take too long, for a trained mechanic probably no more than an hour, most should be able to do it in half that time but if using a non Porsche specialist I'd allow for at least 2 hours labour, could be more if they charge a full hour if going over by a few mins.

Regarding parts needed, certainly you'll need the tower cover gasket and the tappet , if i was you I'd wait on buying parts until you have the tower off and can see exactly what you need, things are not always as they seem. You need a good tool for removing the tower bolts as they may be a little hard to get undone, iirc it's a 6mm hex but could be bigger.. it's been a while...lol Something else worth considering is renewing the timing belt while your in there, be warned the list of ' what to change while in there' can get very long. You may wish to replace the tower bolts as they can get damaged during removal if using a cheap tool and they are more stubborn than usual.

Look up the workshop manuals on this forum so you know the various stages involved and I'm sure you'll have no problems in doing this yourself.

There are plenty of guys who can help you on this forum if your unsure about anything, they may also suggest something that I've forgotten, now I'm off to get on with mine so good luck and have fun..


Pete
