So I just bought a 1986 944, and it runs great, except for one thing. Sometimes, not always, but sometimes when I turn off the key the engine doesn't really turn off, it makes this horrible loud clicking sound. The p.o. said it was something with the vacuum? Sound familiar? Any help would be greatly apprciated
Thanks

 

sonds like bad timing/detonation to me...

 

Thanks
How do I fix that problem, adjust timing?

 

Please need more details. First of all, how long has it been since timing belt service?

 

I'm not sure when the timing belt was last changed/tensioned, as I just bought the car and the p.o. had no info on that.
However, I do plan on taking it straight to a shop to get the belt changed as soon as i register it.
(on a side note, any idea how much timing belt service will cost me?)
Thanks

 

someone446, where do you live? In the US? city? Someone here has probably been to the shop you are considering, or can recommend a shop.

Are you sitting down? Unless there is more to the wealth of information that you are sharing, like last name Porsche or something, $1,500 to $2,000 for timing belt service. Going to my Porsche mechanic was like visiting the doctor, a pleasant doctor. There is a lot of things that need to be done at the same time, skipping any may cost you $1,000 in labor for a $10 part, 6 months later. There are a lot of $10 parts, so they add up too. This is how my mechanic put it, and I gave him free reign to do as he saw fit, no need to call me for approval. Anything that he thought need to be replaced was. And, I am still spending a small fortune on all the neglect caused by P.O.'s. plus, it's a 20 year old car, some stuff is just plain worn out.

So, if you are still with me, let it sink in for a few days, than I recommend making a commitment to not driving the car until the service is preformed. If you can find the service record, okay, but a lot of P.O.'s sell the car once they find out what it will actually cost to own a Porsche. At least there is comfort in knowing that there is no substitute and nothing else compares.

 

I'm in katonah, which is around 40 minutes north of nyc, in westchester county, ny.
I have a guy who I use in queens who's good. He worked on both my mazdas, but I'm not sure if he does porsches. Ill have to ask him.

 

There is a speciality Porsche tool required for the job. Most mechanics do not have, and some don't have and don't know they need. Plus shop manuals, getting parts, knowing what to replace, etc. You really are so much better off going to someone that does Porsche's. Plus, there is also a warranty, but has to be installed by a Porsche certified mechanic, not exactly sure what it is or how it works though.
