Post 85.5 n/a.. Is this true?

So my valves are shot, most likely burnt up and at 120k it's about the right time. So I have 0 time right now or anytime soon because of school and marine training this summer, so my parents are gonna help me get it done at a shop.

The mechanic said that there could possibly be a need to redo the pulleys for the timing belt and water pump because on some cars the factory setup was inferior? He estimated like $2500 for the job so I was like wtf? Is there any truth to this? never heard of it before.... I'm in the bay area right now, if anyone could give me some info. How much does replacing valves and headwork usually cost anyways?

Sounds like you need to make a trip down to Partsheaven (right in your back yard) and look for a used 944 NA engine.

How do you know the valves are "burnt up"?

Did you do a compression test? If so what was the results?

There are a myriad of faults that can give the impression of bad valves.

PS: I've seen maybe two burnt valves on 944's in the last 19 years. And only on one cylinder. These engines will easily last 200,000 before any surgery.

Well not necessarily burnt, that's just a possibility but there's definitely something wrong with em cause they are clacking pretty good. Just what the mechanic said. Why would i need a new engine because of valves? Theres a good possibility that the used engine is going to need a valve job some time too.

I was just reminding you that for $2500 smacks there are other options in lieu of engine work you might want to look into. Especially when you're in California, and even more so when you have a dismantler as important as PH next door.

However, like SoCal said, it may not be as serious as you've been told. Perhaps you should get a second opinion. I have a 1983 944 with 202K miles and the valves have never needed servicing.

Good luck with it.

Most likely your hydraulic valve-adjusters (lifter) are stuck from gummed up oil residue. Just run some B.G. stuff through there to dissolve the sludge and you should be fine.

I have to agree with Danno.

The worse thing that ever happened once with my '85 944 was that I had lost all oil pressure, on start up. It was gummed up with oil, and it had to be rotor-ruetered out (ex's are ex's for a reason! Last time I trusted him to get me an oil change - WRONG OIL).

The other thing that bothers me about your Money-chanic, is the:

"The mechanic said that there could possibly be a need to redo the pulleys for the timing belt and water pump because on some cars the factory setup was inferior?"

I'd get a real mechanic that's Porsche certified; this guy just wants your money!

Best to you in this endeavor!

Sounds like the mechanic is burnt out. My vote goes for lifters. Are you sure it's not just our noisy injectors? Most cars I've seen with 1 bad valve will make the engine miss or backfire never mind multiple bad valves.

I second getting a second opinion, at least from a serious P-car person.

check this quickie Porsche page that I made those that live here in the bay area for us here at Rennlist. The data is for mainly Porsche mechanics here in SF Bay (if anyone has additions to this list, let me know):

<a href="http://www.ddurrelltech.com/pcar/mech-sfbay-list.html" target="_blank">My P-car list of mechanics around in the SFbay 'hood..</a>

I would go for European Autoworks in Mountain View - although Carrera Motors is closer to you and are well recommended by a lot of PCA-GGR guys/gals.

love that font.
