Timing belt failure

Is there any chance that the water pump goes out taking out the timing belt and the valves donít get bent? 1983 944 na

100 percent chance of bending valves.

yeah i was looking at this car where the water pump went out. The kid replaced the water pump and timing belt, the car wouldn't start, now he is trying to sell it for $1500. paint is bad, needs bodywork, bad interior, sunroof is sealed with caulking. think i'll pass.

Not quite 100%. A friend, Dick Howe, lost the timing belt on his 944 Turbo many years ago without bending any valves. Porsche told him that there's a 3% chance of not bending valves. Can't say where they got that number, but Dick was lucky that time! (And luckier than me, when my 944S broke its timing belt just before Porsche realized that, uh yeah, the belt they originally used on the new 16-valve engine was not up to the job, here's a new Kevlar-backed belt.)

It's hard to know what to do with a car like that. Spend money on the engine and you've got a cosmetically crappy looking car for 1500+2500=4000. Add body work and you're at $8000 and still have a cracked dash and shabby seats.

Kinda sad but that thing may end up in the scrap yard now.

All right, 97 percent chance of not bending a valve!

I do remember "The Beast!"

I can believe the 3% chance of not bending a valve(s). I always thought there might be a sweet spot where all the valves would just clear the pistons when the cam stopped turning.

I think this is a lotto win type luck! There's interference engines and then there's the 944...

Maybe thatís on the early naís and turbos as they use the same (lower lift) cam, the later naís I guess the odds are worse.

I bought a super clean 86 with bent valves for $1000 about three years ago. I installed a fresh head and ended up selling the car to a guy that absolutely had to have it. All in all I think I had about $3000 in the car with parts and purchase price. If the car you're looking at is super clean then I say go for it. But based on your description, I think I'd offer near $500.

$500 is the high end for this car. The alternative is scrap. I bought my 86 for $500 and it is in better condition and it is going through a complete teardown and rebuild. This car would need the same.

For that price and condition, I'd pass. Who knows what other evils are lurking beneath the surface?
