MM951

So, it happened to me. 6-8" of teeth stripped off of a 7 month old timing belt (probably about 10K miles) - doesn't look good for the valves. I can't say I'm thrillled.

I have heard of this happening a few years ago IRRC, but I thought that batch of belts was gone. Anyone else have any issues recently? FWIW, I bought a conti timing belt kit from ebay for $175 shipped about 7 months ago, forgot the name of the seller..

Is Lindsey Racing the cheapest place to get OEM valves or cant someone point me in the direction of something cheaper?

Thanks

Same thing happened a car I had unfortunately


Thats why I got the Kevlar belt. Peace of mind

Did you retension the belt during that 10000 mile period?

I have seen the ebay kits and always wondered how old the parts were?

I just finished putting a Contitech belt (new Pelican) on today. Never have had a problem.

Sorry to hear about the belt failure and the damage to the engine.

If I needed valves, I would go used.

Hmm. I recently installed a new contitech balance and timing belt a few months ago...

Sucks because you did what you were supposed to and it STILL failed. Sorry...

Run a compression check on your motor.

I have seen two separate 951's break a timing belt and not bend any valves.

The first one was all taken apart and the head rebuilder reported no bent valves. So the head was put back on and the compression was great on all 4 cylinders, car ran great.

The second was actually one of my 951's, which stripped a few teeth also. I ran a compression test before taking apart the motor, and all 4 were dead even. Put new belts on the car, and just like that, it was back up and running great.

Summary: run a compression test, now!

Welcome to 944 ownership were everything no matter how new is subject to failure and your always reducing weight via your wallet.

.. I'm old school, Laust found a way to make this a clearanced engine while in the car..

there are far too many stories of people who make an exalted and superb effort to do the "right thing," to keep their older Porsches running in top form. others are blamed for making some seemingly minor, yet hyper-critical error that leads to some castastrophic failure. the inconvenient truth is that this is a very challenged engine design, not long after—abandoned.

Porsche made some good rollers with the run of the 944/968... from day one i've considered my '68 as a "kit car" waiting for lots of mods and as soon as the money starts rolling back in, it'll get a proper engine (that realistically fits my budget) — the result of a multi-billion dollar development program.

best wishes.

Funny you say that because it was used from 83-95. haha.

the car surely had it's time.... by the time the final (968) rolled off the line, the sales numbers had never come in to properly justify the superb quality built into that car. if i had a LOT of money i would personally love to own a proper 944 Turbo or 968 Turbo S replica.
