Unhappy just blew my timing belt on the highway

went out saturday to a function,in long island and my timing belt blew on the road,suffice it to say i did'nt make it to the function and just had my car flatbedded back home.I am expecting the belts and the water pump to arrive wednesday.besides that what else am i looking forward to repairing.i am not an expert wrench(in the engine dept.) and i am getting some help on this,from what i got from another pelican buddy on the island was that i probably bent or broke a valve or pushrod.anything else i missed? and just in case i did would anyone out there in the great U S of A have these parts ready to ship out if need be? what else i don't know i just did the transmission on my car a couple of month ago,trying to keep my baby alive!!the love for this car is costing me mucho dinero and mucho headaches. peep it.

Definitely bent the valves. Need to pull the head and take it to a rebuilder. Or buy a used head locally or off eBay.

When was the last time the timing and balance belts were changed?

When was the last time you changed your timing and balance belts and/or cam chain and tensioner?

oh i dunno i bought the car from a friend in jersey just before 9\11( one month after that disaster i stored my car away of all places at fort dix and it sat there for two years till he came back from his tour then i took it out got it running but never really worried about the belts i just did'nt use the car all that much but i drove it hard) and supposedly he had a 1988 944 motor put in (i would'nt doubt him) but i just never got around to it. so now i'm paying for it.

Here's a link to Clarks Garage. It has some photos of the potential damage that can be caused by a timing belt failure:

Timing belts are a three year and/or 30,000 mile maintenance item. If the car has sat without being started once in a long while then the timing and balance belts should be replaced ASAP like before trying to start it.

Not replacing $80 worth of belts can cost you upwards of $1,500 to rebuild the head and do the water pump and front seals.

Maybe this thread can be stickied in bold Caps. Perfect example of why belts should be changed. That way SoCal won't have to post pretty much same post once every 2 weeks. Or maybe we should make a locked thread that will tell first buyers what to do right after the purchase and sticky that in bold CAPS.

Yup!

Before I bought my '90 S2, I grilled my 914 mechanic on the '44. He just about vetoed such a buy without either documentation or an initial belt job--and the tensioner foot on the chain n the head, too. Since the repair on a worst case on the S2 motor can run over $10,000, I thought I would do it right, and had a shop (different mechanic) do it--just drove it, gently, straight to the shop. They say 5 years is OK under normal (exuberant) street use, unless oil is getting onto it.

I am so sorry to hear about the loss. And it's such a pretty car. Anyone that does not have records should replace their belts and water pump right away no matter what. I just did mine, at the Porsche dealer, paid $1300, and nothing needed to be changed. But the $1300 was worth my piece of mind. I only went to the dealer because I have never done it before amd it is very important to be done right. They also did all the front seals and gaskets as well as a new cap and rotor.

Good luck and hopefully you can have her back soon!

This is to: ilikemy944 most probably unless by a miracle of the allmighty above i did'nt do damage send me a form of contact in case i need you.again i'm trying to do this right, but at the least amount, at the moment. i've already spent more than i care to. i understand you can have the vavles redone by a machinist. i won't know till i get under the hood what the heck is going on.

I just went through the exact same thing you are dealing with in my '84. Mine ended up with 4 bent exhaust valves and 1 bent intake valve. I went ahead and bought all new valves and had a machine shop replace the exhaust guides and do a good 3 angle valve job. Have your machine shop check the head for straightness, but tell them not to machine it unless it is absolutely necessary. Replace all the seals in the front end of the engine while you have it apart, and also the oil cooler seals. Check and replace any vacuum lines that are cracked. Post any problems you have on this forum and we will all help you through it. Good luck....

Yeah, usually you bend most if not all exhaust valves and up to two intake valves. But you may get lucky!! Just PM me or something if you need it. It will probably go pretty cheap, and its not 'for sale' unless I'm asked for it.

Keep us updated on how it goes!

Hi, ive got a good used head, not from the same car your tranny came from but in great shape. Good to hear you ordered a waterpump also. Make sure the mechanic is familliar with tensioning the belts and using the correct torque values, ive seen "mechanics" who have done plenty of timing belts but get this car all wrong. The other part to order is a gasket set. It includes the cam tower, head gasket, intake exhaust etc. Before removing the head drain the antifreeze and do an oil change after the job is done. Do it right and retension at the correct interval afterwards. If you run into any bolts that are seized and need replacements you can drop me a line.
Regards,
Rich

I've gone through this.

Even though I had correctly replaced and retensioned the timing belt just about a year and a half earlier, I had a timing belt break on my 83 944 back on Mother's Day back in... I guess it would have been 2003. Weird - it was the same weekend as your belt failure.

It turned out that the woodruff key on the cam had actually stripped and when it failed the belts went too. I lucked out and only had one bent valve, and my mechanic always cuts me a break on labor because it used to be his car. The failure ended up costing me about $800 when all was said and done.

sorry to hear about that, and i just noticed something else that might need to be changed on your car (but didn't screw up the timing belt), in that picture both of the 8" wheels are on the drivers side, looks like the front left and right rear wheel will need to be swapped.

most tire shops don't notice this crap, as i had to take my father's '83 back to costco to have them switch the wheels exactly like that (and re-mount two directional tires as well).

ah, then i'm wrong! how do you get the fronts not to rub? i had 8" wide fuchs on the front of my '84 and the tires rubbed, with 215s.

from what i've seen it's a 'common' mistake (at least i notice it a lot) to have both 8" on one side or something ridiculous like that... lots of shops don't pay attention.

i have another pair of 8" fuchs, that i could have made a whole set of 8" with, but they rubbed...

hmm... what's the point of having 8" wheels in the front if you're only going to have 205's... stock size is 215 all around, even on 7's and 8's. I've had 225's all around on it (on 7/8) with no rubbing. truthfully, even with 7's/8's it still seems like the front wheels are sticking out wider than the rear wheels... maybe thats just a trick of the lighting though.

you wouldn't believe the time i had trying to find a single 7" fuchs wheel (i got one 7 and 2 8's in a trade deal)... and when i did it cost me $250!
