Timing @#%@#$^!@#$ Jumped!

[BlackWhiteBeast]

Ok, last week I was driving back from a friends house just minding my own business and out of no where my car hesitated for a split second and decided to bog down and turn off on me. I pull over to check to see maybe if I blew a intercooler coupler because I just got done installing my FMIC 2 days prior. I was thinking hmm that's odd because I wasn't even driving hard; I maybe built 5psi on the boost gauge just to merge over. Well I checked all the couplers and checked if anything came loose anywhere else. I goto start my car and it turns over a little and then it just starts to make this whining noise like there was something wrong with the starter. I call the FLATBED and tow the car home. Well I get home and take the upper timing belt cover off to see if the cam gears turn while I try to start the car, and NOTHING zip NADA NO GO! The crank turns but the cam gears wont move an inch.

This is crazy because I haven't even put over 4,000 miles on this new engine and timing belt. I got my engine built by a shop that specializes in DSMS and this is just frustrating. The sad thing is, I wasn't even driving my car hard when it happened. My car hesitated, which probably meant my timing jumped, then the car bogged down and wouldn't start anymore. I haven't checked the damage, but when I try to start my car the cam gears wont move. The timing belt seems to still be intact from the top, and the belt is tensioned pretty good. I just don't know what to do now. I guess I'll have to go ahead and get a new head with fresh new valves and everything else. The head that's already on there was rebuilt by Clearwater Cylinder Heads. I got the head when I rebuilt the engine. The engine has eagle rods and wiseco pistons yada yada yada, this is ridiculous. Someone help me because now I'm in the country and no one out here knows about DSMS! I got the engine built and everything done in California and now I live in Mississippi. This sucks!!!!

Well it's good you weren't going wild when it happened. Imagine breaking a timing belt at like 6500rpm... Just take the head off and inspect everything. You may think all you need is some new valves, but you might have other stuff going on. So just look over everything before you order anything.

Sounds like you sheered the teeth off of the belt.
What type of timing belt is on there?

Its ugly witnessing this. You end up finding valve heads embeded into the pistons

It almost sounds like his camshafts locked up on him? I mean, unless he manged to shear EVERY tooth off of the timing belt...

By the way, not every timing belt mishap = destroyed valves. and it may only be one side versus both. Typically when a timing belt lets go under moderate conditions the damage is not all that bad.

FYI, on the one car i took apart, the balance shaft belt broke, and the result was the timing belt didn't break, but rather all of the teeth on the belt around the crank pully got ripped off. This occured while sitting at a stoplight, and accelerating away, and all of the exhaust valves came in contact with the pistons. Lightly, but they all came in contact.

mine did the exact same a few weeks ago while coming to a redlight. I had a timing belt job done 27k miles ago, which was a year and a half ago. Its funny how the motor had 189k miles and the thing thats caused it to break is a stupid piece of rubber. Timing belts....the most ignorant idea I have ever seen.
