Thanks! Head came off last night. What a mess I might just go for an engine. NOt sure if the pistons are bad but they did hit the valves. Only two marks on the Piston from the center intake valve on the two center cylinders.

This is my Timing belt story. I was driving up the road maybe doing 15 Mph and the thing stripped and I bent valves. You think Audi would have made a non interference engine using a belt for timing. I guess this is one way to keep thier technicians busy with work as well as the control arms.

 

theres plenty belted interference engines out there, but other mfg.s make it either; so you dont have to put the car in service position to change, or pick a correct recomended milage to change the belt at.

problem with audi is that some genious decided 90k mile intervals were good enough, but didnt realize alot of the time they start breaking around 60-80k. oops. and it also takes a several hours worth of work to get to the belt and change it

if you wanted to make the 1.8t a non interference engine, while keeping the same compression ratios and displacement, you would need to make the cylendars narrower, with a longer stroke and more head volume to move the valves away from the cylinder. a longer stroke is ok for a diesel but not really for the average car.
