03 jetta tdi, timing belt broke. Is the engine an interference engine, if so does that mean i bent the valves? Engine has 240,000+ miles, previously ran fine. What do you think is the cheapest route for repair?
Hi i have an afn engined passat .. snapped belt .. all its did was break the four hydraulic inlet valve lifters . the valves which run vertically with a large contact area ..all were in place .. put them in a lathe ..and a dial guage .. run out still within new tolerance ..all this at 240000 miles .. cost me 80 quid so far for the lifters and a top end gasket set
don't be too depressed sometimes its easy :)
That many miles a replacement new/used engine would be a better route in my opinion.

The number of miles is not relevant, because in 7 years of driving, obviously it was mostly highway miles and caused little wear.
It only takes about an hour to try just changing the belt. You need to buy a belt anyway. So it is always worth the attempt.
Most VW's have small depressions in the pistons for the valves, to prevent anything serious.
But no, I do not believe the TDI even is an interference fit.
Only the DOHC GTI engine was even close. I do not believe the TDI had a dual cam version, nor was any Jetta dual cam. And it is only with dual cam that the valves hit, because they are on such a hemisherical angle.

Sorry to hear that.
My mistake is probably from the fact I don't do much diesel work, and diesels have much tigher compression chambers.
While I could suggest lots of inexpensive places to get a head, I am now unsure what to suggest?
If the head is that bad that you can't just replace a few valves, then I have to wonder about the pistons as well?
But here is a place selling new heads for $315.

Places like eBay can be good, as well as Craigslist.
Its turbo lower compression but no valve recess

Thanks for the help, yes the engine is an interference engine and the valves are bent. I removed the head and it's severely damaged. Any ideas for a re-man head cheap?
Take the head to a machine shop valves are not expensive head job costs 125 shaved cleaned valves replaced never replace a head just because the belt and valves broke only when cracked
