At least that's what it's looking like right now. Here's what happened. A couple days before Thanksgiving I'd noticed my motor had started to stumble from time to time. It would do it both under load and at idle, just not very often. Then, the day before Thanksgiving I was leaving work to go to lunch and my TDI started like normal, except it puffed out a little smoke (it does that from time to time so I didn't think much of it). I got maybe 100 feet before the motor straight up died. When I went to crank it again it seemed like it wasn't making any compression because the starter didn't seem like it had anything to work against. After taking it to my normal shop with no help I took it to the stealership where they found my compression was 3/4 what it was supposed to be on cylinders 1-3 and #4 was at less than a 1/4 of what it was supposed to be. Their guess is a bent valve or a cracked piston crown. On top of that, they said the timing was dead on and the timing belt was in perfect shape.
So here's the deal. I replaced the timing belt only 26,000 miles ago, my oil and filter changes were all up to date. I've been using B20 biodiesel on the regular from a reliable source for several months. So, what could've caused this? I'll update when I find out the specifics on the problem.
