Sorry to hear about your problem.

I agree with Jim, you need to take the engine apart to find the problem causing the crankshaft's hard rotation. Beginning with inspecting the oil pump, the lower oil pan may contain debris that will tell you a lot. If the oil pump looks OK, you will probably have to do a TDI (tear down & inspection). Perhaps other member(s) have had a similar problem and have the "silver bullet" cause and cure, otherwise TDI.

By the way, do you recall how many teeth the timing chain jumped and/or the number of degrees the crankshaft to camshaft timing was off?

Good Luck!
Tom
