VW 2.0 timing marks not seen on the crankshaft or engine casing. I do see them for the camshaft. What am I missing? Also Im at the point where Im putting the timing belt back on. Before I turn it over Id like to verify if the valves are bent. I have a compression tester. Is there an easy way to verify using compression or some other way?Its dependent on the exhaust or compression stroke? How do I align the crank I think A cylinder has to be tdc but I dont know which one and dont know how to put it there.
The crank mark is on the crankshaft damper/pulley

great this is what in needed. Would you have an image that show how the serpenteen belt should be installed?

I just replaced the timing belt and everything is back together. I checked the timing and both the cam and crank marks are dead on. Engine wont start. I get a few puffs of a back fire...thats it. I've been told by some experts on this site that the engine IS and interference engine but other experts said its not. Seem to me like it. Can you help me verify it is once and for all? I don't mind taking the head off if thats whats necessary.
A fast way to check this is to do a compression test on the cylinders. If you are sure the belt is correct. You should have good com-pressure on the 2nd turn of the engine over 120 PSI. If you have no compression any or some of the cylinders, you may have damage to the valves. It is an interference engine, I have seen some get lucky and not do damage but from what you are saying I think you may need to remove the head.
