To quote Dieseldorf: Do you know what kind of car you have ??
Your profile doesn't help...
If you're talking about an ALH motor, there's also a mark on the back edge of the harmonic balancer, which lines up with a small line pressed into the lower timing belt cover... you can use that to help decide which mark on the flywheel is the correct one...

Yes... sort-of... (the engine's not perfectly vertical...) The mark on the back edge of the harmonic balancer looks like a tiny semi-circle that's been chewed out... the mark on the timing belt cover is also hard to find... looks like an embossed scratch...

The easiest way to find out where it is, It's probably to pull TB cover out, rotate the engine until you could stick the IP pin in the hole then go and see on top of the tranny underaneath the coolant glow plugs, you are going to find small plug, pull it out and you should be able to see the timing mark on the fly wheel.
But I think the most accurate way would have to be to use the cam lock to lock the cam then pull the plug out from the on top of the tranny, you should be able to see it there, if the flywheel does not have a marking then you can stamp it right there.
FYI, My Sbc 3 that I recently installed did not have a marking on the flywheel, so I had to stamp it.

I put the cam lock in and the mark on the flywheel is off a good 1/2 inch but there's 4 marks. When I lined up the first mark the ip lines up but the cams off so I'm thinking before I re set the timing want to make sure its the right mark so I don't cause problem.Would it run with the cam off that much???MAXRPM said:

As of matter fact, I just finished doing what you are trying to do, I had the same problem that you had with my SBC-3, if you are real anal like me, and you really would like your timing marking to be dead on, get your Vag.com program and line up the timing chart right on the center by losing the 3 IP bolts and moving the center of the IP, once you get it dead center on the timing chart stick the IP-pin, then go to your flywheel and mark it, also I double checked it by sticking the cam lock and it was dead center, so that is how I did mine and it came right on.
FYI, by just having the little play even with the cam lock in the lock position if you turn it to the far right or left, those marking on that you are seeing on your flywheel, move so far, so the secure way is by using the vag.com and center it and sticking the IP-pin then mark it.

You can't assume that the car is mechanically aligned before you started working on it!!!! Sometimes they're off right from the factory... as well, the camshaft sprocket could have slipped...
You should definitely NOT mark the flywheel to synchronize with the locked camshaft !!!! That means that in case your mechanical timing between the cam and crank isn't perfectly aligned, you will be memorializing the wrong alignment...
If you don't have a mark on the flywheel, you should use the mark on the harmonic balancer as an almost-accurate guide, and then remove the glow plug on Cyl. 1 and put a probe down in order to measure for the actual TDC...
