Default Timing a 02 F4i

so i have to time my engine and i got it all back together but it wont turn all the way around. i thought i had the marks lined up right but now im not sure. does anyone know the exact marks that have to be lined up? ive searched and all i find is that i have to line them up but thats all they say. theres a T with a mark by it and an F with a mark by it and there was also a mark by itself all of these are on the crank. PLEASE HELP!!!!!

Have you already tightened the cam hold down plate?? If so and you're trying to rotate the engine with it out of time, you're smacking the pistons into the valves... not good!! The cam hold down plate and cams must be removed so that all the valves are closed, then rotate the crank to the correct position. The T and F marks stand for timing and firing. You want to line the little mark next to the T up with the groove on the clutch cover, like this

Then install the exhaust cam, and line up the little line under the EX mark so it's flush with the surface of the head. Remember both the intake and exhaust cams use the exact same cam gear, so both have marks for intake and exhaust cam timing, be sure and use the appropriate mark. It should look like this when it's all tightened down.... might take a few tries to get it right, it can be tricky as they turn slightly when you tighten them down

Then install the intake cam and line up the line under th IN mark with the head

Then TORQUE all the bolts on the cam hold down plate in the EXACT numbered sequence stamped on the plate. Not doing this WILL result in a broken camshaft

And it should look like this when you're all done

And of course the crank should still be lined up at the T mark. Install CCT, then rotate the engine several times (usually takes 4 complete revolutions) and make sure the timing marks still align as they should, and you're all set
