I need someone SMART.

[Attoir]

Alright, I need suggestions on how to trouble shoot this.

I did a balance shaft removal, and a timing belt replacement.

BS removal went smoothly, did it the 'free' way, nothing worth mentioning.

Put everything back together, and am now attempting to put the timing belt on.

I have new OEM-
Timing belt
Idler Pulley
Tensioner
Tensioner Pulley

I set all of the marks to line up properly, (ALL marks are correct, cam dowl pins are at 12 o clock and marks straight across) put on the timing belt and the proper amount of tension.

I then rotate the crankshaft about 30-40% clockwise. It then STOPS firmly. The spark plugs are out, so it's not compression. And it's not just valvesprings, it's a very solid stop. Feels like something gets jammed.

I rotate it ~80% counter clockwise, and it does the same thing.

Probably after the 3'rd attempt, I got upset, and forced it. The timing probably jumped 2 or so teeth, however, after that it rotated smoothly all around.

Whenever I line all the marks back up correctly, and attempt to rotate the crank again, the same thing happens.

I've done the timing belt procedure LITERALLY six times. Hoping I was doing something wrong. The problem is the same EVERY time.

Someone help. =/

I'd check your cam timing very very carefully, sounds like a piston meeting a valve. When you forced it, which was a bad idea, where did the belt slip? You didn't forget anything under the cam cover or in the oil pan did you? Do you still have your lower sprocket belt guide, you should. It's the flat piece of metal with the notch cut into it for lining up crank timing. Make sure the keyway in that guide isn't worn and spun on the snout of the crank a little bit, that will throw your crank out in a hurry. Also, you should have kept the front balance shaft drive sprocket (the one on the crank) to securely hold the guide. Another way to check this is put the lower timing cover and the harmonic dampener on and make sure the marks line up at 0, then, without turning the crank, take it all back off and check your index on the guide and front cover.

Hope this helps

Stupid question, but did you take the transmission out of gear
