Need your help here guys.
So I am doing a bit of learning on this engine rebuild so pardon me if I miss something here.
I have a BMW M50tu with a 2.8 crank in it. I set piston 1 at TDC, Set vanos timing and went to rotate the crank by hand as a quick test.
it will not do a full stroke only half of one. At first I thought it was a timing issue and the #1 was hitting the valves but was/am confused when I realized piston 1 ins't stopping at TDC its stuck going halfway down, then when I turn it the other way it will go through TDC and make it halfway down the other part of the stroke and stop. WTF am I missing here. Sorry if I'm missing info here.
