Kind of a lengthy question. I had to pull the cylinder heads in order to repair exhaust manifold bolts that were broken. Unfortunately, I was not able to do it from the wheel wells. Before starting the disassembly process, I went to position TDC, but after a partial turn, the engine would not rotate.
Being as I was all ready annoyed and not in a good mood that I was going to have to this repair the "hard" way, I didn't even think to put the tranny into neutral. I just ended up carefully marking and photographing everything so I could take it off as is and put it right back on. This would have worked, but after successfully fixing the passenger side head, I moved onto the driver side head.
Long story short due to a tool failing on me, I damaged the head and an now forced to buy a new head. I am trying to decide if I should manually rotate the cam to exactly match the old one and remount it that way or if I should just rotate the engine to TDC.
The problem is I can't rotate the engine counter clockwise, like the manual specifies since the crankshaft bolt is off and won't be re-tightened until I am done. I could rotate the engine clockwise without tightening the bolt too much, but I am concerned that I may damage the engine by doing this. Does anyone qualified mechanic out there know if this can damage the side I have all ready completed? Any thoughts on this dilemma would be appreciated.
