How to tighten motor mount bolts?

[Silver4]

I feel there must be a trick or technique to this. I removed front engine mount bolts and right front engine mount and loosened rear long engine mount bolt about 3/4 turn to tilt the engine for the infamous starter job.

I am now reassembling, and I started by tightening front two engine mount bolts, (one at a time) but I can't get more than a quarter tightening turn on the nut on the rear. I marked it for reference and it should go at least another quarter -half turn. What have I done wrong? Is there a sequence to this or something? Does the engine still have to be suspended well taken in the engine bolts?

True, it is possible the rear long bolt swiveled during the tilt process but the question remains... is there a technique to tightening the 3 engine mount bolts?

Since you only loosened the nut on the rear mount and didn't loosen the spacer and remove the long rear mount bolt, you should only need to tighten the nut. Maybe the nut self tightened a little when tilting the engine up and back.

Yes possibly, is there a chance that the two front mount nuts put the engine out of alignment and shifted the engine so that the rear nut couldn't tighten as much? Or maybe the shaft got moved away from the nut and the weight of the engine is keeping it from moving back so it can be tightened. I have no idea how spacer enters into this. Doesn't seem like anyone else mentioned spacers or issues tightening rear engine nut when doing the doing the starter tilt. hmmmm

That bolt has a carriage head on it, maybe it isn't fully seated in place...?

Grizztracks procedure(in the blue section atop this forum) on replacing the cam tensioner will update you on the spacer used on the rear engine mount. Carriage bolt head is in behind the secondary clutch.
