    rear engine mounts-gctid806518

    I installed new engine last week but could not get rear engine bolts that go through flywheel housing to grab the nuts with the spacers on them,so I removed the spacers and it tightened down just fine and engine lines up for rear drive shaft,will it harm anything to have spacers missing?

    Are you asking about the spacer units that install just above the flywheel cover mounting ears?

        It's odd that the bolts aren't long enough. For myself, I'd put the spacers back in and use a longer bolt. I don't think there's anything particularly magic about the standard bolt other than the pointed end feature at the threaded end. Btw, are you holding the nuts in place using masking tape as you set the engine? It's a common way to keep the nut in place and makes life a whole easier.

              Spaceman, your using the newer style rear engine mounts? Not 100% sure but there may be a difference in the bolt and spacer length between new style and old style.

              Ricks image is of the old style mount with the spiral wound washer. The new style mount does not use a spiral wound washer but uses a flat stainless washer instead (part g) and I think the mount itself is a bit longer.
