Default Re: O-ring groove in flywheel housing

My experience has been that it is important that all six mounting bolts be torqued down evenly with the two .010 shims installed under the top two mounting bolts in order to get a proper measurement. In order to do this you need to obtain two shorter bolts for the mounting bolts at the ears because you would not normally have the throttle linkage bolted up.

The .010 shims are there to compensate for the gasket thickness used at the lower four mounting bolts. The problem is all the suppliers provide gaskets that are much thinner than the shims. For this reason I obtain gasket material from an auto supplier that is about .015 thick and cut my own gaskets. The .015 gasket will crush down to about .010.
