Rebuilding a 1985/2 2.5L engine. The main bearing cap does not seem to align well with the block, as there is a noticeable ridge between the block and the cap at the front of the engine. This is where the oil pump is supposed to mount. The Porsche manual mentions something about a fingernail test, but doesn’t go into details. From the way things are drilled, it looks as if there should be a second alignment bushing at the front of the engine, in addition to the one at the rear. The PET catalog shows only one, at the rear. I have considered quickly bolting the oil pump in place prior to torquing the bearing cap in place – but I am worried about the working time of the block to cap sealant. The shop manuals mention flattening the area with a stone – which seems like a risky proposition. Any help or experience out there?
