A little history here. Porsche did dowel the case halves together on may engines. They used the through bolt with a stepped center to do the same. A little plug here, PD is in the process of remaking our head studs we used to sell years ago before most, along with these doweled through bolts. I remember Henry coming to my shop and looking at our studs before he made his.
Whatever means you hold the two case halves together and stop from moving is a good thing. These cranks are heavy and the strokes are quite big. The crank moves around a lot and all this movement is transmitted into the bearings and into the case holding the bearings. The nose of the crank moves the most and acts like one of those pool noodles you buy. If you watch a crank at 7000 RPM it will scare the life out of you, how much it moves.
As for gluing the bearing caps, I would never do it as it stops what from leaking? Glue is applied for one reason only and that to stop leaks. If someone could tell me what can leak if no glue is applied here, I'm listening.
Could it change the bearing clamp? From some of the photos posted on this forum showing how much glue is applied on parts of these engines, I would say yes, absolutely. Heavens forbid, is it applied under the guise of, some is ok but more is better????
Why stop at one bottle, hey the store you bought it from has more, so get more and keep gupping it on. It may help out balancing out the corner weights????
