Oil pump/stud interferance

Well, after much to-ing and fro-ing, I think I'll use a bolt, and there's a few reasons for that. One, the cap is on tightly in it's register and it's pin and two, the factory thought bolts were satisfactory. Three, I have no easy access to a milling machine to cut down the cap. But here's a question- the factory torque (on bolts) is 85 lb/ft, but I have Pioneer studs and in conversation with Pioneer's tech dept. they recommended 130 lb/ft! I don't want to pull the threads out of the block and wonder if anyone else has experience in this regard?


And that’s why I don’t mix studs and bolts. The stud needs more torque to get the same stretch so you have two different torque values on the same cap.

You change the torque valve and you can bet you will change the size/shape of the bore.

Chrysler used bolts because they are cheaper, not better.

You are in New Jersey. I find it hard to believe you can’t swing a dead cat and find someone with a mill to machine the cap down.
