Some very good info has been brought out here so far........thanks.

On the subject of assembly lubes, do you guys have a preference? I have some that are sort of like thick black graphite (almost like grease) in nature and some that are red, more like thick slippery oil. I have used some by the cam makers too, which I use to coat the journals, lobes, and bottom of the lifters. Any preferences there?

When sealant is used on some threads and lube on others (as in doing a cylinder head) does it change the amount of torque you apply to each? I guess what I am asking is, does the sealant change how the bolt reacts to torquing? Hope I am being clear on that one.

...........on sealers yes keep away from teflon and max tq on old or so/so faseners, as for lube i using joe gibs assembly grease your talking about the snake oil .elgin oil comp cam oil and the torco oil all about the same torco and comp more sticky about the same as others .and stp abit thicker . all works some better but all are helpers to stop a dry start . pre lube is going to wash most of the stuff in the pan but piston pins cam lobes valve stems all this stuff get lube very well with stuff that hangs on good .the best thing is to have it fire up off the bat .

sorry i ran you over ...i just jump in the middle so i cut it down

Who needs the book, you guys packed this thread full of all the good stuff already. You've all answered a lot of questions I had, and I'm sure others had too. I am going to print out this thread and take it to the shop for future reference.

Thanks guys for sharing your lifetimes of experience and learning.

Not a Pro builder by any means,but on two piece rear mains I always install the seal so the parting lines do not meet with the parting lines of the cap.
