There is a time and place for PG. Mostley quick check or double check work. That stuff has been around longer than most of you. With our motors and what we do here it's time to break out the tools. Didnt we do that motor here, or was it just the top end?

We see alot of motors around here. The one I DO remember was Jay's cam 45* out and running

WAIT!! If you are looking for a measurement smaller than .0005 and you are using plastigage, just do it over and over until it gives you the number that you want. It will vary atleast .0005.

Problem solved! Next.

just wondering 

Will this work with precision tools as well ...just curious 

I've heard some people mix the a 0.001 under shell with a std shell to arrive at .0005", but it seems like that would have kind of a screwed up parting line...there would be a 0.00025 step, which I'm not sure will have an affect on anything.  So, out of all the different ways to skin the cat...what's the prefered method of hitting the mark?

I've done that a time or two, still means buying another set of bearings though.  Never gave me any issues.  Clevite even mentions doing just that somewhere on one of their tech pages.
