Are you positive that you had .003 on all mains? Have a circle track friend that had exactly the same results that you have had with the same little m block. His engine builder missed it twice and now he has a new builder.

We refer to "wet mag" as an FPI process in aviation.
Fluorescent penetrant inspection (FPI )
I've never heard it referred as "wet mag".......but I believe that's what you or Mike mean.
And yes , I have the option of using traditional mag or FPI.

I am 100% positive. I am the "builder" . I am a "machinist" of 40 years and use the most accurate currently available gauges used in our shop ( aircraft ).

SO ........there ya have it.
Disgusting isnt it.........:mad:

Re: A follow up to "oil starvation issues" thread
 

Glad you caught it before things turned into shrapnel. Amazing how the rod brgs. look perfect and the mains are hammered. Aeration, too much oil upstairs, an internal leak...likely a combination of things. Are you going to change where you source the vacuum or eliminate the pump all together?

Re: A follow up to "oil starvation issues" thread
 

The mains have a constant load where the rods don't.

At least its on one piece and you still have something to work with!!!!

wet mag is FPI when translated from hillbilly. Use the FPI on crankshaft.
If I didn't know anything about this crank and came into my shop,my first guess is it's cracked and would be surprised if it isn't.
I can't tell in picture but has the radius been ground less than original. Been reground and radius reduced? Normally BRC or any aftermarket crank would have 1/8 (.125'') radius at the least,can't tell about crank in picture,but rod bearing doesn't look like it would clear a .125'' radius,looks like it doesn't have the chamfer or narrowed to clear, if radius has been reduced that weakens crank.
