Re: How much oil pressure

In my opinion, 20W50 oil is too thick to be run in any high performance/high RPM engine. Go with rod and crank bearing clearance set at the middle ground of the factory recommendations and shoot for maximum oil pressure of 50 to 60 lbs. oil pressure at maximum RPM levels. 5W20 or 5W30 synthetic oil ...

Re: King versus clevite

Whenever I read a post about bearings I always seem to see the same brands mentioned. No mentions of the Daido bearings that Callies sells. I have almost exclusively switched to this bearing and I am very happy with them . Sizing is awesome and I absolutely love the “floating “ thrust. It’s almost ...

Re: Plastagage versus bore gauge

I too have recently been playing with the conventional type bore gauges in measuring bearing clearances. With 2 different branded Japanese tools I get consistently similar results. With plastigauge I'm getting around 0.005mm tighter readings on a 2 inch journal. This is with a European platigauge e...

Re: Plastagage versus bore gauge

Victor-Reinz used to market impression paper which could be placed between two surfaces, such as between block and heads. The parts were torqued to specification, then removed. The impressions left on the paper would show the consistency (or inconsistency) of the two surfaces involved. Can't remembe...

Re: Bearing Clearance

An engine of this sort probably has a price tag with seven digits or so, therefore we can probably assume that the machine is being operated within design parameters and factory specifications.

Engineers say that is enough but we keep having failures.
What are the exact failures that you are encountering with this engine?
