Plastigage Clearances - Does this look right?
Just plastigaged with the green stuff and measured the following
Main #2 - .052mm
Main #3 - .077-.08mm
Main #4 - .07-.075mm
Main #5 - .051mm
None had taper
Rod Bearing #1 - .038-.042mm
Rod Bearing #2 - .038mm
Rod Bearing #3 - .025mm - EDIT re-measured this and came up with .035mm
Rod Bearing #4 - .040mm
All of these had a slight taper - with more clearence towards the "back" of the engine (flywheel side) and less clearence towards the front on the order or about .005mm.
Does this look reasonable? Forged rods / crank from an 83 8V engine running in a 16V block and upper end.
The oil port to the balance shaft bearing of the #3 main will be plugged - engine will run without balance shafts!! >_>
Thoughts? This look good? THANKS Paul
