The machinist said that the rods don't plastiguage well and if I bring him the rods, bearings and crank he can measure it another way to determine the oil clearance. The rods have been resized and the crank ground. What do you guys do here?
Thanks,
Dave

I use plastigage.

The only reason they wouldn't "plastigage well" would be if they rods moved during the procedure. Just do it with the piston in its bore and the crank steady.

Thanks Steve, will do.
I prefer to do everything myself, if I can. Then I know exactly what I have.

The reason I don't use plastigauge is that the housing bores aren't round until they are torqued. Plastigauge will get you close, but dial bore gauges and micrometers are the only way to go for precision measurements....IMO.
