Re: H-I-J '76 Nova re-fit.
Todd, Autumn, and those interested,:D
FWIW - All my calculations, estimates, and comments were based on the kinematic viscosity of hot (190F-200F) 30W oil. The leakage flow with lower kinematic viscosity would be higher numbers.;) Being an oil patch brat, I have rather strong opinions against using 0W lubrication in engines as I was taught to err on the side of reliability. And I fully realize your experiences may vary, but you can't win if you don't finish.:cool: Regards, HB2:) Dissident |

Re: H-I-J '76 Nova re-fit.
Spent a few hours scraping gaskets and cleaning parts today. Additionally, here's a picture of a piston with the Line2Line coating after some dyno time.

Re: H-I-J '76 Nova re-fit.
I'll just throw my 2 cents in.....
A few more points of internal engine oil leakage are the rod side clearance, if the rear main has had the split chamfered for more oiling to the thrust faces, cam bearing clearance, seal between the oil pump mounting surface and the cap, oil pump body to cover leakage and gear end play..... Do you monitor the oil pressure at the front of the block or the rear? A bad oil filter bypass valve doesn't vent to the pan it just bypasses the filter... |

Re: H-I-J '76 Nova re-fit.
Pistons are off and rods are ready to be checked.
