Rebuilt 360, excessive oil consumption

1wild&crazyguy said

no. 8 has an issue.

but how are you breaking it in exactly, are you varying the rpm at cruise, or just keeping it steady?
you need to vary the rpm/speed every couple minutes or so.jmo

what kind of bore finish?

what primary jet size and pv are running?

and does the valve cover have a baffle to keep direct splash from the pcv?

Yeah but why only one cylinder not sealing? Rings can go on upside down. That would be my guess yet I heard of the wrong size rings-pistons in a lot. I never seen it but heard from builders it can happen.

Regardless, the head and oil pan need to come off and the piston pulled out and see what is wrong. If the rings are on upside down you may get away with just new rings and no honing. Means the crank can stay put. Yeah its a lot of labor. Like I said I'm getting brunt out on hot rodding
