Fresh rebuild, oil everywhere

Your picture looks exactly like my engine looked like, twice, trying them. I can tell you it wans't the cylinders, the second or the oil rings in my application because I changed the top ring and it ran perfect.

We never really figured out why or where the oil was coming from. I stand behind my previous post, get rid of them.

In my opinion if cylinders are scuffed rehone them,call Greg @ Tri City with your bore measurement and depth of ring lands and get a set of his rings.

You have to run more oil ring with them. I agree, get rid of them. No power there.

Why is there so much oil in the lifter valley?? Plugged (on purpose) drainback in block?

Are the heads really filling up with oil? Are the head oil returns blocked by the gasket?

Weird at a low rpm that the oil can't get back to pan.

I also noticed there's only oil in the two middle cylinders. Could this be a dual plane intake problem? You did say all plugs were wet though.

Was looking at picture this morning,is there not a drain hole in right rear corner of block?
that is a lot of oil still standing back there, I would say it would get fairly deep in there running and would have to be over the hump of main oil galley,if does'nt have return hole there I would put one,I know some of the older blocks don't have holes at front above timing chain,I would put them if it does'nt have,make them low enough oil can't stand.
I would have good drain holes at all four corners and plug ones between lifters,that will cut down on windage.this is'nt oiling cylinders but could contribute to oil pressure fluctuations you had.

You don't possibly have windage tray that is filling up with oil and rotating assm. is running in pool of oil and slinging at cylinders.

Paul,
On very back of block in lifter valley is a hole that from the factory had a oil separator (baffle) which pushes into that hole (approx ! 1/4 hole and then a 7/16 head bolt holding it in place. Then that hole ends up coming out behind block on outside, right behind dist. Is that hole plugged on the outside of your block or do you have vacum on it to try and get rid of windage pressure inside motor? If you have vac on it, without the oil separator (baffle) in place it will suck oil like crazy.

from what I can see in the pictures is the for a engine that only has only an hour of run time ,the oil is really black and that is showing combustion in the crank case and not letting the oil drain back because the pressure has to go some where , cant explain the standing oil in the valley other than a drain hole is covered ,, I would suspect the rings is problem one of 2 gmonde

Guys, the drain hole on that side is plugged to keep oil off the crank. (That was done long before I got the block.) The oil pressure issue went away when I changed the pump, I'm going to put the Schumann on an oil pump "dyno" when I get time. The oil looks black in the pics because it's green - Brad Penn.
Going to order a different top ring set this week and cross my fingers.
