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

Re: Fresh rebuild, oil everywhere
 

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.

Re: Fresh rebuild, oil everywhere
 

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

Re: Fresh rebuild, oil everywhere
 

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.

Unplug that hole!

Re: Fresh rebuild, oil everywhere
 

Paul did you get the oiling problem fixed.?

Re: Fresh rebuild, oil everywhere
 

Looks like some may have put the oil rings upside down. For the best results a plate hone is a must if your looking to achieve good ring seal.

GM blocks seem pretty frail and the cylinders will distort once the head is bolted on.

The cylinder show a lot of scuffing either debris or to tight of a fit or both.

I've been holding off posting on this until I had it fixed, so....
If anyone out there is considering gapless rings, DON'T DO IT!!!
On the advice of Mike Taylor, I got in touch with Gregg Luneack at Tri City Competition to talk about rings. It seems this is a very common issue with the Total Seal Gapless pieces of she-ite. Gregg hooked me up with a set of his Race Rings...he mailed them Saturday, I had them Monday morning. I got the thing back together and fired it up tonight, and whaddya know! No smoke!
I can't believe Total Seal continues to sell this garbage. I have not contacted them yet, but I will tomorrow. $350 down the toilet, not to mention countless hours of work and stress, plus missing a month of racing...I'm pissed.
And Ed, I opened up the hole like you said! Thanks to everyone for the info. We'll find out this weekend how much faster it is than last year.
