You can try squirting some oil in the low ones and see if it improves compression reading-big increase means rings bad.No significant increase-valves

thats not fool proof, I did that to one of my other car, oil didn't change reading much on it, turns out the piston was melted on the top ringland.

won't give a good indication if you have broken piston or rings.

Once in awhile even I get Lucky ! Carb Cleaner, a piece of wire, and a blow gun, and the oil feed is clear ! Dropped the pan tonight and all looks well from the bottom too. New oil pump arrives tomorrow, i can button up the bottm, install new valve guide seals up top and I believe I will be good to go .

Thanks again for your help guys !

Mike

Sighhhhh

New Oil Pump, blew air all the way through the oil feed for the right side. Started it up a ton of oil on the left side, none on the right, yet the blue smoke is still comming out heavy on the left side exhaust. Head Gasket? Can't be guide seals if there is no oil up top?

helpppppppppppppppppppp

Mike: Do you know if the engine was apart in the recent past? There can be issues with cross drilled cams vs grooved ones. And as I understand it, there was more than one type of cam bearing used in the valve train feed position. Possibly you have a bearing that is installed incorrectly or does not match your cam application. Unfortunately, only a disassemble would determine that, if other solutions fail.

well all other solutions certainly are failing, I am going to make calls today and try and find a knowledgable y rebuilder in this area, and just have the engine done. I still don't understand how the right bank is smoking so much and still not getting oil up top?

Mike.  How do the spark plugs look?  Is there one that looks like it’s using more oil or has more color than the rest?  Your compression readings are too varied which points to the rings being at least part of the problem as far as the smoke goes.

 

As a trouble shoot for the lack of oil on the right side, you can put a restrictor in the left side so that more oil can be forced up to the other bank.  With the passages cleared, there is a good chance that the oil is taking the path of least resistance and just not making it to the right bank due to the left bank getting it all.
