if the rings was on upside down it would be the same as wore out rings and you would find it by doing a comp. check. may not have enough comp. to start the motor.

the process of elimination....no?..and why then do race engines employe windage trays as well as dry sump systems....to elimanate the possibilty of sloshed oil producing pressure as well as drag on the reciprocating assembly.....its all good mike!....and this has been a very very good thread .....now good buddy, what do you think of my last question?.... [/QUOTE


race cars do it for hp, if you can get you crankshaft out of the oil in the pan then thats good for a lot of hp. as far as the oil getting by the rings from the bottom side if the rings was that bad you would have a lot more to worry about that oil getting on top of the piston. it wouldnt have enough power to get up enough rpm to slosh the oil up there. youer doing better.

Hi again everyone.
This thread is gettin' real interesting! Someone mentioned upside down rings? It may have been 10 years ago, but I clearly remember the rings being installed with the "dimples" in the up position. I believe that this is the correct proceedure, yes?
Also, the PCV valve is brand new with still the smoke. I plan to get a comp. checker gauge at the parts store this week. I am very anxious to see the readings, but if my rings are indeed "stuck", then could the readings be accurate? We'll see! I am very intersted in everyones comments, and I am learning much from you all

if they are stuck, then is gonna show that the rings are bad, at that point you want know if they are stuck or wore out. youll have to decide that at that time. if they are stuck i dont know how you would unstick them without pulling the pistons out of the block. somebody may know but i dont think so. if they are stuck it would be in the land grove and i dont know how you could get anything in there to unstick it. sounds like you got a plenty oil in there now so oil wont help. do a good wet/ dry comp check and lets see what you have.

I would like to add that if there is already oil in the cylinders from oil consumption that the compression test will have little validity! It WILL be abnormally high possibley covering up a problem gone unnoticed.....

As to the ring being installed upside down...easiest way to tell is pull the breathers from the engine and let it run....rings installed upside down will have excessive blowby and therefore will be pouring out the covers ( like an indian sending a smoke signal)

Also as for the Pcv issue... lets not forget the other had of the ventalation....so it's not a plugged pcv and it's new but.... if the engine is shut and no return air the pcv will have a "negative" effect and suck oil thru the pcv valve.....

This is why I suggested the Q-tip trick on the pcv hose at the carb base as well as the line from the modulator valve ( for an auto tranny).....

From my personal experience some problems are hard to diagnose and it takes a compitant person to do such...And any of you that have ever taken your vehical to the "dealership" for service know that there aren't that many around.....

I agree alot of people have given some very good/great advice....

I personally am not conserned with the bore/hone job as far as the oil situation.....I once had a 265 come in from RHS that was bored .060 and had standard pistons in it....how it lived I don't know but it did....it used no oil but had shavings in the pan you wouldn't believe..... I have seen a thousand times engines come for a freshening that are .040 with .030 rings and they live....course I send them back in the "right" condidtion....
