when you say new piston rings did you rebuild the engine or did you just hone and put a new set of rings, ive seen several times people hone the cylinders out and remove to much material to where the engine has blow by because the rings aren't sealing properly because the bore is a tad to large not saying you did that im just saying ive seen that in the past
First off how many miles are on it? Second what type of oil is used as well as weight? Lastly was the bores scrubbed clean with a heavy duty cleaner and stiff bristle brush before the block was assembled?
Many times someone gets a block back from the machine shop. They give the block a standard wash job before assembly not realizing that's not good enough. When the block is honed the bores are impregnated with the grit that comes off the hone stones. Unless the bores are scrubbed with heavy duty cleaner and brush this grit remains in the bore. The engine is assembled and the piston rings and oil break this crap loose from the bores. The grit causes rapid wear on the rings robbing them of more than half of there usable life span.
Also I should ask what type of rings were used? Cast Iron? Moly coated?
Are you certain the ring was installed right side up? Most rings have a mark on them to indicate which side is up, if they are installed upside down high blowby results. Which pistons were used?
i'm not sure about what pistons and rings were used, but i cleaned everything real well(as best i could anyway) , and after assembly i filled it up with 5 gallons of conventional 10w-30 pennzoil with the comp cams additive for my new cam
there is no smoke out the tail pipe indicating oil or anything, clean as a whistle, even on hard acceleration and deceleration
One solution would be to get a new 14" air filter assembly with PVC nipple in the base or if yours has the knock out just get the nipple. Then get a breather cap for the valve cover that has a nipple on it. Install a clear hose from the air filter base to the breather cap. Another thing to do is pull the right side valve cover and see if there is a baffle under the cover where the breather cap fits. If it does not have a baffle attached to the valve cover try these from Summit Racing. Summit Racing SUM-G3413 - Summit Racing® Valve Cover Grommets - Overview - SummitRacing.com
