If you have that much crankcase pressor that your pushing the dip stick out YOU HAVE A PROBLEM. It is cheeper to fix it now than it is to burn a piston or break one and have to buy a new block. Yes the damage is already done but it can always get worse. I have seen it and repaired it. BE SMART save your self some money and fix it before it's too late.
i'll never argue with an engine builder, and i apprciate your input, thanks!. i know the only way i can truly know what is causing the exessive blow-by is to dismantle the motor. i'm in the beginning stages for an ls3, plan on using my current heads, i have a cam already picked out. i'm not sure if i will do anything this winter. the car can just sit in the garage, until i'm ready. i would love to do total seal gapless and maybe the srp professinal pistons, but i don't know if it's compatible with the rings and n20.

I my self haven't seen much gain using total seals with nos, I would use arkley & childes with an HTD top and break them in with 10w 30 conventional oil. We use a lot of nos on our pro mod and this is our ring of choice. If i can help just let me know

thanks! i'm just planning on keeping my street car somewhat robust that's all. i have read in engine master mag that the total seal rings hold their compression much longer than the conventional latest thinner rings. i like the idea that the motor can hold 180-190 psi for a long time. i have enough time to pick what i need.

how is the friction coefficient on those rings compared to a conventional ductile iron or stainless steel ring, can they be used for say 80kmi without premature wear?

I tune for as close to 12.0 as I can get. My cam only motor has lived through 2 seasons of 150 shots, and a season of 200+ shots and is still going with 132,xxx miles. I've had my hiccups and burned a valve once and a few sets of plugs.

the friction is close to the same as a stainless ring and will last well over 100k with a good tune.

thanks to both of you for the input. as stated many times throughout this forum,i'm aware the TUNE is key.
so the stainless are top choice?

well my tuner put the AFR 11.8 and the timing at 24* i am only putting a wet nx single nozzle 100 shot and my mods are in my signature. i dont know much about nitrous is that good or bad and i just dont want the white cloud to shot out of the exhaust when i spray. he knows what he is doing when it comes to tunning but i just want your guys info

i rather see 12.2 and 20 on 100.
just finished the compression test .
2,4,6,8,1,3 all gave an initial 150 and climbed to 210 on the 5th crank.
5,7 seemed just a hair lower and climbed to 195.
i used gloves, the engine was hot soaked, it got cooler by the time i got to the odd cylinders.
so, is max press. build up as good as initial { the first stroke}?
i also ckd. vaccum and it pulled a steady 15hg from the neck of the intake.
could it be that the dip stick "o" ring is a bit soft and the rings are worn out with bigger gaps?.
also the blow by was a bit more than blowing through a straw, with the pvc removed and intake ports capped. i have always used 5qts. instead of the 6. so maybe that's why i never see oil spewed out.
