I hate to say it but .....it sounds like a broken ring. Do a compression test and a leak down test.

Your situation sounds more serious than a dip stick or PCV valve. I first cranked mine up without crankcase ventilation and it blew a small amount out of the oil fill cap but nothing out of the dipstick. I added a PCV valve and two filtered breathers and there is no oil anywhere coming out. I'm not a professional builder so I am only sharing my current experience with you. Good luck and I hope it isn't too serious. ‘72 Charger, 5.9 Magnum, Tremec 5 spd., Pro-Touring ‘14 Big Horn, Quad Cab, 4x4, 1500

If the PCV valve is working and hooked up, and you're still building pressure in the crankcase (oil squirting out everywhere is the first clue) then your new rings didn't seat. You're going to be taking the engine down to replace them and hone the cylinders with the right stone for the rings you choose. Sorry, R.

Sorry, R. ......Another reason the rings my have not seated, they could be hung up (compressed) in the ring grooves and never expanded after you compressed them to install in their bores, happens sometimes with used pistons if the grooves weren't recut, or you have the wrong rings (thickness wise) one of those things you have to know/check during assembly

If it was set to factory gap then it could have broke the top of a piston. The KB ring groove being so close to the piston top makes them heat up faster then stock which in turn which causes them to bulge up and snap a chunk out. I have a 318 bored .030 over with 0 deck and 62cc heads and it never pushed oil out of the dipstick tube so you may have a serious problem, but I hope not! 7182392-KBbroke.jpg (41 downloads) Living with ALS help support the search for a cure Thanks http://web.alsa.org/site/TR/Walks/WesternPennsylvania?team_id=347781&pg=team&fr_id=12069

I had a local shop do my block work,dip and hone new cam bearings,the motor didnt needto be bored because it only had 20,000 miles on it when i bought it..the reason i tore it down was a broken roller lifter..I did the build and filed the ring gaps to the specs on the instructions that came with the k/b 107 pistons..the machine shop picked the rings for me,dont remember what brand they were..i drove the car maybe 15 miles to get the rings to seat,thats when i noticed the oil was coming out of the oil breather and dipstick tube,so i parked it..it idles fine fires right up every time,doesnt smoke wile at idle,but at high rpm's it smokes..

With 20,000 miles there is still gonna be some distortion near the top of the bore, might be very small but it will be there. Now you have swapped pistons and the KB 107 has a higher ring grooove than the old pistons because the compression height is higher, now your top ring is traveling past this distorted area of the bore and unseating loseing cylinder preasure (exacerbated by the very high dynamic compression), the only way to fix it is go back to the stock pistons/rings or bore it to get nice straight bores with new pistons and rings. You could just drive it like this and it may wear to a point it seals a little better but it will never quit entirely till it is fixed.

Still gotta seat the rings, which is part of what a break in does. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

I'd want a load on it, why are you thinking you would not want to load it? it turns the lifters/splashes them/lobes better and seats the rings live every 24 hour block of time like it's your last day on earth
