Anyone have trouble with rings seating, anyone use sealed power R9771035 plasma moly

[rugerbp]

Just wondering if anyone has used the Sealed Power,speed pro, federal mogul R9771035 plasma moly rings,, if so any trouble with them seating, about how long did it take for them to "fully" seat, i have about 300miles on my new 347 build, have a little bit of a problem with crankcase pressure, did the v/c breather thing helped out a bunch, now going back and putting in another PCV on drivers side v/c and an oil catch can, compression is 148-152#s on all cylinders, it drives good but lots of crankcase pressure and blue smoke out the back, #4 plug was wet with oil, that couldve been the bogging issue i had, got new autolite 25s gapped to 50 close to stock,, anyone have any thoughts/suggestions

How did you seat the rings?
you need to drive the engine kinda hard for the first 100 miles
or so to seat rings, you dont want to baby a new engine.

also, if they did not clock the ring gaps correctly you
may have two ring gaps lined with each other.
This would allow oil to get up in combustion chamber and
excessive crank case pressure.

I didnt build the engine completely myself, i had our mechanic/machine shop family friend build it he has a performance engine shop, does all our tractor pulling motors, hasnt ever made a mistake yet, im not babying it too much, i hammer down pretty hard on it most of the time, going to swap out plugs get this 2nd pcv in place and drive it see what happens

Nobody is perfect EVERYTIME and we all make mistakes

your compression test numbers look good though.
usually you'll see bad test on that cylinder if ring gaps are lined up.

yeah +1 on the not being perfect, i knew when i started this project it wasnt going to be one of those quick builds nothing ever is and you always spend twice if not three times as much time and money on it as you thought you might have, everythign seems like it is fine, got those new autolites, going to put em in tonight or tomorrow and see if htat helps plus goign back to a PCV system instead of breathers,,, think i have all my basis covered for sure now, so if it still bogs or acts stupid then i need to take to tuners and have em burn me a chip,, runnin 42lbers with 347 w/ 9.2:1 comp w/ edelbrock rpmII intake and 75mm TB w/ 80MM Pro-M and all the goodies to go with it

i was always under the impression that you were suposed to go easy on a new motor for the first 500 miles to break it in.... not the "break it in how your going to run it" methed.

i dont care what anyone says. dont have to beat on a fresh engine to properly break it in. the rings will fully seat within 15 minutes of idling. if they dont, they never will.

 

[rugerbp]

not really sure about that 15mins of idle stuff, never have had one seal that quick

It's not just the rings seating into the pistons, its the intial wear
pattern the rings make on the freshly honed cylinder walls
It takes some agressive but not constant rpm's to make those.

I've read several artcls that all say the same thing
"Drive a new engine hard to seat rings properly, with extended cool downs between"

check out this link, this guy is dead on with what others say.

I was told another method of seating piston rings. Drive the car in gear up to high RPM, and let the motor slow the car back down to 1500RPM or so.. repeat this process several times.

I did this with my motor, and they seated fine. I also did drive it hard right away. Just can't help myself..

I drove mine like I paid for it..slow and easy, varied RPM and ring seating was not a consideration. The rings should seat within a few minutes. Dyno results, fuel milage and oil consumption indicate the engine is very pleased with me. You can break it in any way you want....regardless of wht you do the rings will seat VERY quickly or they won't.

you need to put a load on the rings to push them against the cylinder walls.babying it will not seat them right.i run total seal rings drove the car up and down the mountian here that made a big difference.i have about 450 miles on it now and just put the turbo on it and not one problem

 

[rugerbp]

good advice thanks to all

I use the graphite power (recommended by ring manufacture) on the cylinder walls and install the piston and rings dry. The rings will seat within a few minutes of startup and I have never had an issue. Just another method to consider.

thats what ive always heard. if youve ever seen a nascar motor break in period its pretty neat. obviously they dont break those motors in for 500 miles but they get the rpms up and fluctuate the rpms for an hour or so and than do a dyno pull. but those engines are built by the best and they use the best of everything.

rings will not seal in 15 minutes, especially the chromoly rings. mine took close to 700 miles before it stopped using oil

the rings that probe recommends with their pistons seated within 20 minutes after initial startup on my 331. I had visual smoke from the tailpipes after starting but kept the RPMs from 1500-2500 for 10-15 minutes.

If compression is good check out a valve seal leaking. stranger things happen.
