Burning Oil On Rebuilt Engine
Burning Oil On Rebuilt Engine
OK guys, Engine was fully rebuilt with EVERYTHING NEW and properly sealed no leaks, no smoke on low or high revs, nothing to give a hint you can just smell the oil inside the car after 15 minutes of engine running. I'll say again every seal and gasket was brand new when rebuilt and even the valves seals are new. I'm using 20w 50 grade oil mainly because I'm in the Caribbean and is always hot down here and secondly because the engine runs a lot for extended periods of time. But trying to figure out what is wrong? Any heads up?

Re: Burning Oil On Rebuilt Engine
A quart every two weeks.......... I'm thinking maybe one of the valve seals........

Re: Burning Oil On Rebuilt Engine
Is this a rebored engine with new oversized pistons ?
Re: Burning Oil On Rebuilt Engine
no is got the Std. size pistons one the block only received a honing. And the thing is its only used 2-3 times a week. And you can just smell the oil cooking itself....... but it's not visible.
Re: Burning Oil On Rebuilt Engine
How much is 2 weeks??????????????????????????????????????????????????????
Also, it is never from valve stem seals!

Re: Burning Oil On Rebuilt Engine
Did you rebuild it or did you get it done professionally?
How was it honed? How was it measured? Were the pistons and bores in spec?
Are you positive the oil rings were installed properly? It's is not too hard to mess them up.

if it isn't leaking... and it isn't being sucked down a valve stem.... it has to be the oil control rings

Re: Burning Oil On Rebuilt Engine
Again, HOW many miles, kilometers or engine hours are 2 weeks?

Re: Burning Oil On Rebuilt Engine
aprox. 10 engine hours every two weeks......the funny thing is that it started over month 1/2 ago at first it was fine
this picture was taken during the rebuild process...what do you guys think? they oem blacktop pistons and the rings were new...... is it possible the c/r could bust them? this engine is lil bit over 13 can't remember right know and yes it uses 100 octane gas and the engine runs a little rich

Re: Burning Oil On Rebuilt Engine
and if it was the rings I should be able to see the smoke???
Re: Burning Oil On Rebuilt Engine
was a torque/hone plate used when it was honed?

honestly I was not there that day so I can't confirm it. I'll just go ahead and buy new rings if that's the case...... The rings were installed properly that I'm sure. What went wrong I would like to know since I'm yet to know all their is about these engines.
Re: Burning Oil On Rebuilt Engine
What's the compression?
Any of the plugs look oiled or all equal?
No secrets. There's zero difference, especially in this area, between it and any other internal combustion engine, diesels included, Wankels excluded.
Oil rings are difficult to F'up, so I'm guessing that a 2nd ring is broken or upside down.
Forget the hone plate stuff.
Good luck.

Re: Burning Oil On Rebuilt Engine
I think the piston rings are not seated properly yet. Try using straight SAE 30 weight oil only for 3000 miles and it should do the trick. Do not use synthetic during this break-in period.
