LOL crazy smokescreen at WOT

[dkbmxer002]

how the fuck did you put that much oil in? and the smoke i saw in your video looked like it could be oil...


it was probably blowing all through your pcv system. hopefully not through your rings...

[rcfanatic]

Stupid mistake. Somehow I mistakened the amount of coolant to be the amount for oil.

[call me jack]

how did you manage to fill your oil that high? did you think you were changing the oil in your 18 wheeler?

[e30lov]

im going to say that is a coolant/oil mixture and that your headgasket is fried

New head gasket 2 weeks ago. Doubt it is shot. Oil color is normal and coolant color is normal. Temperature reads dead center when warm.

Does it run okay? That much oil can feasibly be whipped up by the crank and overcoat the cylinder walls and force oil into the combustion chamber. I was a half quart to 3/4 quart over full on my M42 when I put the turbo on it and it smokescreened, but not near that bad....and it ran like shit because cylinder number one oil fouled. run it like that too long and apparently you can hydrolock it and break things....

this is exactly whats happening. overcoating. Too much oil is loading up the oil ring on the pistons and preventing it from controlling the flow of oil. When you bag it, engine revs higher= more oil flicks and you get smoke.

btw its super hard on your engine to run with too much oil. imagine your crankshaft completely covered in oil trying to spin. fast swimmers swim atop the water... not fully submerged. same idea here

It ran OK, but seemed to suffer on the low end and did smoke some when I got on it good. It's hard to say because I just changed to a milled 885 cylinder head and running open headers, so it was difficult to tell what it *should* feel like.

The video I posted was the first and only time it had smoked that bad.

Anyway, I drained a little under 3 qts out of it this morning and it runs stronger now with no signs of smoke.

[ak-]

lol drained 3 quarts? Hahaha

[mr.vang]

i think you redline it pretty bad and there goes your H/G

Maybe, but it seems like it would still be burning oil pretty bad if the gasket failed between an oil channel and one of the combustion chambers. Guess I could have a compression test done. Been wanting to anyway

[rcfanatic]

The more think about it, I think when I dropped it into second and held it steady for several seconds, the vacuum created by the high rpm probably pulled a lot of oil through the pipe that connects the crankcase to the intake manifold (I believe this is part of the PCV system).

So during this time the cylinders would have been loading up with oil and then when I hit full throttle it rapidly burned all of that oil, creating the plume.

this happend to me on the way to beamer fest.....you blowing oil out on you exhaust from the oil pan

[rcfanatic]

Man this motor is awesome. After draining back to normal levels and seafoaming the intake she pulls like a motherfucker! No more smoking. Can't wait to get these eta exhaust manifolds off and get a real exhaust with o2 sensor on.. then the 4.10.. she's gonna boogie!!
