Engine Stopped blowing oil mist. Ya got me!!!

Some of you may recall that I had a thread going trying to figure out why my 1600CL engine would blow oil mist out the intake air cover on a high speed long endurance run. I would get home and find a black oily soot on the tool box side cover and oil droplets on the front of the left saddlebag. We discussed every possible cause we could think of and I finally came to the conclusion it was normal ring wear since I had a 15 PSI pressure difference in the front cylinder when doing a wet/dry compression test (12 PSI back).
Well, it stopped doing it. I have been on several high speed runs lately and not a drop of oil on the bags or sooty deposits on the side cover. Before anyone asks...no, the crankcase oil level was not overfilled and yes, there is oil in the engine.

I don't know, maybe it's a Christmas miracle. Merry xmas to me!

Well I don't believe I would go digging around to find out. If it's not over filled, it's not empty and oil is circulating then I would just be happy.

You got it, brother! I was sweating an engine tear down for awhile. Like they say...if it's not broke don't fix it!

Yup, I am confident it was my advice that helped you "fix" the problem that went away by itself.

Well, not really, but am happy to hear the positive update. You keep riding that thing while some of us bundle up for snow. Enjoy, Bill!

Before you dismiss my comment, I worked as mechanic from marine thru motorcycle to John Deer. I have a college degree in Ag Science and when my instructor showed me 6 set of piston rings in 6 stages of break-in I was amazed to learn that engines are often RUINED at dealer start-up. The 5 minute idle after set-up is where the cylinders are glazed and rings never seat. Believe it or not. Then he showed me his secret. AJAX scrubbing powder, my G_D I didn't believe my eyes when he poured a half a cup into the intake of a $120,000 dollar John Deer tractor engine. Too much puttin around during build-transport-display-testdrive. Yet Yamaha told me to mark their rings on a camchain replacement and reinstall in exact location and take a straw full of AJAX and blow into the intake while on the bike stand to reset the rings. I usually do that now instead of buying new rings.

I had a volkswagen diesel that wouldn't stop running after I ran it floor boarded for ten minutes up a hill. The problem was oil build up in the valve cover that got sucked down the intake valve stem powering the diesel engine without need for diesel fuel. I had to stop it in gear. It's called a runnaway. The culprit was a head gasket that had a too small of a drain back hole punched into it that restricted the oils return to the oil pan. I have a Polaris 325cc currently that does the oil build up in the cylinder head also if I drive the shit out of it. So I put a vent tube down under the engine to prevent oil in my air intake housing. Some day (doubtful) if I ever tear it down I will address the issue.

Also ring end gaps can some times rotate around to the same spot on the piston and allow pressure to get to the crankcase. I think that is why TOTAL SEAL rings came into being and if I remember right that is why I only used TOTAL SEAL on horizontaly opposed engines cause the weight of the uncut side would over time jiggle the end gaps to the top and cause blow-by.

Hey blaster - riddle me this. I am not an expert so a real question here. On "Twist the Throttle" every factory tour I remember and CERTAINLY the Kawasaki episode showed and said they do a factory test on each bike (though they only show sport bikes).

They run them on the dyno pretty hard and the results are paired with the serial number so each bike has a history ... bla bla bla.

If thecase for every bike, would that take care of the dealer start you described?

Is your penchant for using AJAX the reason your handle is Blaster?

I'll have to look into that.

It ain't about where you live; it's about how you live. So, ride to live, Bruh.

I work for an OEM that uses lots of engines. I can assure you the engine has time on it before it gets to the dealer. If there is a problem with the engine it's not 5 minutes of idle time at the dealer that did it...and we absolutely do NOT authorize nor advocate intentionally "dusting" the engine to try to get the rings to seat.

Ajax is made from limestone, which is heated and then mixed with water. Carbon dioxide is added and produces calcium carbonate, which is then dehydrated to form a powder.




pretty sure i dont want limestone.... much less any dust in my cyclinders!!!
