Sucking oil down
05/30/08 at 21:52:05

I can ride 50 miles & need to top off the oil. It'as not time to change it, but I am gonna, just to see if I have enough metal in the crank case to cast another engine with. The air filter is clean. I cant think of anything that would just make it suck oil, except I have ridden it hard, but I did break it in according to the rules. I have been good about keeping the oil changed, maybe more often would have been better. Its running great, no banging & clattering.
Clues?

Then I washed it good and used a pint in about a week. I hope the crud on the engine wasn't all that was holding my oil in. I'm watching it closely right now.

It sooots the brake arm up pretty quick, BUT, I just cant seem to keep an eye on it & run it. I need to get the kid to follow me, or me follow her. I can burn a pint in 2 days I Think, I am a little skeert, because I may have hurt it, because I had pulled the choke to the first cluick, & I thought I shoved the knob back in, but, when I was almost home I realized it was still at 1/2 & I had been riding hard for an hour or more..seems like the oil issue has been a bigger deal since, BUT, I have managed a higher top end since the high speed oil use started & after that day.

If it soots up that badly I would say you are burning rather than leaking. Now the question is where from. Have some one with a keen eye follow you. If you burn a consistant blue or burn more on hard acceleration I would check your compression. You may need new rings or your oil ring could be broke or wore out. I believe savage greg had an issue that his rings sacked out and his was so bad it would barely run. This is oil coming up from below the piston.

If it only smokes at start up and/or on slamming the thottle shut at high rpms then you have valve guides/seals leaking and it is coming down from above in the head. When you slam the throttle shut you create vacuum cycles and leaky valve guides/seals will allow the oil to be sucked down out of the head.

good luck!

I have noted in the past that when its time for an oil change, it starts using oil. I changed it last nite, so, Ill watch it & see whats up.The basics you laid out is what I was after, Smokin Blue, thanks.

It runs good. I saw 94 on the speedo last week. I kinda think its running better than its ever run. THAT bugs me. I used to fly model planes, & when an engine peaked, it was just a few flights from needing a rebuild..

Yah...two strokes always run the best right before they seize!! (I guess that's what makes the ragged edges such a fun place)

15-40 rotella. 150 main, stock pilot, Trapp with 14 disks.

I rode the snot out of it , now I need to look at the oil. I kinda forgot about the oil usage at the end of the life of it. The oil gets sheered in the gears & as the shafts rotate, shortening the physical length of the hydrocarbon chain.It seems to "Go Away" fast after I get 2,000 miles or so on an oil change.

The onset of oil usage after being beat & crushed & scorched is an indicator. Time for fresh oil. Next time, Ill be more attentive. I dont think its running thru now. I do thik I'll do what Old Feller does & get some serious magnets working on it.
After I dumped the oil from the gallon catch pan, I took some pretty stout little magnets, that I had removed from a dead Sonic Care toothbrush, & held them just over, not in, the oil, close to a dark area. I moved them slowly & when I lifted them away & looked, there was a tiny trail of dark matter that had been attracted to the magnets. TINY stuff, so small there was no flat surface that would reflect a glint. I bel;ieve OF's idea is well worth the expense & hassle of installing.

TIA, O.F.
