Help!! Oil shooting out of the dipstick!
Ok guys.... I am very beat down. All this damn work... finally have everything together. Chevy 502 in my 22' Scarab... runs great! Sounds great!! Everything!
Take it out to the lake to do some tuning... It is running a little rich so I wanted to play with the timming a bit and possibly jet it down a little.
I start to bring her up to speed slowly... at 2000rpms it starts spraying oil out of the dipstick! NOW What??
Do a little more playing and it really does it anytime I put the engine under load (hole shot or higher RPM). The only thing I can think of is maybe the motor dosent have a windage tray? Yes it has a breather on the valve cover... it does it with or without the breather.
Ideas?? Please help guys!!

Re: Help!! Oil shooting out of the dipstick!
If oil is coming up through the dipstick, then the crankcase is pressurizing beyond what the breather can handle. You definitely have some kind of problem related to your pistons/rings/bores. I agree with the leakdown test. There isn't anything else that I can think of that would cause the oil to squirt out. How old is the engine? If it's new/rebuilt, then there is probably an assembly problem. If it's got some hours, then something is worn or broken. You might as well get ready to pull it and check it out before things get worse.
Good luck,
Rene

Only other thing would be if you 'way' overfilled it with oil. The crank will totally beat up the oil.
Ok, one more thing - if you don't have proper # or size of breathers or ventilation tubes, the dipstick will push out do to the excessive pressure.

Don't know if this will apply or not. I heard if you rebuild with chrome molly rings that they take a long time to seat. If the rings aren't seated it will blow by. Its up for debate.
