i have aproblem with oil blowing out of breathers on left valve cover. not a whole lot, but enough to get firewall wet, and get on header and smoke some. ive never had this problem before. i run a 355 chevy with hyd. cam, duble hump heads, flat tops. the oil pan is stock, but with a windage tray. we run 6 quarts of val. 20/50 racing oil, and delco pf1218 filter. this happened in 25 lap feature on 3rd mile dirt track last sat. nite. why? is there something wrong? please help! thanks in advance, neil (770)740-1532 jnrtlr@mindspring.com also, oil psi has never been low enough to have idiot lite come on.

This is caused by air getting past your piston rings. It is something to warn you that your engine innards are in need of attention.

Do you have any oil on the plugs,are they wet at all?
Any smoke exiting the exhaust?
Broken ring on a piston....maybe?
If you can...run a compression check on the cylinders.

A little blow by will happen,but this may be more.

Wrap the breathers with rags or old socks...I've a prob with this regardless if the eng is new or old...We are blowing a little oil with total seal rings and always have with this eng although it has 40 nights on it now...due for a rebuild..

Every engine i had did that,when your turning alot of rpms its going to sling oil no matter what condition your motors in.I got some rubber hose and extended my breathers to the firewall,solved the problem.

If you run a quart over on a stock pan it will do that.

I've thought about this a day or so and remember why our engines do this. We don't run oil restrictors thus we flood the rocker chamber with oil. This is one reason to blow oil out of the breathers...

ss that scotch brite will break down over time then you have abrasive material in your oil not a good idea try some old socks in the tubes still breathes and catches the oil or we also do the old radiator hose trick works well

Zero,someone on here gave me the idea to use perforated drain tile,the type used around foundations etc.Buy a 10 foot section and cut them so they fit into the cell standing up,the only tricky part is where the pickup tube goes,i also went a bit farther and tied them all together with plastic ties,all cost together$2.50.

we bought some of the perforated scrub pads at the supermarket that look like copper, but there used to scrub pots and pabs in the kitchen. let everone know how it works.

[the copper pads did the trick for us and
we also pulled a little out and over the tube edges to keep them secure as we slid the breathers on/ we cut them in half too/ read circle track articles about oil problems
about 6 months ago I think.
E-mail me at bobaluuu@aol.com about the car
we talked about earlier neal. I'm gonna part it out I think.
