Oil coming out of dip stick

Check into running a bigger breather? Did not give us details on the motor, but may need to run another breather if needed..

I usually always run a PCV valve on both covers if I can, but all of my freinds seem to be able to run just 1 and be fine.

Had the same thing happen to my small block buick after 4000rpm. If a couple of PCV's dont solve the issue, you have a tired motor, and its time for a rebuild. Make sure the hose from PCV to carb is an adequate diameter, and free of obstruction. You need 3/8" minimum. If using T fittings, make sure they are good sized. Many of them pinch down to about 1/4" which is too small.

A couple of questions come to mind.
1) Is your dipstick tube shorter than it should be?
2) Are you overfilling you engine with oil?

1.My dipstick is correct stock height
2.i put 5qts of oil
I do have a T on it its connected with the hose that comes from the brake booster.When i changed the breather and hose i saw some oil in the hose.

I had a 77 chevelle that i put a 283 in. It would do the same thing. even tho the bottom end was punched .030 over and all brand new, i found out i had a bad compression ring on # 5.

I hope its not tired that will mess up my plans for this winter.

It could be that you have insufficient or clogged breathers on your valve covers.
This happened to my modified small block during high speed runs at the track.

which breathers do you recommend to use the one i have i bought from pepboys.

Forgot to ask if it was a compression ring will the exhaust blow smoke or not.

Sorry i didn't but its on my signature.

depending on how warn out your rings are,
you will notice some blue smoke coming from your exhaust, and smell burnt oil

but it is possible for oil rings to be okay and the compression ring to go bad, where you will notice blowby and high crank pressure, but there won't be noticeable oil consumption

... my motor is a good example of this
My engine has excessive blow-by (due to loose bore-to-ring clearance, and high compression), it smokes like a chimney, but doesn't consume oil

Well my car doesn't blow no smoke at all not on start up or running.

do a compression test, I think one or two of your cylinders are down, or your crank ventilation system is clogged.

it is possible to have bad rings, without oil burning... it just means your compression ring is letting combustion gases past into the crank case, but oil rings are still doing their job.

start with a compression test, it will tell you if all your cylinders are consistent. If one or two seem off, then it's time for a leakdown test, which will accurately tell you where the compression is being lost (my guess is bad rings at least in 1 cylinder)

Thanks that's what I'm planning on having done.
