According to some OEM manufacturers that is an Acceptable amount of oil usage believe it or not!! But really if you don't have any leaks than it is getting burnt up. I would do a compression test and then check to make sure your valve seals are good and see what is up. Also check your plugs to see if they are oily.

Do you have aftermarket valve covers on it? If you do, almost ALL of them have either junk baffles or NO baffles at all, letting the PCV valve suck up oil that is tossed around from the rockers. I had the same problem, new engine, lots of oil usage. I have the tall Proform covers and the PCV valve sits down far enough that it vacuumed oil off the baffle. I installed 2 "0-rings" around the PCV valve to space it up some and the problem went away.

You need to look inside the cover and see if you actually do have a baffle in there. Some do NOT have anything! LOL Just pull the PCV valve and take a look inside.

Mine have a pretty good baffle, as cheap valve covers go, but they are a tad short and the PCV sat within a few thou of the baffle plate. I added two 0-rings that spaced the valve up about 1/8" and it seemed to help a lot.

If you have NO baffle at all, you need to either add some kind of one or change covers. You just can't beat stock! but with roller rockers, you need a taller cover, which usually don't have a good baffle system.

1/4" should be fine PROVIDING the baffle is keeping oil dropletts out of the inside of the baffle. What kind of covers are you using?

383 Stroker Using Oil

It is using a quart every 500 miles or so. The compression is 160 lbs in each cylinder. The spark plugs look really good. Doesn't smoke out of the exhaust. The oil pan is not leaking. No leaks at valve covers. I am running Dart heads and Dart valve covers. I am really baffled. Can someone help please?

Thanks/ Doug

Switch it to Mobil 1 synthetic oil.... I bet it fixes it.

Give it about 1,000 miles to show an improvement.
I have seen it stop oil consumption in about 10 engines.
Most of those were on Castrol GTX.

Absolutely do NOT put Lucas in it.

just saw your old thread from 2 1/2 months ago.....
