350 Oil Burning

May be leaking at the valve guides. Were the heads done? Every time I have done a 350 I have added Ford cup style seals on the valve stems, in addition to the GM seals. Easy to pop the valve covers and do this now. Just make sure you pressurize the cylinder before removing the locks or you will drop a valve and have to remove the head.

How long Have you run this ENGINE ? 100, 200, 500 miles ? long enough to SEAT the Rings ?

We take it u have BLOW BY... SMOKE comming out of the VAVLE covers.. Not out of The EXHAUST PIPE .??

Who Rebuilt the engine..? No warentee ? if it is take it to the person who Charged u for the Rebuild .

a Ring may have broken when they put the piston into the CYCLINDER .

Ring GAPS not Staggered !

Too light of oil

thet> The rings are on the pistons right, and spark plugs were oiled. I have

When you have one PCV valve in, is the other valve cover vented or blocked off? It needs to be vented other wise you'll suck crankcase vapors through the motor.

I'll add, you'll suck oil through the motor with the crankcase vapors.

A few questions, what is your oil consumption rate? Next, did you break engin in with SYN oil? (this is not wise to do) Also, how did you break it in after rebuild?

2 questions..............

What happens if you remove BOTH pcv's?

What is the "actual" oil consumption of the engine when only the "drivers side pcv valve" is removed, and the "smoke" condition doesn't exist ??

Okay, I do not consider a quart every 2500 miles a problem. The reason for this is i like to see a engine use a quart of oil every 3000 miles or so because it helps keep upper cylinder lubed. I have a engine that has been "burning" a quart of oil every 3000 to 3500 miles for over 10 years and it has not changed and it has over 180K miles on it now. You might try 10w30 in warmer weather because a 5w30 oil tends to increase consumption sometimes in warmer weather. SYN oil can also increase consumption sometimes too.

The part about the oil burning stopping is wrong. I had the motor pretty warm after getting stuck, and at idle it puffed out smoke of the exhaust. I hook up the other pcv valve and a few minutes its stopped burning

OK.....now i'm pissed.

You're wasting our time by posting misleading and false diagnostic test results causing us now backtrack up the diagnostic tree and start from scratch.

so....let's start ALL OVER!!!!!!!!! here we go.....based on your latest diagnostic post........ . . (please note quote marks) :)

1) "the part about the oil burning stopping is wrong"

2) "had the motor pretty warm after getting stuck"

3) "at idle it puffed out smoke"

4) "and a few minutes it stopped burning"

now.....instead you make'n me smoke up all my homegrown to keep from pull'n my hair out.........

let's jest go with this aye........

pull the freek'n valve covers off you lazy bum and replace the guide seals before you dare make one more repost.

then....and only then.......IF it still smokes....... do a repost, and i'll tell you to yank the pistons to ck the rings.

I was wondering why nobody else mentioned the seals.....

And I'll repeat, double seal them. Use the cup seals as well as the GM seals. On all of the valve stems.

burning stopping is wrong. I had the motor

Hey, asshole, this is not the way to get help.
