Curantly my car has a stroker 493 that only gets to 165 in cool 45 deg weather. In the hot days of summer she runs 175 unless driven long distance at highway speeds of 60 to 70 mph then i have seen 195. She is using some oil and i don't have a valley tin . I am using the Indy valley cover . Last summer pulled the intake and it was full of oil . Not sure where it was coming from i thought it might be the Mopar Performance valve covers because the baffles are not that great in side the cast aluminum covers . I went so far as to make my own baffles to try get less oil sucked in through the pcv valve. running a MP breather on one side and pcv on the other. What would be my next step ? She seems to be using about a quart every 50 to 100 miles but does not foul plugs weird. runs good and has great power . Any ideas? 1969 Dodge Charger 1969 Dodge Superbee

Hook up some exhaust evacs and run it like that some time and then see if your intake still gets contaminated with oil????

Already did the leak down test less then 5% across the board. compression is on the high side like 200 psi but i think because of oil in the cylinders. 1969 Dodge Charger 1969 Dodge Superbee

She seems to be using about a quart every 50 to 100 miles but does not foul plugs weird. runs good and has great power . Any ideas? Start by running it at idle. With the PCV hooked up, remove the breather on the other valve cover and plug the hole with your hand / finger. You should feel a slight vacuum. If not and you feel pressure, the PCV is not working or you have an excessive amount of blow-by. Also look at the inside of the PCV hose. If it is wet with oil, it may not be shielded proper with those valve covers of blow-by issue again. Only other way oil can get in to the intake runners ( "intake full of oil" )is a bad seal between the heads and intake manifold. You could also try running it without the PCV ( vent both sides ) and see if your oil consumption goes away. Don't think cold engine operating temp has much to do with above - not a qt every 100 miles anyway. Fastest 300

I think this might be the cause of my oil burning issues . I have read that these do not belong on a street car , ordered comp cams viton pc seals . going to try them. Guides on the two i have checked so far are Tight like less than 2thou. I will keep posting what i find. Need to send the push rods back to get shorten found them to be .130 to long. Smith Bros said they can shorten for $3.50 a rod . those guys are great! So its going to be a while until i get this thing back together. 1969 Dodge Charger 1969 Dodge Superbee

I know motors w/ no valve seals at all that don't use that much oil. I'd get rid of the pcv valve, just run rbeathers on the valve covers and try again.

Not trying to be a wise guy Crizila but how could the oil from the pcv valve in the valve cover going either to the carb or a fitting in the intake manifold via a hose be affected by the seal between the manifold and the heads on a bb with a valley cover? If the oil were introduced into the hose by blowby or getting sucked past the baffles it would get directly into the top of the manifold before it ever came in contact down where the heads and the manifold are sealed would they not???

Mike His original post stated "intake full of oil". The objective of the PCV system is to eliminate any cranking venting to the atmosphere. If the PCV valve is working correctly, it should be closed at idle. Above idle, it will open a small amount and introduce a vacuum to the crank case. The PCV hose usually gets its vacuum from the carb base or there abouts. If the PCV valve in the valve cover is not working correctly, not shielded properly from oil splash, or there is excessive engine blow-by, oil will travel down the PCV hose and be introduced in to the intake manifold directly under the carb - and you will have oil in the intake manifold. After market valve covers can often create this problem if they do not shield the PCV valve from oil splash. Only way oil can really get in to the runners on a big block. Fastest 300

Or you have a puddle on the driveway. I've experienced oil pressure idiot light switches that leaked like crazy, but the mess was easy to spot. Also had an oil flood inside the car when the copper line to the oil gauge broke at the gauge Paul

Wise had a great idea to prove or disprove it being the PCV , put a clear fuel filter in the line and see if it gets filled with oil quickly ???
