Does Running to cool of operating temps hurt engine's in any way? 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?

The heads are Indy SR They were bowl ported and gasket matched nothing major. Any way to check valve seals with a bore scope camera? 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.

I run just breathers on my 6 yr old motor and used no oil at all in 1500 miles at Drag Week
some say the evac system doesnt work with an exhaust

Up date Pulled a couple of valve springs off , My Indy heads have Teflon PC seals on them. They are real Hard. 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.

I seriously doubt the valve seals are the problem. 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.

I went with baffled breather grommets on my engine. I just run breathers but they reduced oil leaks through and around the breathers down to hardly anything now. Another problem area is the dipstick tube.
Mopar to the bone!!!

" 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" How would this happen with a Indy Valley pan on a BB??? Mike Oil coming in through the PCV hose." 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???

This sure sounds like you have a leak to me Are you sure it's not smoking like a mosquito fogger? Using that much oil it should be. 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

Well for 32 bucks valve seals seam worth a try. If its not the seals then something must of gone wrong with the rings break in or the pcv is sucking in a lot of oil.

GEZ! Why don't you check out the PCV first??? No $, little effort, easy check?????
He did but the finding seems inconclusive. 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 ???
He's been chasing this problem since last summer .
