Oil loss in my red 7m na

burping your rad is a great idea don't get me wrong.. but its not going to sufficiently ruin anything in a matter of moments if there is an air bubble or two trapped in there.. and they will eventually make their way out anyhow.

No I did the valve covers, front crank seal, timing belt. No internal rebuild. I am not blowing blue smoke except after a long coast down a 1 mile hill with it in gear and only for an instant after during take off. I don't have a Turbo or a blown head gasket that test was already done. Drove it to town last night after burping it with the AC on high about 16 miles and it did not overheat after burping. Losing oil from the rear crank seal I think. Probably do need new valve seals though. No pools or drips of oil on my driveway but the rear trans has oil all over it. The plugs would show oil fouling if I was burning a lot of oil correct?

yeah true if it was burnin oil you would have a lot of shit on the plugs. how much dose it burn again. im in alganquin park on holidays =D

No blue smoke exept maybe a bit at times runs great, not sure how much oil I am burning, or if I am losing it out the rear main seal. I was 3 quarts low as I said. I will hit the tripometer and see how many miles I get before I lose a quart. Bout all I can do short of dropping the trans. Been reading seems like a real pain in the ass to drop the oil pan, perhaps I am leaking there. Not sure what the deal is. I have a real wet trans though. Probably the rear seal or oil pan gasket maybe the drain plug. Gonna go to town soon. Will look for drips under the car.

Last time I had alot of oil on my tranny I was from leaking oil from my valve covers/3rd cylinder head cover. It found it's way down the back of the engine and onto the bellhousing, causing some nice long streaks of oil down the length of the transmission from driving the car.

It seems to me that if you're leaking a substantial amount of oil from your pan gasket or drain plug, which 3 qts is definitely substantial, you would definitely see the oil on the ground.

The rear main seal is a possibility, have you had a slipping clutch? Many rear main seal leaks allow oil to get on the clutch, causing it to slip

i would probably inspect the #3 valve cover gasket. but if that was the case he would defiantly see pooling in the galley.

and if your burping your car every 5 minutes.. were are you sucking all this air into from? perhaps you have a cracked rad.

valve stems usually present their problems at start up.. "usually"
