wow! extreme oil leak!

[boosted86]

ok heres what happen... ive been having this monstrocity of a leak for quite some time now and im also expeirncing some exssesive crankcase pressure(my dip stick shoots out and i even get oil squirts) well anyway i seem to be getting this extreme leaks after boost(when i say extreme i mean 10 drops per 5 sec..i counted) so i changed out my main front and cam seals< did a compression test 155 across the board( 6 bolt swap) so im perrty sure im not getting blow buy. what else could it be ,,,thanks for the help

From what part of the engine is the leak coming from? Any other symptoms? To fix this one I would try and find the source of your crank case pressure. It could be that the pressure is forcing oil out of a seal (oil pan, front and rear mains etc). More info would be very helpful.--Jon

thats the ting i cant put my thumb on it! changed my pcv valve, did comp test to chech my rings for blowby, and nothing where else can i be getting it from?

Change your pcv valve, as it sometimes causes the dipstick to pop out. Check to find out where the oil is leaking from, either by getting that UV dye, or just cleaning your motor and then checking it in a day or two.

PCV Valves are notorious for being bad even when new. I would change it again and see if that helps. Depending on where the leak is coming from these could be seperate problems, so you need to find the location of the leak and change whatever gaskets need it as well. Good Luck!

You can actually test the PCV to see if it is bad instead of purchasing a new one. I know they are not that expesive but if that is not your problem and you keep buying them it could get expensive. I do not know what pressure these are supposed to open at but all a PCV is is a check valve. It will open one way and not the other. If the valve is not functioning properly it will either remain open (excessive oil in your intake) or not open (excessive crank case pressure). I know this is just preventative maintanence 101 but IMO you would be better served checking the old one before you replace it. I would also check your turbo. If you have a new PCV and good compression, then a bad turbo is the only other thing I can think of that would cause excessive crank case pressure. Especially consdering that the problem only occurs under boost.

Step one: go to pep boys and buy two or three cans of foamy engine bright.

Step two: let your car cool down and jack up the front end and put on jack stands.

Step three: spray the shit out of the whole under side of your engine bay and engine whereever you see oil. Any ####ing dirt anything! spray it with the engine degreaser. Now it says let sit for 15min, well this stuff destory aluminum so let it sit for like 5 min and then get your hose and spray the hell out of anywhere you sprayed the degreaser.

You will now have a huge oil streak running down your driveway/street/where ever. so get out some more degreaser spray that area and his it with the hose again. start your car again, drive around park and let idle. Jack the car up agian and look for oil. That will tell you where it is comming from.

not sure if it would have anything to do with anything....but have you checked your oil pressure sending unit? I have a friend that had a busted one (he didn't realize it) and ended up blowing seals on his car.

I don't think that is the problem here and I also do not think that it was the direct cause of your friends car blowing seals. All that would happen with a busted OPSU is that your gauge does not work and you might get a leak that accompanies the failed unit. The OPSU does not control the pressure of the oil or the amount of crankcase pressure so it cannot be the cause of bad seals. It could lead to bad seals because you are not able to see what your oil pressure is though. Has your friend fixed his problem yet? If he only replaced the OPSU then he might still have a problem elsewhere. Oil leaks are serious problems that need to be fixed as soon as possible. The leak may be small right now but that could change in a week or just a few seconds.

Today at the shop we were trying to track done a leak on an F250 and found out just how quick a leak could change. We located where the leak was originating from and started to clean off some of the dirt that had collected around the fitting that was leaking. As soon as the scraper hit the fitting it fell out and about four quarts of oil drained out. If that fitting had come off while the truck was on the road we would be installing a new engine insteado of just replacing an oil temp sensor.

One thing that hasn't been mentioned yet on here is your crankcase ventilation tube. The little hose that runs from your crankcase to the intake to ventilate pressure could possibly be the cause. Take the hose off and see if it's clogged. Then take your valve cover off and inspect the port that the hose runs to. Also, just to be sure, take your PCV off and blow into it. Like said earlier, it will let air flow one way and not the other.
