PCV Question

[Kuban]

Has anyone ever had the problem of excessive amounts of oil flowing through the pcv system, recircing into the intake? I had a catch can on my car and it was about half full in 2-3 weeks. I cant possibly see what would be THROWING oil into that area of the valve cover. I have a few ideas im going to mess with and see where i end up. But if anyone knows what would be causing this i would REALLY appreciate it. Its been an aggrivating issue for me. I should also note the oil is like milky and white. Now i know theres no water getting into my oil because i just drained the oil and it was fine. The hg was replaced 30k miles ago with a oem, and torqed to 80ftlbs i believe. So theres no way i blew any kind of hg, especially running 9psi daily, 12 street, and 14 race on a 50 trim ct-26.

i dk man, u got coolant and oil mixing somewhere, and the oil in ur pcv is a usual sign of a bhg, i had excessive amounts and my hg blew. i dk u might wanan check up on that. maybe the matign sufaces werent properly prepared when u did the headgasket, u can never overlook faulty work.

I dont mean to sound like a dick but where are you getting that information? The pcv routing has no contact what so ever with any kind of coolant. The fact that my engine oil is perfectly normal shows this all the more. Even still how does oil comming through the pcv constitute a bhg? The pcv system routes 2 ways; 1) from block to head, rubber line. 2) The two vavle covers straight to the intake. My coolant never rises temp, never gets low.

Oh yea i also stated in another post, my long block was rebuilt by jasper performance about 30k miles ago. It was a oem hg they put in and torqued to 75-80ftlbs, under NO circumstances should it have gone within 30k miles of boosting no more than 14psi. If it did, i think toyota needs to get into something a little simpler than designing engines such as making mouse pads or floor mats

also note the oil is like milky and white....am i wrong to assume thisis coolant and oil mixing?

[marc]

me and my auto teacher had a talk about this situation, he thinks it is cause of the bhg, or because of exxesive blow by due to worn out piston rings. i dk tho

You can guess all day about what could be wrong. Instead, why don't you run some diagnostic tests like a compression test or a cylinder leak down test? Those 2 test will tell you if your rings are worn causing excessive blowby.

As far as a blown head gasket, there is only one, 100% positive way to determine if its bad or not and that would be with a block test.

You can have white milky stuff in the oil cap and sometimes even the dipstick from condensation from running the motor in sub freezing temperatures and not letting it get up to full operating temperature (driving a solid 20 minutes) before turning it off.

Well another thing i was thinking. My car sits in a parking garage that is about 65 deg. at all times. Maybe me taking it from the -30 degree day we had to the 65 deg in the garage back and forth.

You know what i forgot to mention was. When i drained my pcv, it had probably 8oz of pure water in it. Not coolant but h2O. So i guess that explains why it is milky in there.

I wonder where all that condensation came from though. Like i said, i have a turbo timer so i get proper engine/turbo cool down, and i allow at least a minute or two before i drive the car after cold start (around normal oil pressure). Odd.
