car is pushing oil everywhere

[stuckinkaos]

This issue just started yesterday coming home in the morning. I dont run the car hard and im only running 18lbs of boost.

I my whole bottom half of my engine is covered in oil. I also have oil in my turbo and intercooler puping. I can see oil around the bov flange. The car leaves a trail of smoke as I drive it. Now, about the same time, my check engine light popped on and off a few times and my oil pressure gauge stopped working. The wire to oil pressure sending came off.

Things that I did yesterday was, I pulled the valve cover and retorque the head. I will replace the pcv valve today. I used my air compressor and added air to the end, and I got some air past the valve. This would explain the oil in my piping.

What would cause my car to squeeze oil out of the headgasket? No oil in coolant and coolant in the oil.

You can be leaking from the valve cover AND possibly the turbo feed line. Clean it all off with brake clean and let it idle and have someone give it some gas while you watch the front of the motor to see where the leak is coming from.

Are you sure the head gasket is leaking oil, not a cas ring, or the vc, if you had oil leak at hg i would assume youve got some problems in that area, it could be coolant from the thermostat housing, leaking on to the hg near the head and the block. Also grab some dye and let it run through the system.

Is the smoke coming out of your exhaust or just burning up in the engine bay? +1 for brake clean and letting it run

Retorquing the HG will not solve an issue, if oil worked its way between the the head and gasket, head and block. The gasket is contaminated and will not seal properly.

Were the head studs/bolts loose?

With oil in the turbo and IC piping, and at the BOV flange, would point to bad turbo seals.

Now when you put air in the cylinder, how much? what pressure?

You say air past the valves, Intake? Exhaust?

Did you pull the VC and confirm that the valves were closed on the cylinder you tested?

Now when you say the whole bottom half of your engine is covered in oil, what half? Intake side? exhaust side? Timing belt side? or trans side?

When you lifted the hood. Was the dipstick popped out?

So i cleaned the front of the engine. Its leaking right behing the center of the manifold and running down the block. I noticed my bolts on the bottom of the manifold were loose. Does the bolts run into oil galleries? Im goin to die and tap the bolt holes tonight for bigger ones. Also noticed a small oil leak near the passenger side rear valve cover by the sensor that is attached to the cam gear.

Also. My crankcase has a lot of pressure inside. Lots of white smoke from the engine oil fill hole. Ibalso still have oil in the turbo. I know its now the turbo because oil is just sitting in the intake tube goin to the turbo from the maf.

What is the vc and case ring? I was also saying air was getting pass the pcv valve when I used my compressor to apply pressure to it. Dipstick is also not popped out.

This car had mls gaskets and arp head studs less than 7,000 miles ago. Head was decked, basically a new head.

Yes, one of the lower manifold studs goes into the oil galley. I believe it is the lower one on the #4 cylinder exhaust port. Some thread sealer like Permatex #2 will usually work to stop the flow of oil. As for your pcv valve leaking, you need to get one of these and put it between the intake manifold and your oem valve. It's a foolproof check valve that's rated to 150psi. I guarantee it will not let boost leak back into the crankcase.

Also, on a side note. If you have oil in the intake pipe that is usually a sign that it may be time for a turbo rebuild.

It could also be blowby if he has his pcv system routed incorrectly.

Also, +1 for the kynar valves. I have a whole bag of them in my car.

The only exhaust stud is the bottom center. Just pull that stud and a small dab of RTV will seal that leak.

The one by the sensor can be one of 2 things, the O ring on the CAS sensor is leaking, or The VC gasket is leaking where the cam cap meets the head casting, a spot of RTV will seal that leak.

No need to drill and tap for larger studs.

Good the head was decked, but was it milled for a MLS gasket? Was the block decked?

How is your PCV system routed?

Yes, one of the lower manifold studs goes into the oil galley. I believe it is the lower one on the #4 cylinder exhaust port. Some thread sealer like Permatex #2 will usually work to stop the flow of oil.

You are close, the oil feed from block to head is over that way, the oil runs up that last head stud.

It could also be blowby if he has his pcv system routed incorrectly.

Fixed

Thanks its hump day.

 

[stuckinkaos]

Figured out my problem. I did a compression check. #1 125psi, #2 60psi, #3 130psi, #4 135psi.

Dont know what caused this, its time for a rebuild or ill just sell the car. Dont know what ill do.

 

[Ghost_92TSi]

Valve got damage and messed up the valve seals? Do a leak down test and see where it is leaking on #2.

 

[stuckinkaos]

Not worried about a leak down test. Still habe to pull the head off to rering the pistons. I dont think its the head.

Ill get another headgasket, new rings and maybe some new rod bearings while im at it. I kinda like this little car a lot.

 

[delta448]

If you don't have huge power goals, a non-MLS headgasket is much more likely to seal. Since you already have ARP head studs, that's the route I'd take.

Let us know when you find the reason for the low compression on that cylinder.

 

[stuckinkaos]

My power levels wont go past 350hp. It has a Mitsubishi mls gasket now. Ill just got with a good felpro gasket.

$100 for new rob bearings, timing belt, headgasket, new piston ring set. Ill fix it since it has head studs in the car already.
