New turbo, new problem....

[DSMcrazy3]

Alright I finally replaced that blown seal turbo that I had first put on my car. As for the turbo, it's great, much better spool, much more powerful, I LOVE the boost! Only thing is now, after I drive it for about 5-10 minutes, oil has managed to get all over the valve cover, alittle on the head, and on the center section of the turbo. I don't know what it could be really. It isn't the oil feed, it isn't the oil breather, isn't the charge pipe. Anyways, oil is everywhere, but the power is definitely there. Does anyone have some valid ideas??

Thanks alot!

leaky valve cover gasket, and/or a crack in your valve cover?

 

[DSMcrazy3]

The valve cover doesn't have any cracks to the best of my knowledge, I looked all around from where the oil was sitting and didnt' see anything.

If it were from a leaky gasket, it couldn't really get on top of the valve cover though could it..?

Hell if I know I have a 4g63

but if you have a new turbo, and it's not coming from that it kinda narrows down the options. Id also check to make sure your dipstick isnt popping out, on 4g63's that happens a lot and its possible to push oil up through it if you have worn rings, or are somehow introducing boost into your block.

Have you replaced the headgasket lately?? One thing I've read the 420a's are notorious for is a blown headgasket near the #3 cylinder.

I just remembered that the oil return gasket on the turbo that I used on the original turbo, wouldn't come off, and it broke during removal. So I got some gasket material at Autozone, it was the feltish kind with the metal in the middle, and cut one out, could that be the problem, I figured it would seal nicely. I could be wrong though, but I still don't see how oil would get UP on the top of the VC from that..

 

[rowlex]

well, do you see it leaking? id say start the car up and watch..

If it is from there, maybe wind is getting into the area and blowing it onto your valvecover. Generally the oil return line is a non-pressurized line so it shouldnt be able to "squirt" but could drip.

 

[DSMcrazy3]

Yeah that's all that I can think of, but that is why I figured that making my own gasket out of that material would be fine, since it is non pressurized and all. But I don't know I will look some more tomorrow and see what I can find..

our oil dipstick design makes it a lot harder to be blown out than the 4g even under crankcase pressurization. check your breather filter again, then say oh damn....then take your ass down the road for a custom catch can LOWES knows

hahaha man, that was good, you know I was kidding thanks for helping me realize that, and the catch can idea. I'll go make one in a bit, and if that doesn't solve it, i'll be sure to let your ass know! haha

ok so i know this sounds stupid, but if you look around your engine bay look for where there is clean oil, where the leak is, its probly the cleanest part, i know it sounds weird but just think if its coming out its not picking up dirt and the wind then pushes it back all over everything where it than picks up dirt and crap. try it.

 

[DSMcrazy3]

I'm not sure I completely follow, it is pretty hard to find a clean spot though, haha. Although around the breather filter there doesn't really appear to be any oil, I am about to hook a catch can up and take it for a ride and see what happens though.

This might sound dumb, But did you check your oilcap? Mine went bad and oil was everywhere.

 

[DSMcrazy3]

I too have wondered that, if the catch can doesn't solve the problem, i'll inspect the cap. Is there anyway to test it or anything?

 

[1993eclipseGS]

I'm not sure if there is a way to test it. I never seen the oil coming out of the cap, I just seen the aftermath which was the middle well where the plugs/wires go was filled up and as soon as i'd clean it out it'd be back in a day or less. As soon as I changed the oilcap, I never seen a spot of oil there again. I know there is that little rubber gasket on the inside of the oil cap. Mine was there, I guess it just was not letting the cap seal to the cover properly.

 

[DSMcrazy3]

Well I put a catch can for the breather, and I noticed that the part of the feed line assembly that screws into the turbo was alittle bit loose, so I gave it one more whole turn into the turbo, and drove it around and no more oil. I continued to drive, and now there is alittle oil buildup again. I may be able to spin the part in the turbo alittle bit more but I don't think I will be able to get it all the way around again...

I just skimmed a lot of this to be honest with you, but I saw catch can and no mention of a PCV valve. Do you still have the PCV valve installed?

Entia non sunt multiplicanda praeter necessitatem.​

(Latin for "Entities should not be multiplied more than necessary"). That is, the fewer assumptions an explanation of a phenomenon depends on, the better it is.

Pretty much means, the simplest solution is likely the best.

 

[DSMcrazy3]

PCV is indeed still on. What would that due to cause oil to shoot out? If it were bad would the air pressure go through the valve, to the engine and reverse the cycle so to speak.
