Ok I can't seem to figure this one out. This just started two days ago, I finally decided to take my car on kind of a long ride. About an hour and a half one way. Towards my destination, I went wot a couple times and when I left off the gas to shift, I smelled this awful smell of oil and I don't know what, but it was nauseating (sp). And smoke filled the cabin, then blew out the window.

Now everytime I go WOT it does this. When I got to my destination the valve cover had tons of oil on top. I immediately assumed the oil cap, but that thing is tight as new, so I'm guessing a cracked valve cover. So after I get home last night I take the valve cover off, put a new gasket along with rtv just to be sure, replaced turbo mounting gaskets and dp gasket.

Drove it to work today and still gettting the smoking. Plus there was a huge puddle of oil under my car, the tranny has oil on it, and pretty much everything else. I'm not sure if this is a result of the cracked valve cover, but it did look like the oil was spraying everywhere.

Another concern is the smell of the oil. It smells so damn gross, I seriously can't smell it or I get lightheaded, and no I'm not a p#ssy LOL.

So what would cause the oil to smell like that (burned hair, and acetone?)
And why would smoke be getting in the cabin.

Please help I'm at a loss.

Thanks
 
You need to fix your oil leaks. Oil is leaking onto the exhaust and burning, causing the smoke and smell.
 
I'm absolutely positive the dipstick isn't popping out. I've seen the crack in the valve cover and its a hairline crack, but when I popped my hood, it looks as though that crack was spewing oil all over the underside of the hood, the firewall, and pretty much everything in its spray area.

I would fix the oil leaks if I knew where they were coming from. Which is why last night I replaced the valve cover gasket. To narrow it down.

Another one of my concerns is the smell of the oil. I'm using conventional oil since my engine is a fresh rebuild with only 900 miles, and two oil changes, however this is the first time its smelled like this.

I just got rid of my maft gen 2 cause I couldn't get the tuning right for the life of me. I now have a 2g mas, injen intake, and evo 9 injectors to compensate for the 20% air increase. I'm thinking maybe I was running too rich which may have caused fuel to get into the oil.

Any thoughts?
 
I've just never seen a cracked valve cover spray oil... You said it only smokes under wide open throttle? Since it is an oil issue, there does not need to be a load on the engine, the oil pressure is the same based on engine rpm and temperatures. So pop the hood, clean everything off, start the car and rev the engine or whatever you need to do to duplicate the condition. You should be able to see where the oil is spraying out just by doing that.
 
ok ill try that. Iver read on another post< while searching> that a crack in the valve cover was spraying oil everywhere.

if thats the case, then I need to look into either getting a new valve cover, or jb welding the crack.

I have already cleaned everything, when i went for a test drive this morning, i parked in my garage, and there was no oil, when i came back out from eating lunch, i had some nice little puddles.

I just cant seem to pinpoint the problem. Im not sure if what im seeing is residual from last night or if its new oil. Either way, thanks for your replies.

Still no reply on the way the oil smells?
 
Ok so I think I have it figured out.

I was looking over my engine before work, to see if I could find any possible culprits in my oil burning/leaking problem. Its then that I noticed that the vac line for the pcv valve to the intake mani was dry rotted and hard as a rock, so I replcaed it with a new hose.

Thinking that this fixed my problem, or at least eliminated another potential problem, I drove to work as usual. I had to do a quick take off to avoid some traffic and smoke came pouring out of the engine bay, and into the car frm the firewall.

Scared the sh!t out of me. I took it very easy all the way to work, popped the hood, and this is without a doubt the worst oil leak/spray that I have seen.

I couldn't believe it, oil everywhere, but mainly on the drivers side of the engine bay. I didn't have enough time to really look since I had to clock in. I came back out with a friend and he noticed my dipstick had popped out, and sure enough the spray pattern looked like it was definitely coming from there.

Which leads to my initial sentence of I think I figured it out. Bad pcv valve. I'm gonna replace it, and if that fixes it ill be very happy.
 
Are you sure your dipstick isn't popping out and in?

I thought you said you were positive that wasn't it... anyways how much boost are you running because even with a new pcv valve, your boost will back feed through the pcv valve and into the crankcase popping the dipstick out. My setup only has 1100 miles on everything and I still have a pcv valve, second pull on the dyno at 22 psi shot the dipstick right out. I am now upgrading to a breather set-up and plugging the pcv port on the manifold so no more dipstick blow outs. Glad you found the issue bro.
 
Well I haven't found the problem yet LOL.

I said I was positive, cause I was. I believe before I changed the pcv line, I believe some of tha pressure was escaping that line, which is also wierd because during my blt, it never leaked.

Anyway, now that that line was fixed it blew the dipstick out a good inch or two. Before I think it was just getting past the dipstick, or maybe pushed out a small amount.

Can you explain your process of how you're going to eliminate your problem?

I'm only pushing 15psi right, but would like to be closer to 20.
 
15 psi is still enough to blow it out.

It's called a breather set-up, you need a catch can and a couple lines and fittings. Do it however you want but what you need to do is take out your pcv valve, put in probably a barb fitting, run a line from there to a catch can. Then run a line from the catch can to the breather nipple on the end of the vavle cover. Doing this now leaves the vacuum port on the manifold open so just cap that off. This now provides no possible boost source to your crankcase.
 
Well I did some searching lastnight to see if I could find something to eliminate the pcv valve.

I found some posts,some were decribing what your setup will be nightracer91, and there are some ghetto ways to do. One of those being what I did. Basically I removed the pcv valve, swapped it witht he brake booster fitting on the manifold, capped the pcv valve in its new location (I don't run the brake booster anyway since it leaks underboost) ran a 3ft line from the fitting on the valve cover where the pcv valve was and let the the other end lead out to under the car, did the same thing with the vc breather. Drove home from work last night with no problems. Drove to work today with no problems, no smoke between shift, no smoke in the cabin, and no oily mess under the hood.

Pcv valve is a pos in my opinion. I now have double the vantilation under boost.
