freshly built h22 shortblock (cp pistons, je rings,ge sleeves), no oil leaks what so ever, about 140miles on it. -3an feed line -8ish rubber hose return (no clogs, worked fine on old setup etc). 25psi at idle like 50-60psi when crusing around 2500rpms 75psi+ above 3k rpms. Blow by is fine, catch can has not even half a spoon full of oil.

It burned oil pretty bad at first, i figured it go away once the rings got seated. I have an open dp to the side of my car so its veryvisiable. On cold starts it barley if even smokes at all. Once its warmed up it will smoke at idle, sometimes more so when you take off (first gear) sometimes not, but it doesn't smoke noticably while driving.

It has 235 in each cyl, and it still is burning fairly bad (1/4 to 1/2 a quart in like 40 miles). I pulled the IC, a very very slight film in it but none in the pipes. The head is stock (off my old setup that had no oil consumption so valve seals should be fine). The only thing i have left to do is pull the dp and turbo to seeif i can find oil on the dp (exhaust seal) or oil before the turbo.

any ideas guys??

sounds like its possibly your turbo seals. If you have any doubts maybe try putting a header and all back on the car and see if it burns any oil.

 

it'd have to be only the exhaust seal, and it'd have to be pretty bad don't you think? Like, my dp is about 3 feet long, so i think if the exhaust seal was leaking that bad oil might actually drip out. But it is a thought.

I forgot to mention, this happened about a year ago when i put this turbo setup on my stock h22 when i was running 5-30 synthetic BUT the IC filled up with oil (at least 1/4 a quart). I switched to 15-50 synthetic and it never consumed anymore than stock.

And right now i am running 5-30 dino, so it is a possibility, but it should be coming through the compressor side also you'd think

 

Pull it off and check i guess.

 

i'll pull the dp off tomorrow, I noticed a little bit ago that the #4 cyl plug looks to be running rich with slight sign of detination while the others are fine, but it has the exact compression as the other cyl. I think my plug wire is the cause of that though, they are pretty old

 

in the turbine housing itsself there was hardly any carbon, in the dp there was hella slippery carbon, so i know the exhaust seal is bad, but the thing is, i started and ran the car withotu the turbo on and it was puffing oil smoke, so i think like half is the motor and the other half is the turbo.... I'm lost as far as the motor goes

 

After I blew and replaced a turbo I smoked for 2 more weeks on and off. Just crap in the exhaust burning out.

 

i was running it through just the manifold, turbo off, and there was no oil in the charge pipes.

I guess its time to get a leak down tester, to bad i can;t find one anywhere in this town

that's what I was gonna say. Go to summit and pick one up for $70. I guarantee you'll use it more than once.

 

I have to say, this thing runs really hot. Not by the temp gauge but you can just feel it. Plus i drained the oil today and it feels broken down already and its only got like freakin 50 miles on it.

I'm starting to wonder if the oil is just to thin for the tolerences in this motor, or maybe i need to invest in a oil cooler

 

up for ideas untill i get my leak down tester tomorrow

 

up for ideas untill i get my leak down tester tomorrow. I'm goign to go to advanced today and get some thick non synthetic oil additive

 

I started to run hot, mad hot, finally found out it was the t-stat, but in the process I installed an oil cooler also. It helped dramatically.

Just a question, how old is your motor? Valve seals could be shot but they would probably have to be really, really bad to lose that much oil.

Who assembled your block?

I just ordered an oil cooler with my leak down tester. The head is the "jdm 30k" but it was from hmo and i had no issues with buring oil with the old motor (had this head on it). It was only off the old motor fori'd say like 2 weeks then it went onto my built block. So i'm pretty sure its not the valve seals.

I assembled the shortblock and sense this was like my 2-3 build i've done i checked checked and triple checked everything, i know off the top of my head, the #2 compressions are at .021 end gap and i think the #1s are .018

Did you have issues with your oil breaking down, like i figure 5w-30, so the vescosity of the oil should go up as it heats up. Well my oil literally looks and feels like water (consistancy wise), so i'm really starting to think that the oil cooler plus an additive will fix this

 

noticed a little oil around the #4 cyl so i pulled the mani off today and found some nasty **** going on there. everything looks fine except the #4, a **** load of oil in the exhaust port. And with there being deposits on the spark plug its either gotta be the intake valve seals or the rings, but if the compression test comes out fine wouldn't the rings/bore be fine?, i'll grab pics in a couple hours

 

the pics suck i know but its about the best i can do. I did a make shift leak downtest today and came out pissed, frustrated and more confused.

I'll start with a cold compression test i did before anything, from 4-1 i got 242, 240,241,239.

On with the makeshift bs. Pulledthe shrader valve out of the compression tester hose and put 100psi to the #1, i heard a very very slight seapage (normal) so i went to the #4. Hooked it upand air blows out the exhaust. i thought about it spun it around to see if it was on the exhaust stroke but it leaked worse, meaning i was right the first time. Well with no way to bend a valve, i think its just all the deposits and **** that aren't allowing the valve to fully seat.

So I dunno wtf, but the leak down isn't goign to help unless i can seal that valve up some how. And i don't understand how it could be the rings or the bore of the cyl if its got really good compression, but with there being deposits on the spark plug, i can't really see it being the exhaust valve seals, unless oil can creap past the exhaust coming out of the cylinder and into the cyl?

aaaaaaaaahhhhhhhhhhhhhhhhh WTF???????

 

An engine with good compression can still burn oil..... Do you see any oil of the stems of the exhuast valves, if there's oil on the stems, then the valve seals are bad.

 

i guess you could try some seafoam? people said that works?

 

well, theres an oil/carbon mixture all over everything in the exhaust port, including a little bit built up on part of the stem that doesn't go into the guide...but just straight oil, its hard to say.

But say the exhaust valve seals do leak, can oil get into the cylinder from the exhaust port? Wouldn't the exhaust from thecyl just push the oil out of the port, and not allow it to fall into the cyl?

maybe it's the mixture being pushed out of the car through the exhaust ports and it's accumulating? what kind of filter are you using on your turbo?

open compressor. Its def building up in the port but some of it is in the cylinder also, because of the stuff on the spark plug. and the last time i pulled it out, the base around the electrode had oil on it

 

one of the other cyl plugs and the #4 (wet looking)
