So today I put my dejon spring in so i took off my factory intake and i noticed black oil about 2"'s long into goin the intake there in black sticky oil in it and then i look into the turbo and fresh gold oil drops in the inlet on the turbo.....some back round info on this car has a 30% leak down on #3 cylinder and 10% on #1 & 2 and 2% on #4 if this has anything to do wit it. im not sure how turbos run since this is my first turbo'd car...btw car has 16K miles...what do u guys think?!? ill have the dealer look at it next oil change

thanks guys for your imput

 

oil leaks into the airbox/turbo when it passes through the breather for the valve cover. noticed some oil also in the elbow of my factory air box when I installed my dejon spring. hasn't given me any problems thus far and that was 10,000 miles ago.

 

iff you have a bad leak down test do a sea foam to it, so your valve close completely..... if you have a bad leak doen test i say you have a issue with ringlands

 

mine had oil in the turbo inlet as well. Its normal to have some. Get a catch can if you are really ****.

 

Yea thats what im thinkin, the dealer wont fix it till it blows since the car runs good even know max spec is 25%

 

well blo it. u r tuned so i doubt theyll cover it unless you know your ways aroud

 

if it blows it blows...im close wit the owner at the dealer and the guys there....and my buddy tunes it and puts the stock tune on for the dealer just in case

 

Do u think this has somethin to do wit this leak down results or is it normal on turbed cars?

 

It's normal, I'd get a catch can because I'm ****.

 

its normal to have some as I stated above. My ms3 had the same amount in the inlet tube. Just get a catch can.

 

its normal for some oil but not a bad leak down tests.. so sea foam your car since d.i injection cars like to gum up and cause issues. and do a compression test and then do another leak down test to see if results changed

 

oh i thought the OP said, the history of the engine was it had a leak down but was fixed. Get that **** looked at first.

 

lol bro........

 

I dont like reading sometimes; specially if the grammar is all fucked up.

 

yeah i dont really have bad grammer but i am usually on the phone on the web typing with it lol so it confuses the hell out of people wut come out when i was done with my sentences.

 

k thanks man for the help ill let u know the outcome...whats the best way to do a sea foam?

 

put 1/4 in your oil, 1/2 through your brake booster hose, or another vacuum line off the intake, 1/4 in gas tank, when doing the intake mani part, suck 1/2 up turn the car off for 3-5 mins and run it then drive it. thisis the best way ive done it

 

lol @ seafoaming new cars...

It's almost like a fad on here

 

really^^^^^^ u know anything of di injection. if not then ill let you kinow why we do. DI injection gums up bad, top of pistons, ect. Ecspecialy when tuned for more boost and fuel, So when this happens we lose comporession and so forth so this is why we sea foam. Nothing is wrong with sea foaming. i sea foam my casr every oil change to make sure i get the 100% best out of my car. .........

 

K thx guys ill try this out an do leak down test before an after

 

k bro keep us updated

 

So does every car, what's your point?

Your next thread will be "Did seafoaming just **** up all my sensors and cat?"

That stuff was the **** back in the carburetor days, but with modern sensors you're going to **** **** up.

If you got that much carbon buildup, it's time to take your tuner out back and put them out of their misery haha. It's not being tuned that does this, it's the tuners inability to get the right air/fuel ratio that causes the excess buildup. ^^^^^^^^^^^^^^^^ u know anything of gasoline!!!11

And the carbon buildup is probably from blowby dipshit, not because engineers decided on using direct injection, get a catch can.

 

Also is a oil change required? An when u say 1/4 & 1/2 r u talkin about the bottle?

 

yes oil change is required. And numb nuts up top. U have no clue who u are talking to with that idiot attitude. By far d.i are not a mpi system or a port fueler. So since u have no clue wut your talking about please leave this thread. and tuning , i had my old lnf engine tore aprt and guess wut, no carbon build up, but if i were to not sea foam my car it would have build up becase of the way the injectors spray lame. trust me on this ive been using sea foam for a long long time, and not one have i fu**ed anything up , the worst i did was spill seafoam on my shirt, i mean really bro ..

 

also i forgot to post this!! I hope you understand i am the tuner of many many many many cars out there prob in the 100s if not 200s, in the toyota, honda, mitsubishi ford, dodge and more, (including gm) so with you saying do i know anything about gasoline i ummmmmm i end it here so u can understand who you are talking to im not a idiot down the road..
