STS Turbo problem

[aquickfive0]

i have a 2002 trans am with a sts turbo

i am having a oilish water come out the exhaust

the oil itself in engine is clean, the water in radiator is full, it has rained here alot in florida in the past few weeks.

[aquickfive0]

took silicone hose off throttle body and was clean no oil

[cailey37]

The oil isn't getting out of the turbo fast enough. You can go to the oil pump on the back and right beside it there's a pressure switch. It's set to like 3psi from STS but if you take an allen wrench and turn it all the way down and then give it a half a turn back you'll turn it into a 5 psi switch. It should get the oil out quicker. Also, make sure you have the return hose routed OVER the rear axles.

[aquickfive0]

this is a new problem, it seems it would of done that the whole time, this problem just started hapening

[aquickfive0]

seems oil might sumhow be come after leaving turbo, i still have no oil in front of car when i pull throttle bos hose off so seems its lingering around rear from turbo to exhaust tip

How many miles do you have on the turbo ? You may be pushing oil past the seals ?

What size turbo do you have. You could have them rebuild it to a T67 for only 450.00

[aquickfive0]

i can get a regular t3/t4 redbuild kit for like 100, cant u get another turbo off ebay or sumthing?

[cailey37]

I have no idea what you guys are talking about. There are no "magic seals" inside the turbo. A turbo has a loose fitting shaft that is supported by two bearings.....The problem with the STS systems is that sometimes the oil doesn't get evacuated fast enough and it overflows the bearings. I told you to take a look at the switch beside the pump itself. I almost bet there is nothing wrong with your turbo. If you just take an allen wrench and carefully turn the screw all the way down and then back it off by half a turn I bet this would take care of your problem. Is the oil line run over the axles?? If it's not that is your problem. Before you go and waste your money on a rebuild kit or another turbo try this out.....

Yea, I've seen the ebay turbos, I don't know if their good or not, but i've heard they use garrett parts.

To me it dosen't sound like a bad turbo it sounds like something else. Have you checked over everything, is it returning oil? are the relays working? a bad relay can cause oil out the turbo, its happened to me when I got water on it. Is the buzzer going off? And yes the turbo does not have seals.

[aquickfive0]

the oil is returning, about the oil pressure back t the engine, how will it affect it now, kit has been on for months and now its just having this problem, shouldnt that of been a problem since it was just installed or can it change?

[cailey37]

do you just notice it after you've run the car???? or is it coming out when you drive??? It it's happening after you run it and then it sits for a little while then you could have a bad check valve on the oil line to the turbo......it's allowing the oil to seep inside the turbo.....

[aquickfive0]

i had a bad check valve before and then it loads up oil in the turbo and i can tell, also if feeds the oil back into the engine but the lines goin back to motor is clean, seems to be leaking after leaves turbo

[JD_Z28]

Is the buzzer going off? Is the pump comming on? You can also test your power to your check valve.

[aquickfive0]

the pump is comming on and oil is returning to the engine

[aquickfive0]

explain what i am turning where it exactly located adn what it looks like il try that

[aquickfive0]

i dont see the allen bolts

[JD_Z28]

i dont see the allen bolts

How much boost r you running? test the line to the switch and make sure your getting power to it. The buzzers not comming on right.

[aquickfive0]

the oil is running properly and the buzzer is not sounding, where r those alen screws? i cant find them

Maybe you sucked in water and its just mixing with old condensation from before. I remember you had a similar problem before, right. How bad is it and how long has it been doing it for. If its been doing it for awhile theres a problem.

[JD_Z28]

Are you sure the head gasket isn't blown? Mine did the same thing when I broke a piston and blew the head gasket. There isn't oil in the coolant.

[aquickfive0]

i did suck up wate r its been raing alot here and ive been outa town and my brother been driving, it only been doin it dor a day i just noticed

[aquickfive0]

coolent is full oil is clean not milky in motor

[aquickfive0]

old problem was fixed, check valve was stuck open

[aquickfive0]

this problem has differtn symptons but you all helped alot last time

[JD_Z28]

I say drive it around a bit and see how bad it is. It might just need to purge itself from the water you sucked in. hopefully you didn't suck in too much. If thats not the case then I would say the check valve is bad (pretty common)

[JD_Z28]

I posted this on ls1tech hopefully we get some responses.

[Boostaholic]

You should really post this in the ls1tech forced inducation area for best results

[cailey37]

The allen bolt you're looking for is right next to the oil pump for the turbo....in fact it's on the same assembly.....as you look at it, it will be on your right....there will be a rubber grommet the size of a pencil eraser on top...you'll have to remove that and the allen bolt is located there.....again...be very careful with it......in fact....if you just give it about 3 full turns you'll be fine.....give me your email address and I'll give you a article about oil problems on STS kits...it's about 8 pages long but a good read.....

nothing here thats aquickfive0@aol.com with a zero at end

i sent it again....

[aquickfive0]

got it, hmm says sumting about dirty air filtre, mines really really dirty and i didnt put shield on yet

[aquickfive0]

i must be stuipid casue i cant find that screw to adjust

[aquickfive0]

i found screw and turned clockwise til tight it turned about 7-8 turns and the backed off counterclockwise 1 1/2 turns

[aquickfive0]

i put the plate over air filter but i need to change filter its nasty

[koolaid_kid]

You don't change a K&N filter, you wash it from the inside out with soap and water. Then you re-oil it and put it back on.

[aquickfive0]

i think this 1 is way to nasty to clean and sum of the ribs are messed up, does any1 know what model filter this is anyways

[cailey37]

Pull the oil cap off with the oil return line still attached....you'll have to take it off first....but once you have it off and the oil line hooked back up start the car and see how much oil is returning.....you should see a good bit....Also, I can't stress this enough....but make sure the return line is run OVER the axles.....this prevents oil from returning to the oil.....if you checked the check valve and it's not hung open then it's a return problem........how much oil are we talking here?????

[aquickfive0]

i rode car today, it cleaned up pretty good, just a slight oil in exhaust now, probably left overs, it was a oily film all around tail pipe and when rev up, st 1st it was dripping milky like it has water mixed with it. but looks pretty good today il recheck tomaorow clean pipe and ride sum more

[koolaid_kid]

You can contact K&N, they will ask you for a number (it is on the rubber neck, they can tell you where to find it). It will cost you in the neighborhood of $75-100, most likely.
I have run K&Ns for over 30 years (on motorcycles) and I have never seen one that can't be cleaned with consistent applications of soap and water. Just my two cents worth.
If the ribs are messed up, look for places that have broken through. If it has, replace it.

[cailey37]

Also, I'd look at tapping the cylinder head with an AN fitting and putting the oil return line on that.....Ive never liked that oil return line sitting right on top of the rockers.......when you get the bug to turn the boost up....and you will......I've found that it likes to come out the bottom of the cap........
