Exclamation JC Sports turbo kit is burning oil and IC is not working (its cold!)

This is a JC Sports kit that I bought off of someone after his crash. He had the same oil prob and him and ISR thought it was the turbo, sent it back, and it wasnt it.

Another thing, the thing is burning oil. The oil is going up from the pan, into the turbo, and going into the IC and thus going into the engine and being burnt up. The car is pulling like its 210hp instead of 250.


This is a T28 turbo with an internal wastegate. We were thinking of an oil return line to fix the oil prob, but is that also the prob for the IC? And how would the return line attach to everything?

I'm going to try to contact JC Sports tomorrow but I want to get some feedback from you guys first.

edited to focus on the oil prob

UUmmmm...you want the IC to be cold, that means its working. If it gets hot, its heat soaked, meaning its not doing a good job of cooling. If you idle your car for a while and don't move, it will heat up. If you're moving, the air moving thru the hood scoop should be cooling off the IC....

Kyles kit worked fine on his car and it pulled pretty hard. If you do a 1st to top of 5th pull and then slowed down, your IC should be pretty hot. But the oil problem, I assure you, its not the turbo, I exchanged that turbo myself.

did you use the JC Sports oil pan?? I remember Kyle used this crazy intriuging thing that screwed into the oil drain. I have seen it work on other cars but just makes me feel weired. Run your oil drain into the side of the oil pan. Minam style. Or call JC sports and order one of there oil pans already taped and pray you get it. Also, how are you running your breather lines???

I agree with TMR... that banjo bolt idea just seems unreliable. Running it into the side of the pan just makes sense and helps gravity do it's job.

If you have oil going into the IC there is definitely a problem.

The oil line that goes down to the oil pan IS an oil return line - do you also have an oil feed line? There should be an oil feed on top of the turbo that comes off the block. The return should come directly out of the bottom and go to the oil pan. If you do not have both of these stop driving NOW!

How many pounds of boost are you running? Why would you expect 250hp instead of 210? 5 lbs of boost is about 215 horses.

What MY is your car? Are you clamping the voltage to the MAP if it is a MY00? If not, it might cut at 3lbs of boost.

I seriously doubt oil is backing up to the turbo, then flowing into the IC and burning up.

Sounds like you might have an oil drain problem...my brother had this on his turbod RS. The oil drain from the turbo was at just enough angle, and small enough line, to cause the oil to not drain well. It would then seep thru seals in the turbo, and leak and burnt out the exhaust (smoke). I bet this is your problem...check the oil drain line, and try to get it more vertical if you can.

And about the IC not working because it's cold, I laughed out loud at that one. I wish all my ICs don't work and stayed ice cold!

Hehe

Good luck!

Yeah Andrew, Intercooler is broken just ship it to Nebraska I can take care of it! hehe

Exactly what ForceFED said. That banjo bolt into the oilpan plug looked really corny to me and I don't even think it will drain properly.

Good luck!

The other possibility for oil in your IC is you crank case vent line! Can't believe no onwe mentioned this. What may be happening is you're experiencing blow-by from the positive pressure from the turbo. What happens is oil vapor passes by the PVC valve and then cools in your intake track. Leading to hot vaper going into the intake, compressor wheel, and then into the IC. When it cools it goes back from vapor to a oil film... This could be a possibility...

I haven't seen the kit so?? If there are 2 lines going into your intake pipe; one is for the idler valve, the other is the crank case breather line(smaller line ~3/8" hose). I'd advise getting the return line fixed first. Look at any 'turbo' book and it will state, 'Oil return line should enter above oil level. Other wise oil will have backpressure or cause foaming of oil.' BTW is it at a constant downward angle?

also check the oil feed. if the banjo fitting is aftermarket the holes the oil travels through is too big. the factory one has a tiny hole .we've seen this on some sand cars and the exhaust will puke oil. see ya steve

Andrew,
After we installed the kit on Kyles car
we never checked it again for the oil usuage.
Kyle had talked to JCSports & they sent another turbo. It was never brought back to us to see why it was using oil.

Hey guys thanks for all the responses. I got through to JC Sports and they said that I may be missing this certain piece. Im not very good with all these parts so I wasnt sure what he was asking me to look for...some oil something. They said if I do not have this piece that it will suck oil up. Soooo....I told them I would email them pics and they said they would call me back when they got them, but no call... So I called them back and didnt reach the person who I talked to before and they told me to call tomorrow for Kevin around 2pm their time.

Anyways, the car is MY00.

Pam, I am aware of that, that Kyle never brought the car back to you guys to fix the problem.

Here are the pictures of the kit that I sent them (this is the view they wanted). If you guys would like other views like from under the car and stuff please tell me because I need all the help I can get....

For those of you with JC Sports kits, could you please post pictures of the same area that I did so we can compare to see if I am missing something?

Thanks again guys,
Andrew

Oh yeah just so you guys know....when I lift up the dipstick after driving, it goes Chhh like its very pressurized

further editing:

im was the phone with Kevin a couple minutes ago and he said that this is my problem (the oil pan). He said that the turbo's return line should be higher up on the side and not right below it. He is going to send me a new oil pan and everything should be just fine I just want to say that Kevin and JCSports has been very helpful and I appreciate everyone's suggestions and pictures and everything I'll let you all know how to goes once I get it up there.

I am glad you got it taken care of. I advise everyone with turbo cars that are first time kit owners to buy Corky Bells book on Turbochargers. Wow!!! This book tells you everything you need to know about turbo kits and how to build your own.

I read last night this very problem. What might of been happening was that if you have too much oil pressure your turbo will leak oil through the seals. If that happens oil gets into you intake/exhaust and gives you your blue smoke. Turbos don't need a high pressure flow to operate properly some need restricters in the turbo oil feed line to reduce the pressure keeping your turbo from leaking.

Your problem might have been like stated, the turbo outlet didn't provide flow and started building up pressure. You might of pushed some oil through your seals and caused it to leak into you intake and exhaust. As stated above tap your oil drain above oil level allowing it to have a constant downward flow instead of an abrupt stop.

This is just a suggestion to what might have happened and caused the blue smoke. Hope the new oil pan concludes this problem for you.

Matt, that is exactly the problem. Its building up pressure becuase the return line isnt above the oil level. That is why I ordered a new oil pan that is already tapped from JC Sports, it should be here Monday (they had it in stock thankfully! )

now the only problem is installing it...

Yup, the only thing that looks bad is your return line (not that it looks broken, its just not the best way to return the oil). The oil pan from JCS with the welded on return line is better, and should probably solve the problem.

This turbo kit had an oil burning problem from the start. Changing the turbo made no difference and we never saw the car again untill we removed the kit, unable to salvage the JC oil pan. We have never had a problem with this banjo drain set up and since TMR`s oil pan (with the drain pipe) is sitting on our shelf, maybe he would exchange it untill JC sends a new one just to end this oil drain debate. I think the crankcase vent set up is the problem.

I tracked through FedEx my oil pan and it was said to be delivered today. I look around the front door and even check the back gate and nothing. I dont know what the hells going on with this, either someone took it from my door step or the guy delivered it to the wrong place. Im hoping that it is the second case and that whoever has it called FedEx or is going to take it back to them or give it to me, or else things might get ugly.
