i have a 99 civic dx hatch with a dsm t25. My oil feed line is an -4an. I am getting to much oil to my turbo and it's burning it like crazy can anyone tell me what i should do. I read something about a valve just befor the oil inlet but it wasn't very detailed. Any kind of help would be great.
Thanks

 

You should be using a -3an feed line. That helps to restrict the flow.

 

What are you using for a crankcase vent/breather? (stock or aftermarket)

im using the stock

 

last time i got cheap, i just used a homedepot water line for the day, its steel braided like 6an or some ****, it had no leaks or problems. maybe your seals are bad? you can also use a restrictor but i dont know where you can find them. just make things easy and use a 3an.

 

I would check your crankcase pressure, if it is high you may want to look into an addition to your oil separator system. (ENDYN, SSR, Greddy all make oil separator cans) and use ENDYN's installation instructions.
High crankcase pressures restrict oil return lines and cause oil build up in the turbo center housing....thus passing oil through the seals.
If you are still passing oil from the turbo seals, I would also suggest changing to 3AN feed line, it can't hurt. Good luck


What are you using for the return line?

 

i'm using a 1/2 inch radiator hose

 

im using a -4 an for the oil feed on my t-25 and no problems here.
