you should get an oil restrictor. is your oil line a AN-4 , that might allow too much oil volume. a restrictor could solve your issues. 98ctr

yea i was thinking about that. do u know if any kind of local places would carry them or r they special orders.? thanks for the info.

Re:bad return line lots of smoke!!!
 

do NOT use a valve from home depot (brass fitting section).

i tried one and blew it out the next day.

get one from stealthmode for $12 shipped, i am

Re:bad return line lots of smoke!!!
 

get one of the regular ball valves, not the ones from the brass section

Re:bad return line lots of smoke!!!
 

I took a stainless AN union welded the inside of it and then drill a .050 hole straight through the middle of it. 98ctr

Re:bad return line lots of smoke!!!
 

so would my local earls oil fittings store carry one?? and if u go to home depot do they look like the ones on steathmodes link? but thanks for all the info.

is this a oil restrictor or no http://members.ozemail.com.au/~earls/plumbing.htm

Re:bad return line lots of smoke!!!
 

hmm what setups need oil restrictors?

Re:bad return line lots of smoke!!!
 

from what I know, anything smaller then a full T4 should have an oil restrictor. But thats just what I heard and don't know if its 100% accurate. I do know that xs.engeniring tells everyone to use a oil restrictor if you are going to use a AN-4 oil line. 98ctr

Re:bad return line lots of smoke!!!
 

hmm im using one of those and havnet had a problem... il keep an eye on it thou

Re:bad return line lots of smoke!!!
 

well, i looked for a ball fitting restrictor and could not find one that didnt have a rubber seal or plastic parts.

i even looked in the aircompressor fittings as well and they still had plastic in theirs.

as for which valve is not good from home depot. i will take a picture of the one i used and show you why it did not work for MY setup.

remember, i dont have a honda or other import. i have a GM 3400 3.4L v6 that ive turbo'd and the oil pressure can and does exceed 60psi.

what ive done to help control it for now is this...

took a 1/4 sold aluminum rod and drilled a 7/64" hole thru 3" section and then cut my feed line and inserted the rod into the hose and then clamped the cut ends back on.

it did lower the psi a lot, but still not enough to stop the oil seal leak on the turbo.

so what i did was take another clamp and then tightened it on hose itself, nothing in the hose to clamp onto so it slowly closes the oil feed tube.

by doing this, it lowers the oil pressure before my restrictor and allows me to control the amount of flow coming out of the tip.

this is only a temporary solution

again, i would recomend stealmodes restrctor valve.

Re:bad return line lots of smoke!!!
 

In my case, my rhb5 turbo has a banjo bolt that has a tiny hole in it... that's my restrictor.

Re:bad return line lots of smoke!!!
 

mine looks just like that but its brass


if you take off the "top" part with the screw in piece that actually tightens the rod on the inside, does that thing have a rubber O ring in it? if so, mine blew right past that o ring and dumped 4 qts of oil all over the front of my engine.

Re:bad return line lots of smoke!!!
 

7/64 its still .109", if the turbo is old and smokes alot, take it down to .050" hole, that will help out alot.

Re:bad return line lots of smoke!!!
 

Yah mine is brass, i havent taken it apart so i cant say there. Like you said earlier your car prolly has a lot more pressure than my honda and i have a fitting on the block that has a little hole so i guess that helps too. I think i bought it before stealthmode was selling his resistors.

Re:bad return line lots of smoke!!!
 

i did have a smaller bit than 7/64'ths, but it broke the second i applied pressure on my first piece i tried to do. it was steel and as soon as it broke that bit and the next bit, i went searching from some aluminum rod.

by the time i found the rod and got the drill bits rounded up again, the smallest i had was the 7/64ths.

i will probable go get another drill bit that will hold up a little better this time around.

make sure you copy and paste the WHOLE address, including everything after the -'s

Re:bad return line lots of smoke!!!
 

My turbo was re-built, it smoked from the start. I figure driving it with too much oil going to it blew the seals out. Made my oil return nice and straight and put a restrictor in and it still smoked. Ended up having to rebuild the turbo, good luck.

Re:bad return line lots of smoke!!!
 

why can't you do this???

Re:bad return line lots of smoke!!!
 

thanks alot guys but i fixed it by buying a smaller oil line smoked for a bit than cleared up. :).

Re:bad return line lots of smoke!!!
 

having the oil drain pointing down helps alot too...
