to much oil to PTE?

[Burnett03]

I have a PTE 50trim turbo that ive had for about a year. i noticed tonight after boosting it a slight smell of burning oil. It was coming from around the turbine/exhaust housing where it meets with the center catridge. I looked underneath and noticed a sort of black tar/burnt oil around it. Im thinking that i am running to much oil pressure to it. I have a 6bolt with no balance shafts and i feed off the filter housing. I see pressures of 100psi at times with it. Should i run a restrictor? Will the leak stop? Can i use the -4an resrictor for the GT garretts

I have no bshafts, and feed from the oil filter housings with no restrictions and no problems so far. Ive been doing so for a year and about 10k. The tar'd oil may be from the oil return line possibly. I suppose it is alot of oil pressure for a turbo, but i noticed those with greater success of the PTE's are feeding from the oil filter housing and or have bshafts removed.

I wouldn't put a restrictor in it as long as you're using one of the feed kits from the housing. Typically there are many more failures from a lack of oil than from too much oil on mitsu's. Check to make sure you don't have shaft play and make sure your oil drain is clear.

I keep hearing you guys talk about checkin the drain for blockage. WIll oil blockage cause the oil to blow out of the seals if the drain is blocked? I use a stock 1g drain that it hacked with heater hose in the middle. I recently ordred a -10an line which should be bigger and not have bottlenecks like the 1g/ghetto setup i have now. If i get this on will it possible stop the oil leakage from the exhaust side? THanks guys.

DUDE i know what your problem is as i too have a 6bolt with no balance shafts and i just bought a new T04E 60trim a few weeks ago from bullseye. Well i too see Very high oil pressures and i have my oil feed taken from the filter housing... And within 2 days i was pushing a 1/2 quart of oil through both the Turbine and Compressor seals. my car started smoking really bad so thought i thought the turbo was blown and sent it back... Well the Garret technician told me my turbo was very healthly and pulled the correct amount of vacuum from the seals. He said that my turbo is not to see anything over 55psi of oil pressure... So i asked him if he could install a restrictor and so he did and cleaned up my turbo in the process.. I should recieve my turbo This upcoming monday or tuesday.. And guaranteed me it would not smoke when i got it back. He told me this problem was caused by either 2 things... Either A. Too much Oil pressure or B. a restriction in the Oil return line which in my case was A. too much pressure becuase i have the -10AN stainless return line which is a 1/2" diameter... He told me that Oil only turbos spool up and run alot better with lower oil pressures in between 30-50psi. So yeah i Highly recommend a Restrictor unless you want a neverending smokescreen trailing from your car...The funny thing is this is my 4th turbo install and ive never used a restricter ever. But then again i also had balance shafts and watercooled turbos too hehe good luck.

Wow thanks for the reply.. So oil was coming out of your exhaust housing too? A restrictor solved it? WHere did you get this restrictor? please reply asap so i can get one, thanks again. I'm running -4an from the filter housing, is that what you have?

 

[Turbo Monk3y]

Well i had oil coming out of the Compressor side going into my intercooler and oil oozing out of the Turbine side being burned and causing mass smoke clouds... Well i havent recieved my turbo back as this just happened to me last week and the technicians at bullseye have my turbo now and installed a restrictor on it and it should be back at my house either tomorrow or tuesday the latest... I noticed when i put my 6bolt together and removed the balance shafts that my oil pressure was really high compared to my old stock 7 bolt motors oil pressure. My Oil feed line is -4AN just like yours and my Oil return is -10AN SS. heres some pics of the turbo just taken out of the car.

ANy idea where i can get the restrictor? I e-mailed bullseye with no responsive. I recently ordered a -10an line from them for the drain but they forget the 45 an fitting so i cant use it yet, and they havn't yet responded. My oil pressure is also high with out my BS shafts. The car only seems to smoke when the rpms get high and the car is boosted so i think less pressure would be ok. Now if i can find the orifice..

I personally have no idea where to buy an oil restrictor as i said before this is my 5th turbo install and ive never used one. But apparently on the turbos that are Oil only they require them which i learned the hardway. Unless you get your oil source from the head. But ive always taken mine from the oil filter housing.

why don't you try a bigger oil line like a -6an instead of a -4an...with the bigger line you'll have less pressure more volume...just my 2 cents

 

[Tallen]

A .060 to .080 hole should suffice. Grab an autometer oil restrictor and drill her out.

[qwkdsm2]

just get one of these fuel restrictors from auto meter and drill the hole bigger

[Burnett03]

thanks for the reply guys.. does anyone else have to use a restrictor? How much will a .08 orfice reduce pressure?

The seller of my used AGP Turbo had this setup on his oil feed (Earls swivel + .078" NOS "flare" pill) which I didn't use:

I also don't run BS and feed off the oil filter but have an open PCV valve and large bore Crankcase vent which seems to help alleviate crankcase pressure which can also cause oil blowby (excess pressure in crankcase can inhibit oil returning to the pan).

 

[Burnett03]

Makes sense this did happen after i installed and ditched my PCV valve.. Maybe im still not getting enough crank case pressure

 

[Burnett03]

anyone use, or know where to get a -3an oil kit?

I have my rs 49 fed off the oil filter housing.I also have had two recent incidences of big time oil out the exhaust and leaks out of various gaskets.In both instances it was blockages in my lines.I have pcv valve deleted with straight fitting and feed that to a rre breather catch can and then back to the engine.I added an extra fram g2 pos to the line from the head thinking it would keep the catch can even cleaner,big mistake.!!! It clogged up pretty quick and caused the first heart attack I blew my engine experience when I killed every mosquito in a ten mile radius.
But serious the car smoked and leaked like crazy.Fixed that too out the exta g2 and things were good and then a week ago same thing big smoke cloud and once again it was a blocked line from the pcv fitting to the breather can.I am not 100% sure what it was in there but suspect its that garbage restore can I put in the engine trying to get rid of phantom knock.I should have nixed the idea of that restore when I saw it,it is super thick and dont pour at all so can't see how it can ever get out of my engine.

Anyway I am a bit worried about too much oil pressure also and if I can cut it down and get a bit faster spool and stuff that would be a good thing too.
So lets keep this thread going.I think the turbo suppliers need to get on this and sell restrictors with these turbos.

My AGP L2 has a built in restrictor on the oil inlet elbow.

Also you have to remember that too much oil pressure won't kill a turbo but too little oil pressure will. As our cars all have varying oil pressure due to oil pump condition, internal modifications and oil blowby, there is no one-size-fit all solution.

I like that little gadget that I linked above that not only tells you what your oil pressure to turbo is, but also allows you to adjust it. IMO this is much safer than throwing random sized oil restrictors as you don't know what the end result will be.

I think will order on of those regulators they seem cheap enough.How high would I set the pressure on my rs 49 50 trim.Does that device fit on my current line going to the oil filter think its 6 an or do I have to buy adapters to fit that regulator to my line in between and do I just set the pressure at idle is that sufficient? It looks like a nice toy.Does it have instructions on what pressures to use? I am not sure I get oil leaking/burning much with my current turbo and oil pressure but might if take out the balance shafts which plan to do shortly.

 

[qwkdsm2]

im looking into buying this turbo oil filter....it has a built in restrictor...its from forced performance

[anconover]

Im not sure oil restrictor and cheap enough should go into the same sentence. Be careful restricting your oil pressure. I had a LIGHT residue in my compressor inlet but not enough to make me want to reduce the amount of oil pressure my turbo is seeing feeding from filter housing with bshafts removed. Ive run my PTE like that for 10k/1 whole season without a single problem.

 

[DSMRevolution]

Good thread. That makes me curious about my 14b. Since I pulled my balance shafts I have much higher oil pressure (I do not have a aftermarket gauge, just the OEM gauge) until the car warms to operating temperature. When the car is cold (under 170 degrees roughly) I get a slight studder under acceleration and smell a faint oil burning. I don't believe I am having problems with my valve seals and I know my rings are fine (less then 7 percent leak down each cylinder) unless the seals on my turbo are in fact going out. I guess I get to pull it apart one day to check it out. Does anybody know anything else about vacuum testing turbos to check the seals?

remember that restrictor/filter is for ball bearing turbos. it wont provide enough pressure for a regular one

You wont get a faster spool up, but i do agree these turbo suppliers need a restriction for us guys with high pressure
