to much oil to PTE?

[92awddsm]

Well, I just gort my scm 5252(was supposed to be a 6152) from slowboy today and the instuctions state clearly Do not use a restrictor in the oil feed line I called Mike to make sure and was told that pte 360* bearing cartiges need all the oil they can get.

Do you think they realize that some of us guys with no balance shafts pull 100psi pressure?

I also have no bs and when I told them that I had over 100psi oil pressure, they said thats fine. Seems a little strange to me but Im going to run it without a restrictor and see what happens. If it takes a sh1t, Ill just send it back and say "I told you so". Maybe they would send me the right turbo next time.

PM me if you want my restrictor setup.

SBR sells a restrictor at the bottom of their turbo accessories page or one of those pages..

The only one I saw on SBRs site was for the GT-Series turbos which require much LOWER oil pressure. Use that on your std bearing turbo and you'd f-- it up pretty quickly

Well i just got my T04E back from bullseye as my turbo was smoking and i thought it was the seals but they told me it pulled the correct amount of vaccum and was perfectly good. So my new turbo setup starts with a -4AN feed line with a 1/8" restrictor (hole is very small hole), Then i have a modified 5/8" return line This thing is HUGE almost a full inch from turbo to oil pan. I have also replaced my PCV valve with a catch can so i can relieve crank case pressure. Now the smoking at idle stopped. But i still have non stop smoking during shifts and WOT.... This is really pissing me off as ive already spent another 80 bux on shipping to and from the company. I too have my balance shafts removed but i really really hate blue smoke puffs coming from oil blowby with all the stuff i just listed... And no its not my motor as my 6bolt is brand new and i just checked the compression yesterday and got 161 160 160 162. Any ideas? im stuck and i really dont know what to do...

Do you have new valve seals.?
Also I had two incidents of huge smoking but it was at idle too with my rs49.
It was blockages both times in my lines from my pcv to catch can back to motor.One time left a g2 fram in the line from catch can to engine and one time had blockage from the pcv outlet which was a straight fitting to my rre catch can.Both times it was massive smoking and thought the engine was blown or the turbo.But supposedly turbos at least my garrette don't blow very easily from that.I guess its possible its excessive oil pressure that guy that listed that cute little regulator gauge seems like a good thing.Need some honest answers mabye from the turbo manufacturers on what is minimum oil pressure that should be run thru them.

I had the same problem with my Garret.It didn't have any miles on it .It just started to smoke.Smelt like oil burning on something hot,not in the combustion.I removed the oil line and went down to G&J aircraft to get a filter/restrictor put on.He instead hooked it up with a 90 deg -4an fitting with a 1/8 npt pipe thread and a 2mm restrictor inside.I too have no balanceshafts.This helped out alot.I also had oil seeping from the housings.After installing the restrictor, the car doesn't smoke as much.Still need to get the rest of the exhaust hot to burn off the leftover oil.

Quick FYI.. Turbo oil seals are not truely "seals".

Taken from Forced Performance's FAQ

The seals within the turbo are not meant to hold back a bearing housing that has become full of oil. They are designed to sling the oil mist and spray within the bearing housing away from the point where the shaft comes out each end. If the bearing housing becomes full of oil it will ooze out past even brand new seal rings.

The oil should freely drain out of the bearing housing as quickly as the engine supplies it. This is why the drain tube is so much larger than the supply tube. Gravity is the only force moving the oil out of the turbocharger. Any slight restriction in the oil drain tube, even a small silicone dingle berry, can slightly impede the draining of the oil and cause oil to back up into the bearing housing

Making sure the return line is the maximum diameter (and not-kinked) along with reducing crankcase pressure as much as possible is the answer. I've even heard of folks using a vaccume pump or routing their PCV to their exahust to further mitigate crank pressure.

Even with balance shafts removed, I would never run a restrictor(on a non ball-bearing turbo). I've had one of our Garrett oil only centers on my 1G for almost 2 years. Built motor, no balance shaft, oil off the filter housing, and have never had a problem. The only time I've seen oil out the turbine and compressor of a customer's turbo is when the bearing has enough wear to let it by. Almost every turbo that comes back has been starved of oil or has has foreign material in it when the customer thought it was just too much oil pressure.

Make sure you have a clean, unrestricted oil feed to the turbo and a FREE FLOWING drain, with no kinks or tight bends.

Yup i have a 2mm restricter as well and it seemed to have helped alot. But like you said i too need to still burn off and ass load of oil that went into my downpipe/catback. I was curious as to what setup for your pcv valve are you using? I have my pcv valve rerouted to a very small catch can and i have the intake hole blocked where the pcv valve was originally routed too.. Is this right?

Try and run a -3 feed line only, any bigger will cause to much oil pressure and blow right past the seals. Jim

 

[Burnett03]

thanks jim, i'm putting a -3an line on tomorrow.. I hear you guys sell -3an line for PTE's? Seems to be the solution to oil leaking out, so why does slowboyracing, and many others say that PTEs are fine with -4an and high pressure?

I dont know why they use that size line but we use -3 on all the turbo kits we sell. its more then enough.

Well i scrapped the whole -4 an from the oil filter housing and i now have a -3an coming from the stock 6bolt head location to the turbo... The car does not smoke at all at idle or sitting still. It only gives out puffs of blue smoke while normal driving sometimes while shifting and WOt runs... The head location has way less pressure than the oil filter housing and my turbo was checked over by garret techs and i was told it pulled the correct amount of vaccuum. My motor is fresh with 162psi across all 4 so its not the motor.. I know its the turbo because when i do a boost leak test and cap off the compressor housing and fill the intercooling system with air the only leak i get is inside of the turbo.. i can hear hissing and bubbling, and i always find oil inside of the compressor housing not alot but films of oil... the only thing i can think of is maybe Crankcase pressure... Any ideas ??? i mean this is the only problem my car is having other than that the car performs great.

The only thing i would be worried about is with standard bearing center section i would run from the oil filter housing because it needs more oil as with a dual ball bearing it needs less there for you run the oil feed line from the head. Jim

update: -3an line is a no-go. Still burning oil off the turbo. It only does this when its taken WOT and the oil pressure exceeds 110psi. Im stumped on this one. I'm looking eveywhere for a 2mm like you guys say but cant find one. Give a brother some help!

2mm what.

Are you sure your not running to rich and you see the extra gas coming out the tail pipe

sorry, 2mm restrictor, which the other guys mentioned. Its not smoke from the tailpipe, its smoke from around my exhaust housing. I put the PCV system back to stock-like tonight and i think it made it a bit better.. I havn't got a chance to really beat on it yet and see.

 

[miragetbo1997cc]

The one I got is a -4an 90 deg steel fitting .The 2mm restrictor is in the elbow.Anywhere that sells aircraft stuff would have them.The place I got mine is near Ontario Airport..The car no longer smokes .Not even a WOT.


I have no kinks,rebuilt head,new turbo ,oil feed from the oil housing,no balanceshafts,and the car did not smoke till I installed the T4.Can anyone explain why this works and nothing else would?I even think that the high pressure is what blew out my B16G

Here's a write-up I did about the oil restrictors..... Maybe it can help you. If you can figure out how 2mm tranlates into nitrous jet sizes, then you can make something like this....

ya i saw your writeup, nice BTW. I've got a nitrous jet coming in the mail with the same .78 as you use. DId it help you? Why did you do it, what does it bring the pressure to? Thanks

I did it because of previous oiling problems with other turbos. I didnt want to over-oil this one and mess it up. I'mm still waiting for the snow to melt here. The car's in storage and I wont be able to drive it for another 6 weeks.... When I get her on the road, I will be doing some testing though. I'm going to record what the pressure is with and without it.

Guys im having similar problems, i installed my t04b and i had smoking problems at wot, now i added the restrictor and saw the opening was too small, so i drilled it out to 1/8". The smoking problem now comes at idle, and only when idling for more than like 2 mins or so, otherwise, no smoking neither wot or idle, but when it sits for a while then reved or taking off it puffs burned oil. Also my spool up sometimes is at 4800 and sometimes it gets full boost (15psi) at 4k. I know is not too much oil cuasing the slow spool because this happened without the restrictor and with the original tiny(nondrilled)restrictor, and has continued after restrictor being drilled to 1/8". I have my PCV to the stock location and crankcase vent line to the intake with a filter in between. Any help please, this thing is driving me insane i hate that smoke!!! Thanks
