Rebuilt Turbo dripping oil w/ removed charge pipes
 

After installing a rebuilt T3 from Westcoast turbo, I noticed oil dripping from the compressor outlet of the turbo. The charge pipes are not connected and my -3AN line feed pressure is 25 @ idle, and 75 @ normal driving. Should I get a restrictor valve, The return line seems fine, could I be wrong, and lastly does this indicate bad turbo seals? Im almost there please help.

Yes- I'm running a .060" on my t3/t04. You've probably blown a seal at his point.

Thanks for the input M2cup. Im gonna get one. But do you think Ive blown the seals, being that the charge pipes were never connected, and the turbo never built boost? The oil pressure is really too high and was leaking past the seals, but are they that fragile that they are already damaged? This turbo was rebuilt with new seals. I really hope not. But if so Im sure I can get me a rebuild kit. Right?

Re: Rebuilt Turbo dripping oil w/ removed charge pipes
 

running a turbo without the charge piping connected is a great way to blow up brand new turbos, they spin wayy too fast with nothing to slow them down and disintegrate. Do you have any shaft play on it? Particularly in-out shaft play? And yes, you should have a restrictor valve on the turbo, it doesnt like to see 75psi oil pressures, thats too high. A t3 only needs about 10psi oil pressure to operate

Ill check, The turbo wasnt even spinning. Im gonna get a restrictor though.I was more concerned about the oil leak.

Re: Rebuilt Turbo dripping oil w/ removed charge pipes
 

up to 40psi of oil pressure if fine but when your running 75 you will blow seals quicker then you can say oh ----.

Re: Rebuilt Turbo dripping oil w/ removed charge pipes
 

I just checked my turbo and there is no shaft play. Thats good. One more question, When I put the restrictor on the turbo, wont I have to put one on the oil pressure sender to get the same reading that the turbo has?

Re: Rebuilt Turbo dripping oil w/ removed charge pipes
 

a restrictor really isnt going to do you ----. hook up the charge pipes or take off the turbo untill your ready for everything. the turbo actually uses the boost pressure to help seal the oil out of the compressor housing. no charge pipes= no boost=leaking oil.

I didnt know that.

Re: Rebuilt Turbo dripping oil w/ removed charge pipes
 

A worn out turbine-end piston ring or the groove it sits in is the most common cause of oil leakage on journal bearing turbos. Just installing a new piston ring doesn't always do the trick. If the groove was worn out, machining it larger and using an oversize piston ring is necessary. If you can move the piston ring in and out on the shaft even slightly, that's gonna be a leaker for sure.

Re: Rebuilt Turbo dripping oil w/ removed charge pipes
 

That sound logical. Im gonna use an oil restrictor because after some researching Ive concluded that 25psi at idle is slightly higher than some others. If this dosent solve my problem then Ill focus on the turbo itself. Do you have any reccomendations for rebuilding my Garrett T3 if I need it serviced?

Re: Rebuilt Turbo dripping oil w/ removed charge pipes
 

Yes, if with a 1/16" restrictor and a proper ½" drain you still have oil leakage problem, you can send your turbo to us. We rebuild it for only 125$ and after that it looks and performs like a new one and is covered with a 6 months warranty.

Thats good to know. Just curious, after you receive the turbo, how long before you repair it and send it back?

Re: Rebuilt Turbo dripping oil w/ removed charge pipes
 

LEss than 48 hrs turnaround time on all T series rebuilds.

Is that quick enough? 8)

hey blast while you guys are doing a rebuild can you take out off/weld up my external wastegate the right way. i dont want to ---- anything up. i'll be running a tube mani with a knock off 46mm waste

Re: Rebuilt Turbo dripping oil w/ removed charge pipes
 

You mean? plugging the internal wastegate hole in the turbine ?
It doesn't involve welding at all!
Just a block off flange does the trick for 25$ !

Ha, this is like the BlaastPerformance advertising thread. It's really a staged post. ::) That is a really good deal on a rebuild compared to the $250 norm. :y

I just try to answer some questions when i can.
I don'T even have time to make a posting.
I don't want, or need advertisement.

Re: Rebuilt Turbo dripping oil w/ removed charge pipes
 

I realize that, just I never see you post all that often. I was only joking. ;) ;D

ok thanks for the help blast, can i just weld a plate on my dp? I dont want to have another dp made? doesnt where the rod enters the turbo need to be block off too? thanks again
