i change the seal 3 times the last one stagered gap and the exhaust housing still filling with oil and the car smoking pretty bad.

Maybe a bad center section where the seal run? Sugestions please.

I sell this turbo to a friend now i have to respond.

Are you changing the seal yourself, or having a professional do it?
If your doing it yourself maybe your making a mistake....

Also how does the feed/ drain set up look?

precision reccomends a -3 or -4 feed wide open with no restrictor, but it has been proven time and time again that they are wrong, and they NEED to have a .065 restrictor on them.

And your return line should be a -10 that has no flow restrictions, no kinks, and only a smooth bend, also be sure the return enters the oil pan above the oil level.

My bet is it has something to do with the feed or return line, and not the seal....

yes is a shop

return new s/s braided 10an

.060" oil restrictor and 4an line.

the guy said to me that maybe is the center section.

Not if your return line is not hooked up correctly. you have a lot of other factors here that could easily contribute to the issues that you're facing. Stop repeating the fix of the symptoms and look to the over all problem. Start diagnosing what's being suggested.

1) Check oil feed/return line for the correct size or any kinks within the system

2) make sure no 90 degree angles are on your return line

3) check oil pressure at the line, to see if a restrictor is needed. listening to general info doesn't help.

without that, nor pictures of the return line an oil feed at multiple angles, no one can help.. seriously.

it's normal the fitting on the pan spill oil when the line is disconected?

because all the time you disconect the line the oil come out and not stop for
a good time.

i have no camera i try to put some cell photos tomorrow.

That's not what we mean. oil pressure while the car is running. do you have an oil pressure gauge? if not, perhaps you would be better to get one installed or check with a gauge at the line and crank the car as though starting it.

carlos8

shodan, i put a gauge in the line at cold start is at 80psi and after warm up
35-40psi.

sound normal those numbers?

TheShodan

80psi is a little high. Check the routing of that return line, and possibly the use of a .065" restrictor. But need to see pics of that line first

carlos8

there's a possible that the center section it's cloged?

if you blow air with your mouth by the oil feed it's hardly to pass?

.065" restrictor it's already installed

Center section passages don't get "clogged" in the traditional sense because of the way the oil is splayed in the system.

I think I'm done.. I've given the suggestions required to ensure what needs to be done. That doesn't mean that there could be bluing on the shaft, showing that its warped and a new sealing ring may not be installed.

Until you show the pictures as otherwise suggested to at least narrow things down, there's nothing more we can do. No one can assume that simply changing a sealing ring on an entire cartridge that was taken apart was done correctly.

Where is your bung on the oil pan. It needs to be close to the top. Like theshodan says pics are needed.
