Oil line BLEW UP!! backwards?

[PorterzSupra]

On the turbo block the line running from the top of the oil filter adaptor is the main? And the oil line taped into the oil pan is a return? Thats how I have it hooked up but I think its backwards because I ran 60 PSI and it blew apart =( is the top a return and the line out of the pan a main?

 

[jdub]

They way you have it is correct...sounds like the line or oil cooler is clogged up.

 

[PorterzSupra]

I am running without a cooler for this start up

 

[PorterzSupra]

The oil filter blew the seal apart, its either backwards or the pump is messed up!! I did the shim 8 MM like it said. I have the top adaptor line running into the top of the turbo and the oil pan line running from the bottom of the turbo

Mine will run at ~60psi when I very 1st start it up and its below freezing out. But after the motor warms up the oil pressures are very confidence promoting.

But, you just ran the cooler port on the thermostat housing straight into the oil pan? I don't think you're supposed to push oil at such pressure directly into the oil pan...

 

[PorterzSupra]

I herd a big pop I think the turbo seals blew out!!! what is wrong with my pressure here!!!??

8mm shim.......... :aigo:

 

[mkIIIman089]

What guage did you look at when you saw 60psi?

I see ~6kg/mm^2 at startup and i'm not exploding my turbo seals from it.

If he's shimmed it solid like I suspect (coil bind) and is running 20w50 he could have seen 160 psi on that start but as soon as the filter pops the pressure drops.......

:ugh: Uh....what did you do?
Do you have a pic of this re-engineered oiling criss crossing "fudge-a-ma-call it" set up?

 

[IJ.]

Another "Guess" on my part is he's used a solid shim without the centre hole!

Yeah, but what about:

"I have the top adaptor line running into the top of the turbo and the oil pan line running from the bottom of the turbo"

It sounds to me as if he took the oil cooler lines and is feeding the turbo with that, but I'm tired so I don't know WTF is going on.......

LMAO @ *.*

also @ "fudge-a-ma-call-it"

Jimi: No idea really!

This is the same guy that asked the serious question "Where are the head bolts?" so who knows.....

I was just having a guess at what he's done based on the symptoms

(A bit of a clue is Turbo's DON'T have "seals" as such like a rubber lip seal they're a combination piston ring seal and a labyrinth so there really isn't anything to "blow")

On the turbo block the line running from the top of the oil filter adaptor is the main? And the oil line taped into the oil pan is a return? Thats how I have it hooked up but I think its backwards

Um.....after re-reading that I'm SURE he is using his cooler lines to feed the turbo.......WOW

That is a BIG NO, Thats for the cooler, What did you do with the stock turbo feed and return on the block?

 

[PorterzSupra]

its a NA there is no turbo feeds, why is using the oil cooler lines a no no? I read you can shim up to 10 MM I only did 8!! My guage went 80+ and the filter gaskets poped. my turbo poped im super fucked it was a expensive T6 brand new turbo... I used the washers with the holes in them and measured to 8 mm exactly (happened to be 8 washers) why does it say u can do that on here???

 

[jimi87-t]

I have no clue with the shimming, but the cooler idea, where did you get that info. IIRC, the cooler line does not flow 100% of the time, there is a psi release to send oil into the cooler, plus when it does flow, it is not enough for the turbo.

 

[supra90turbo]

There is literally TONS of info on the correct way to do an NA-T swap on mkiiitech.com

 

[jdub]

Oh Man :wtf:

I just re-read your 8mm shim on the pressure relief valve spring on the oil pump...the most you want to do is about 90 thousands thickness. That about 2 washers worth and will give you about 10 more psi of pressure.

Using 5-30 oil, that gives me about 20 psi (warm) at idle...and about 40-50 at higher rpm. If you used 8 washers....and if you're using 50W oil....
supra motor :bigun2:

 

[IJ.]

See the pic below there is only 1 of these that's NOT on an NA block (the one in front of the filter mount) and you can use any of them as the Oil supply for a Turbo.

I said in Shaeff's thread on shimming the pump that 5mm is the maximum safe thickness......
(I run 4.8mm)

No Where in the sticky does it say to run 8mm.
