Oil feed T piece from idiot light? what is this part?

[spence88mph]

Hey everyone, I need to connect the turbo's oil line to the oil feed and I know there's a 'T' part you can get that screws into where the idiot light is and gives you a banjo fitting to go off to the -3AN line. Then you screw the sender back in? I dont know what this part is called or what the thred is that the oil light sender comes out of etc? Can anyone please help? (I've serached high and low through the forums) BTW this is a Carrera 3.2 engine. Cheers Spencer

Hello,
I see what ya mean. I looked over the PET diagrams and it doesn't show it.

You need that whole setup because there is a ball bearing used as a flow restricter in that fitting. Otherwise you'll feed full oil flow to the Turbo bearings and blow oil past the seals. Ask me how I know this! The diagram doesn't show that either. You may want to call Pelican to help out with this.

Spencer asked something in a pm, and I figured I'd post the same pic I sent him, in case someone needs it in the future.

Does this one have an oil restricter in the fitting? If you send full flow to the turbo, it will overflow the ability of the scavenge pump to keep up with it. Did you make this yourself or receive it a kit from someone?

Thanks Les and Jerry,

Jerry I posted this before I PMed you, I was hoping I could get the part yesterday before the shops shut hense the urgency!

Les I dont think it does have a restrictor, I thought the -3AN line would be enough restriction, we'll soon find out!

If anyone can tell me what the thread sizes are on that t-piece, I would greatly appreciate it.

You'll know if it does not restrict enough!! You can make a little extra money on the side as a mosquito fogger!

long story, and someone else's turbo starved with a dash 3 line and restrictor on the feed line on a turbonetics.
so I, and a friend, and another guy I'm pretty sure aren't using one now, also no check valve either. But, my return line runs to the sump, specifically, the drain plug. (3.2)

No weird start up oil back up issues so I assume it's working well. It's been 18 months and I check the turbo often.

Interesting, I have the stock line on mine. The line is pretty large. When my Turbo started blowing Blue smoke I called Stephen at IA and he asked me about the restrictor and had I left it out. Sure enough I had, dropped the ball back in and no problems. -3AN oil starvation sounds worse. I don't know, but I think mine is the stock setup and should be available from somebody. I'll look in Alldata and see what it looks like.

Hmmm, nervous about using the -3 line now! I have the drain through a -10AN line to the sump plug. Merv has been running the -3 for quite a while on his Gt35r, maybe they dont need as much oil as the turbonetics.

you can always add the restricter after you determine if you're over-oiling.
I would bet the rate of return on a 3.2 oil pump is different than the pump that returns a 930s turbo oil.
the way we have it, the 3.2 pump is sucking it up at the sump.

Yeah the other guy is not running the restrictor.. Oh by the way I will be down your way next week near panama city

you are using a kkk? or a ball bearing turbo then yes if you use a standard bearing and use the oil pump sump to draw the oil you will be good to go

[spence88mph]

Hey Ben, can you please tell me the threads on the T piece, they look like m8 or m10?

[spence88mph]

pelican have the part for the sender as 911-606-230-00-M85, the M# is usually the size, I dont think there's such thing as M85 so M8 should be safe.

Hi,

I'd keep checking. I could be wrong, but I think that fitting is more like 10 or 12mm.

[spence88mph]

ok I found out, it's M10 1.0 thread.

All good!
