Oil Pressure drop after installing turbo.

Oil Pressure drop after installing turbo.

I installed my tee to the back of the block where the oil pressure sender goes
Block -> ^oil feed line -> oil pressure gauge and at the bottom of this tee is a blank that screws in to the hole, and it's leaking oil..
Can this leak directly at a pressure source cause low oil pressure?
Oil pressure at idle while warming up after the cold start 25psi, after driving for 20 mins hot idle is at 10psi and sometimes lower, no knocking, no other noises, sounds and runs great.
it's definitely puddling oil, quite a bit of it.

Re: Oil Pressure drop after installing turbo.
Think for a second. You answered your own question. The leak is interfering with the oil pressure gauge reading. Fix the leak.

After reading, you're right.
I also did some reading stating I'm bleeding most of the pressure off to the turbo as well..

Re: Oil Pressure drop after installing turbo.
Yup....I have seen this before but never quite understood why some people install the gauge just before the turbo, Install the gauge (preferably in the cabin so it can be seen while driving) at the block itself that will tell you what your motor is putting out

Oil leak fixed..
Added 1qt of 20-50, and it brought idle pressure up to 10psi at HOT idle
i'm thinking it has to be the tee..
I'm 10psi per 1k rpm at hot up util 5500rpm where it flattens out at 50psi

Re: Oil Pressure drop after installing turbo.
What brand of gauge measures the pressure? Do you have an oil cooler? I have bad dreams when the pressure is below 20 psi at idle...

Re: Oil Pressure drop after installing turbo.
It's typically put at that location to read what oil pressure the turbo actually sees, not the entire oil system. It's right at the oil line. I'm confident he'll see higher oil pressures if the gauge were on a more precise location somewhere at the block or even the cylinder head
