Help me on my quest for 20+ psi on a BLT

[Rengar18]

So i've been trying to tackle this for some time now and I still cant get all the leaks fixed.

Currently I get about ~3 psi with the tester hooked up to the throttle body pipe and similar results with it clamped on the turbo inlet.

So far i've done:

TB Shaft Seals
New injector seals and orings
RTV'd my TB gaskets
Taboo Speed shop vacuum line removal (minus the EGR blockoff, I just rerouted the hoses, ordering a blockoff Monday)
New biss/cap
New gasket on my compressor cover
Rebuilt my 14b two months ago
Double clamped all my IC hoses


I test it with the air compressor set @ 20psi with the intake valves closed spraying soapy water all over (also have the pcv hose coming out the IM blocked when testing) and i'm getting the same results. All I hear is air in the general IM/TB area but I dont feel any air coming out from any place and the soapy water doesn't reveal anything.


Only thing I can think of thats still leaking is maybe the EGR since I dont have it blocked off with a plate just simply rerouted into itself OR the IM manifold gasket. When I rebuilt my motor 5 months ago I reused my old metal one and sprayed both sides with copper spray.

Also my compression is 150 150 150 160 and a leakdown came out fine. Give me some suggestions guys, thanks

You making sure your doin the blt at tdc with all the valves closed?

TDC doesn't mean all the valves are closed. It just means the piston on cylinder 1 is at the top of its stroke.

Leaking from intake manifold to head?

Is it leaking from the breather line on the valve cover?

it doesn't matter what position your camshafts are in for the BLT - as long as you are timed correctly.
make sure you are testing after the turbo, as sometimes the turbo leaks internally and bubbles up thru the oil return into your crankcase.
also, only a FACTORY OEM MITSUBISHI PCV valve will hold boost. otherwise, you need a one way valve inbetween the valve and your intake manifold.

check that EGR system
mine was leaking pretty bad so i just blocked it off

there is a lot of vaccum houses from EGR system under the battery check there

When I do a blt it leaks from the valve cover breather.

Does that mean a bad pcv? Doesnt that also mean bad rings?

Bad pcv.

Try blocking it and do blt again and see what happens.
