HELP homemade hpop setup problem

[B.A.D Performance]

I found the problem I think. With the t444e resivoir I have it didnt have an oil passage for the oil to flow so the port was blocked off. The build up of pressure in this area blew a hole and the gasket causing it not to build pressure. I think I figured out a way to reroute the oil flow. Should know if it works tomorrow when I get new mounting gaskets

were you saving the SD reservoir for some reason?

 

[B.A.D Performance]

No not really. Just trying to get this pump set up figured out before I sell it

 

[mandkole]

I was just surprised you didn't use the res that came on the motor instead. Hopefully, you've gotten it figured out...

What do you mean? You have to use a t444e resivoir to bolt the halidex to

I would look at using the early HPOP to match the early rez and just dump the IPR in to the front cover.
but I have never had an early setup to inspect how the check valve IPR works so I am assuming it just dumps to front cover

Well I got the truck running but now I have a new problem.
With the halidex pump hooked up to the stock pump the truck will not start. The ipr goes to 65% and the icp only builds 200psi. I thought maybe the halidex pump is sucking the resivoir dry so I put and oil pressure guage on the resivoir and got 20 psi while cranking.

Now if I bypass the halidex pump the truck fires right up. I double checked the direction of my check valve. It was correct. The halidex seems to be building pressure. Is there something im missing here?

This is a picture of my setup. I only had pictures of other setups to go by. What am I missing?

So how exactly is this setup routed? Does the haldex feed the stock hpop, or the opposite, or something totally different?

 

[B.A.D Performance]

The haldex feeds the stock pump at the rear port on the back of the stock pump

 

[B.A.D Performance]

Heres a pic of it on the truck. Dont mind the plastic tube on my fuel regulator its justs for testing

 

[ghohouston]

And is that how everyone else has done this? I'm trying to make sense of why it's not working right. Can you isolate the haldex and check it's pressure? You said something about a check valve, is it there to keep one pump from pulling the oil from another or???

 

[m j]

check valve stops the hpop oil from exiting out through the haldex

 

[B.A.D Performance]

I just copied pics of swamps setup. The check valve keeps the stock pump from back feeding through the haldex pump

 

[B.A.D Performance]

The only thing I can think of is the haldex might have blown a shaft seal. When the 2 pumps are hooked together the stock hpop is bypassing oil through the blown haldex seal

 

[ghohouston]

Like i said, i would check what kind of pressure the haldex outputs when isolated

 

[m j]

also check the pressure relief circuit. the oil is going somewhere, but it does sound like you damaged the haldex when you dead headed the ipr circuit

maybe check that the pumps are spinning and not slipping on the shaft.

 

[B.A.D Performance]

Thats what im thinking. The haldex was getting extremely hot when I bypassed it.

Did you reverse the pump housing so it goes in reverse?
