I threaded my front oil cover on the side just next to the omp...worked out really well...I will post a pic when i get home

I like to use the Atkins method of threading the front cover where it kinda goes horizontal below the OMP. There is a relatively flat and thin area that takes a 45° barbed NPT fitting for the oil return of a Camden. I'm sure it would work with a turbo as well, depending on size and location/position etc.

Yeah, I was talking about the drain on the front cover. I didn't want to use the typical push on hose. I wanted to use a AN fitting down there........... but didn't want to pull the front cover off to tap it :(

Here is where i tapped and threaded mines at i think this what jeff20b is talking about...

Is that for the pressure or the drain?

Reason I am asking is the OMP supplies pressure since you are next to it, yet the OMP does not supply it to where you are.

nah that will be my drain coming off the turbo...I'am no longer using the omp...Im I have blocked it off but still retain the gear inside to build up pressure to feed oil to my front stationary gear and turbo...

I heard you can take the whole gear and whatnot out and not suffer any losses.

Then again I do not know where the oil flows through the block. I would do what you say just in case I believe.

I have studied that front iron front and back...i have extra 12a irons here that im thinking about cutting in half to see where all the passage ways are going and where the pressure is coming from

How much of an incline does the return line need to be on? my hole is drilled just below the top bolt hole for the omp on the left of it. My return line does "S" a little bit to clear the manifold but it looks like it is downhill just not over convincingly. i will post a pic as soon as i can

yetterben 06-19-08 12:01 PM

All that matters is it's down hill with as little bends as possible!

Jeff20B 06-19-08 12:06 PM

I should have said the flat nearly horizontal part on the front cover a couple inches below the OMP. That is where my oil drain is. Tteddy used the stock location, which is a little less friendly, as John has found out, having to do an S shape. Mine is long and curved but all downhill. It's probably a little too long actually. Gotta trim a couple inches.

thanks for the information 20b

So I went ahead last night and bought a 1/4" Brake line and it screwed right into the Brass "Bung" in the block and it fitted right onto the turbo with a couple couplers. I was told this line can handle 100 psi so heres hoping.
As for the Dizzy obstruction I have it so I can retard back to the center of the adjusment screw and I can go right to full advance I just cant retard past center of the adjustment screw.
Let me know what you guys think

yes the gear can be taken off...MannyVidal another forum member here did that or this mod to his front oil cover as well
