I was looking at the back of the block, and noticed, unlike the 420a block, theres no place really for me to grab feed oil for the turbo. My ? is what are others doing. I would perfer not to run a sandwich adapter. thx guys

What year block are you using? The 2.4 has a 3/8 NPT port on the back of the block just as the 420a does for the stock pressure switch. I currently run my turbo feed and oil pressure gauge off that port. Depending on what year it is, it may be closer to the bellhousing, or near the water jacket NPT fitting.

early, 99? i belive, i run my 420a off the same one pictured in red, but i didnt see that one on the 2.4 block, i do however think i saw a small plug wher the blue circle is, ill investigate, and use that one if the other doesnt exist. and pressure/flow differnces other then loctation?

See that vein on the back of the block? That is the primary oil galley. Does not matter where on that vein you tap from. The plug you are speaking of is likely the water jacket plug, not an oil galley.

Post a picture of the back of the block. I will draw an arrow for you heh.

Here is a pic of the back of my block.

I don't have the red one circled, but the blue.

It just depends on the generation of EDZ block. Around 2001 the oil pressure sensor location was relocated closer to the bellhousing. 1st gen EDZ blocks will have the location shown in my photo & yours Psycho.

Thanks for throwing up your pic.

thx code4 and psycho, heres mine..



looks like im deff pre 2001.. i have the blue one circled in code4's pix. i circled mine in red (in my pic). the red one in my pic is what i want for oil, and blue one in my pic is the water correct.

Psycho, what color did you paint your block? is that satin black? im trying to figure out if i want mine gloss black or satin..

That is weird... never saw an application with a plugged oil port. Did you pull it from a junkyard that way?

You are correct, that is definitely the source for the oil and the other near the freeze plug is the water jacket.

it was terrys 2.4, i think he plugged it to paint it.. just my theory, its what i woulda done lol. I was looking around and making a list of ?s to ask, and this one was at the top, i figured that was it, but, wanst sure lol

It's Satin.

This should probably be added to the 2.4 tech in the wiki. I didn't know where I was getting oil from either. Very helpful!
