Modification suggestions...

Okay, I'm a machinist on the side, as a part time business. My garage is a regular machine shop. When I buy a used vehicle, I always tear it completely apart and see what makes it work, and always look for places improvement is possible. (Somebody already beat me to fixing the STC fitting, but that's an example of what we're looking for.)

I haven't been into the heads yet, but if I'm correct those standpipes appear to be plastic? (Modifying the entire upper HPO system is a thought. Unless people consider it reliable enough, it wouldn't warrant brass or stainless stand pipes?)

I'm also making an easy to install oil pressure manifold that screws into the location for the factory oil pressure switch. It will have 2 fittings at 1/4 pipe thread, and one at 7/16 x 20 for the factory switch.

Looking for idea's......equipment standing by.

The factory oil psi switch/sensor threads are metric.

That's what I assumed. Checked with a Snap On thread gauge. 7/16 x 20 tpi. Took the sending unit by International, they confirmed it. (This is the pressure switch. Temp is different.) The tap also threads nicely in the oil coolet cover, no resistance.

My bad, sorry, I was thinking EOT sensor. I just checked the oil pressure switch, your right it's 7/16-20.

What have you come up with on the oil temp sender? I'm thinking that one is metric, but haven't checked it yet.

The EOT is M12 X 1.5. Same thread as the fuel pressure test port plug.

You gotta wonder what engineer(s) decided to use both metric and SAE threads, on the same cover plate!
