For those of you with oil pressure gauges.. what is your oil pressure at HOT IDLE? Also, where is your sending unit?
This location for the sending unit is a little tight with the cooling fan shroud. It fits, but barely. If I was to do it again, I probably would have routed it all the way to the battery tray area and mounted it there. But it's all good!
i use 5w-30 as well, cold driving i get up over 90 psi, but at operating temp it goes from 18psi hot idle to 65 psi hot cruising
Mine reads the same as Fox's. I think 63 cruising. 80 something on cold start. Idle around 18. Mine is mechanical and is plumbed into my oil filter relocation setup.
I'm pretty sure that mine is tapped at the head. Reads 40 PSI cruising on the highway, 80 PSI cold idle, 8 psi hot idle.
hot idle tapped at the block behind the ac compressor or at a remote oil filter will be ~ 20 psi, 65 at cruise.
So I'm wondering what that means if mine is exactly 2 psi lower at both readings. Ring wear?
My gauge has read down to 25 PSI at idle and usually runs at 80 PSI on the highway and I am tapped into the block behind the ac compressor. I am running a FAZE electrical guage on my 3L.
When the engine's cold I bury my electric gauge over 100psi when cruising
