Oil temp reading
« on: June 16, 2018, 08:34:47 PM »
So my oil temp reading on my bost is in the range of 150-170, I have a Thermostatically controlled engine block adaptor thats suppose to bypass my oil cooler until 180 then opens fully. My question is why am I seeing 150-170*, My oil cooler is a 3x25 on my 502. Do I possibly have a bad sender? My sender is tapped in right at the remote oil filter?
Any help would will be greatly appreciated, ill get pictures of my setup tomorrow. TIA

How much oil? How much HP? how hard did you run it? Is the oil cooler plumberd on the cold side, or the hot? (should be the hot side)…


What was the leaving water temp?

9 qts in a 10qt pan, 500ish... Im in it between 3k-5200 rpms. They have the sender on a t, where my oil pressure gauge comes off the block. Not the greatest pictures but i hope it helps. It seems like its got to be after its been cooled. I know the pan is the best place, but is there any other ports on the zz502.?

I am going to sound like a dick here, but hang with for a moment....


Lose that brass bullshit.... All those tees and fittings with the gauge and the pressure sender, make that shit go away....


I don't see a temp sender anywhere.... Is it reading the temp before or after the cooler?

The cooler should be plumbed like this crude diagram....

If your oil temps are -/+ 10-15F you're gold. To many people think that having low oil temps is a good thing and it's not. Oil needs to get hot so it can thin out, remove moisture, clean, and remove acid buildup. I'd personally like to see oil in the range of 180-200F
