After hearing what you guys run for oil temps I better get out to the garage and do some ducting! I'm in the 110-115c range! I think I'm doing damage to my oil control o-rings because after decelerating down a long hill I can see a little puff of blue smoke in the rearview :( Seems to only do it when the car is up to temp though. HOPE it will go away once I get the oil temps down to ~ 80C.

Oh yeah, nice oil coolers you have their! https://www.nopistons.com/forums/pub...IR

HOLY CRAP!!! That's pretty high. What type of fans do you have? And more important, what temps do they come on at. When I got my fans to turn on at an earlier temp, the water temp as well as the oil temps dropped considerably....like I said 85 water and 95 oil. Now it's 85 water and 75 oil https://www.nopistons.com/forums/pub...IR#>/blink.png

I did some work to it last night and got the temp down to 90c after a hard run on the freeway https://www.nopistons.com/forums/pub...IR#>/smile.png

I'm still looking for a oil temperature switch to turn on the oil cooler fan. If anyone knows where I can get a 1/8"npt switch that will turn at ~180-190 let me know! I'm having a hard time sourcing one. I have it wired to turn on with the radiator fan at 188f (water temp) right now but it's not working because the coolant temp is always a TON cooler because it gets more air while cruising down the road. What do you use to turn on the oil cooler fan?

Also I'm not sure if it's possible on your cars but it's best to mount the coolers so the in/out fittings are pointed up to eliminate drainage of the cooler while the car is off.

Great topic!
