I agree with Griff. Check the oil cooler inlet first. Take both hoses off and check with a flashlight from the bottom up to see if there is debris blocking the capillary tubes. If there is debris, clear it and see what the debris is. If it's rubber impeller vane pieces, you will know. I found a complete vane in mine after a shop "allegedly" flushed all the hoses.
Most times on the hose, the temp will be close to normal, at least mine does. Curious, but what temp t-stat are you running? I run 160* in mine and the motor runs between 170-175. 180* isn't hot by any means. Personally, I like a little heat in the motor.

I am running 140F thermostats and I consistently see no more more than 150-155F water temp although my oil temps spike 180-190F when I am doing a speed run.
Ps-I did NOT note any increase in oil temperature when I was idling around and my water temp started to rise???

that seems like a really small oil cooler to me. maybe not your problem but if you are making 500 plus hp this is the size i run.

Thanks all...engines are built by a pro and I do see about 190F after a solid speed run but water temps are always in range (except as noted this time).
I can see that this is going to require some contortion to get back there. I wonder if I can snake a remote camera down the water hose for an inspection?

Before getting too deep into it. Take her out again to see if the condition is still there. Something may have been blocking the intake.
Over the winter… add some water pressure gauges to the system. They’re important to have and will alert you to problems before they become a big thing.

That is your oil cooler that you circled. All you need to is pull off the water hose and feel inside the end of the oil cooler with your fingers for any debris. It is only about a 2-3" deep before you will touch the front plate with the cooling tubes.

Can somebody recommend an analog water pressure (or flow) gauge to put inline in my set-up?
