Hey guys. I have some questions about oil coolers.

How do I plum to the engine? I'm using a sandwich adapter for oil pressure and temp. There are two unused ports in that adapter. Can I use those for the oil cooler? One of those ports would be for the supply, but where does the return go? It's an LT1 with a Moroso pan.

My other question is are there any problems with mounting the cooler above the engine in the hood scoop? I'm planning on securin the lines to the bottom of the hood and run them down the drivers side hinge then to the engine. I can't imagine there would be any problems with the location, but I thought I'd ask in case you guys know something I don't.

I'm not going to run a thermostat for the oil. I'm just going to tape the back side of the cooler for street use.

So tonight I loosed the Y pipe and wrapped the y pipe with headed wrap I picked up from autozone.

I took it for a spin, excited to see how much it lowered my oil temps. The result? Zero. Nada. Zilch. Not a single degrees difference. Oil temps went right to 220 while just gently crusing around. Then I got on it a couple of times and they went straight to 230+.

I don't get it. I thought for sure it would have done something.

What else can cause high oil temps?

Oil pooling in the heads and engine's lifter valley would cause higher oil temps as a smaller amount of circulating oil is handling all the heat from the engine. I'd check both heads and make sure the oil drain back holes are working properly, e.g., no debris blocking any of the holes. If you're using the engine valley oil baffles standoff tubes, I'd take them off as they tend to pool oil in the lifter valley and the amount of oil windage they reduce isn't worth it on a non-race engine.

If oil drain back isn't a problem, and you're not using the oil for any type of piston cooling, I'd next look at a partially stuck oil bypass valve in the oil pump. (You should have noticed a decrease in operating oil pressure if this did in fact happen though.)

Finally, I'd use a bore scope to check the Moroso oil pan's baffling to make sure that you are pooling oil behind a swing gate or baffle.

Hope this helps.

How do I check the drain holes in the heads? Pull the valve covers? And what about the oil baffle standoff tubes? I don't know what those are.

Oil pressure is very good. 40 -60 hot.

I know I have over filled the oil by probably 1 quart. Maybe I'll drain some and see if that helps.

Maybe I should just install an oil cooler.

Thanks for your help. I've got another track day next week.
