View original topic: Full Flow not cooling- or flowing?

Someone please help. Full flow oil. Shows good pressure and increases when engine is revved up but the oil temp is not rising. Oil in sump very hot but it just doesn't seem to be circulation through the engine. Im confident I have everything routed correctly. I'm simply stumped...

You are not full flowed.
You are hooked up to the stock oil cooler ports with an adapter.
A spring and piston control the flow to those port. If some thing is not right, spring, piston, oil pressure, oil weight ect then oil may not flow there.

Many thanks. I had someone tell me I have the adapter connections backwards. Any other solutions to offer?

Do a real full flow.

Install a flow meter in the oil hose. If you have a blockage you could have oil pressure without good flow or none at all. Check eBay $25.

Doesn't a "real full flow" require tapping the case? Or can I do the in/out from an aftermarket pump? If so, what do I then do with the adapter ports?

Also- I will purchase a flow meter. Looks like a good tool to have regardless.

I had a 69 Bus with a full flow filter/cooler modification, the oil was coming from the oil pump. It was OK until I encountered cold weather. I lost all the oil when the filter split open at the seam form very high pressure caused by the cold oil. This problem is much less likely when the connection is made with an oil cooler adapter, which is protected by the oil pressure bypass valve.

Please post your flow measurements, the flow is pressure and temperature dependant.

Success!!!! It was indeed routed incorrectly from and into the adapter. After switching in/out, the flow was perfect. Pressure and temp all where they need to be. Thanks for the feedback and assistance!
