Oil cooler bits have arrived!
-12AN fittings (LARGE!)
25 row cooler core.
Fitting in place
I have also tested the motor for head gasket issues with a basic chemical block tester. This was placed in the swirl for and sniffs coolant for hydrocarbon. Test liquid stays blue if OK. Turns green or yellow if HG has failed. I did the test twice so fingers crossed all ok.
These pics are AFTER so staying blue looks to me like all is ok. Fingers crossed my over heat issues are airflow, oil temp, or tune related.
