93 old 3.3 oil in rad. 75k. All fluids except rad are good. Help
Believing cracked water jacket?
It could be trans fluid. There is a trans fluid cooler in the radiator that might be leaking.
Even when trans fluid is still pink? Smells Polly not sweet or like trans at all
Intake side of heads will leak oil into the water/antifreeze if warped, cracked, or the gasket is blown. I assume aluminium heads. Has it ever ran hot would be the next question that comes to mind.
A good way to tell is to take off the rad cap when ITS COLD ONLY. Crank car. Wait about 5-10 mins. If water comes out of the top of the radiator, pretty good bet its the heads. Sorry bro. Good luck to u.
