I attempted to post this two days ago but something failed.

i was overheating and got and stayed hot, I found a cracked expansion tank and replaced it. Before I found the coolant in the oil I was starting to use fluid on short trips and thought it was from the crack in the tank.

So I replaced and still have pressure on the coolant after a night to cool,. I may going to replace the thermostat but looking for suggestions while I have the car apart to look for.

Will look at the oil cooler as possible point that the leak is..

Other other suggestions would be great.

 

Head gasket if you've overheated the block.

 

There is a seal on the oil cooler that separates the oil...from the coolant. That seal can go bad and let the two mix. Maybe check that first?

 

I have a new thermostat, oil cooler and seals on order...that was the plan. thanks.
