I have a six engine oil cooler marked “leaks”. Anyone have experience fixing the same or is it a loss. Appreciate any help including source.

I’ve seen valuable oil coolers (from historic race cars, etc) sent out and fixed. Then they develop a leak in another spot. It becomes wack a mole. I would bin it and move on.

I have many 911 engine oil coolers that leak. I have kept them but never had one fixed. They can be modified to make an engine oil filter console.

Kinda figured that was going to be the answer……….
So another question, how do you pressure test one….( not the leaker).

Couldn't find that brand, but did find this one:

$130 doesn't seem bad.

Try Pacific Oil coolers. Mostly have experience with my airplanes.
