Title says it all.

I have a 93 Honda Accord EX that I'm currently trying to restore for sale and a part of that involves effacing the leaks it has.

I have replaced the o-ring on the back of the oil cooler and oil sender unit/pressure switch since the latter was leaking too, anyway.

But since I've done that and have checked underneath I'm sad to see that there are still a few droplets of oil there.

Here's a pic:



So what I need to know is how do I service the cooler itself?

I have read somewhere that the cooler has more than 1 o-ring. Besides the one on the back/bottom of the cooler there is supposed to be one in the middle. Anyone know of any good links or can write down the procedure for replacing that other o-ring?

Again -- I DON'T HAVE AN ISSUE WITH THE BACK O-RING, THE ONE THAT TYPICALLY CAUSES PROBLEMS. AND MY SENDER UNIT IS NEW AND DOING FINE.

Thank you.

 

Anyone? Or any Honda mechanic here? Anyone with any clue?

This is a very minor leak. It's nothing drastic. But since I went out of my way to replace the oil pan gasket (as you can see above in the pic -- the orange is the new Felpro gasket), and since I replaced the back O-ring and the oil pressure switch, I'm now "all in" and have taken this remaining bit of leakage personally. It needs to go. I'm trying to get this to perfection.
