Dan Olson oil cooler

[Snowboat]

I was calling to get the address for Dan Olson Racing Products, so I could send my oil cooler in for a rebuild, and the phone number no longer works. Is 209 251 6001 the correct # or do they have a new number?

I put new o rings in and buffed the corrosion off, but it still leaked water into the engine oil. When I tested it, I even warmed it up in boiling water and ran 25 psi of regulated air to it, no bubbles when immersed. Tired of tearing the engine down. The problem went away when I removed the cooler. Thought I would let the experts test it this time, with a lengthy note about the problem enclosed. Any suggestions. I can live without the cooler, but it looks cool.

Hi Snowboat, I have a job in a power plant that uses a very large version of your cooler, they use plugs to block ff the leakng tube.I am curious what they will do to fix yours.Please post the fix when it is returned.I have 2 coolers from olson, one for a mark4 block and the other is for a gen 5.The mark4 cooler is leaking and I plan to call them to get a o-ring kit.
