Where can I find an O-ring that goes between Oil Cooler Adapter and pump?

Mine has sprung a leak there, can't seen to find them listed anywhere.

Thanks

Earl brown has them on eBay $5 plus $3 shipping for a thicker gasket.

In a pinch, you can use the gasket from an oil filter, not a permanent solution, but it can get you home.

But then again, so can just removing the adapter and putting the filter directly on the housing.

that ring will fail , easier as yu posted is just unscrew the adapter nut , push cooler aside and screw the oil filter back on

That one isn't thicker than stock. It's just a 146 (or 147, I can't recall for sure). The GM groove in the sammich adapter isn't the right dimensions for a o-ring of that size. A conventional sized o-ring should stick up well below flush so that it gets 'squished' into a square and has good contact on all four sides. The groove GM cut leaves as stock sized o-ring just barely above flush. Nowhere near enough to deflect the material and load it against the sides properly.

That's why it's a VERY common place to have an oil leak.

As long as you're buying a bunch of performance parts from RJC Racing anyway, you just as well have them include one with your order. lol
