I installed an oil cooler with thermo plate about 2k miles ago and it's leaking. I was scared it was a hose fitting or the thermostat itself, but after a quick look it appears to be leaking from between the sandwich plate and the factory oil cooler. I'm going to reinstall and I bought a new O-ring just in case I actually need it. My question is about the O-ring orientation. Both sides are not the same, and I don't know which way it's supposed to go or even if it matters.
