I'm still chasing an insidious leak on the passenger's side of the engine. Can anyone confirm for me that the flared connections for the remote oil cooler adapter lines (not the end with the crush washers) doesn't take o-rings? I don't think they do, I believe they're like all of the other flare fittings I've seen that compress the flared connection, but this looks like it might still be the source of my leakage.

I'm having a tough time getting the source isolated. I don't relish the idea of laying completely under the front end with the car running and up on jack stands.

Thanks for any and all help.
