Weeping oil cooler lines
Gents/Ladies,
Is it common to consistently have oil residue on these fittings? Anything to be concerned about? It be by the oil filter sandwich. I don't have any drips on the floor, but when I put my fingers to it, there will be a minute amount of oil on my finger from there. Got a track weekend coming up at the end of this week.

I don't run one anymore currently. Used to run a Mishimoto adapter and 10an fittings. But have found the earl fittings these coolers use as well as other oil fed components like superchargers use, all tend to weep for me at some point. Its annoying.

If a flare fitting is leaking when it’s been properly tightened, it’s a surface finish/interface issue. You can disassemble the fitting and verify that there aren’t any burrs on the interface surface, and even lap it if you’re feeling brave. Generally, especially with cheap AN fittings, the problem is a flare mismatch in concentricity or angle. There’s not much that can be done there. If the fitting is tight, it’s not going to leak any more than it already is.

I had a sandwich plate walk loose and almost cost the whole car on track. I won't run one anymore. I intended to cool the water going into the factory cooler by use of an extra radiator. Only reason I haven't done i yet is I haven't sat down and figured out which was in and which was out for the water into the factory cooler on the K series.

Never put Teflon tape on a flare fitting—the tape will creep and the fitting can lose torque and loosen.

these don’t always work for fixing bad flares but my personal experience they’ve worked well for me. I’ve gotten to point of placing these while doing initial install just to make sure it’s all good. AN fitting crush washers
