https://www.shortwingpipers.org/forum/showthread.php?4795-Pipe-thread-to-AN-fitting-adapterthe fittings that go into each end of the oil cooler that the oil lines then thread onto... I noticed thread sealant on them, going into the oil cooler. I just flushed my cooler and one of these fittings was loose. I cleaned and re-installed the fitting. Should I have used thread sealant? If so, what kind?
Great job Steve, you must have spent hours putting this together. I'm enjoying all the little tips you recommend.
