Hey guys.
Ok so I was reading online and I found out on a Chevellestuff.com that AN fittings are designed not to use any sealant because of their cone locking shape. By using a sealant, you can create leaks. Instead, they recommend using a lubricating oil. Has anyone heard about this before? If it's true, maybe that's why I leak a little oil from my oil pan fitting for my oil return line.

 

yes it is true

 

Yes, AN fittings seal on the mating surface, no sealant should be used..

 

ok next oil change i'm cleaning off the teflon. thanks guys. Do you suggest using oil or is that just above and beyond?

 

a very small dab of grease is cool, especially where they are next to a huge heat source.
