Anyone have this? I got the F106 without nipple and I have oil leak problems. Looks like its leaking from the gasket. Its not super tight but tight enough. How tight did you guys have yours?

 

I have had one of these on my car since the first oil change. I can't remember the part number right now, but I got the one with the nipple. You don't want to tighten it up too much because it's brass, but I've had no leak problems with mine. I just tightened it one with a wrench, good and snug.

 

I've had one on my car now for a year and it's never leaked. I tightened it down within reason but as stated above it's brass so I didn't go crazy with it.
