I was performing an oil change on my 02 TB today...As I was spinning off the oil filter, the double sized male thread adapter with hex head through hole did not remain secured to the oil filter base, it was firmly stuck to the filter...I could not remove it by hand, nor did I have the proper size hex head tool to remove it. Fortunately I was able to find a hex head bolt that was close in size, then double lock nut it to remove it. Has anyone ever encountered this issue?
Having been around engines for 50 years its a very rare issue at least from my experience. One would have to ask who strong armed that last filter in place? Most manufacturers say spin on 3/4 of a turn past gasket contact, I usually go a full turn past gasket touch, but have never had an adapter come out. You don't want to lock tite that adapter in because you are in the pressure system and you do not want any contamination to circulate or block passages.
Some filters may have a thicker gasket so even the following is a recommendation.
Verify the threads are in good condition for the adapter and where it screws in, no pulled or broken threads, and reinstall tight. Then install a new filter after lubricating the new gasket with a film of oil, tightening 3/4 to 1 turn past where the gasket touches the flange surface. My hands are weak being old, so I tighten with my
oil filter wrench because I can barely get a filter to 3/4, but always watch how far I have tightened it, even mark the filter at first gasket contact where you can see it and bring it around 1 more turn. They've always come back off, but it you go much further than 1 turn, watch out.
I remember one I did and the
oil filter wrench crushed the filter, I had to drive a screwdriver through it to rotate it off!! So tighter is not better!!
