I have a 2002 LQ9 engine that used a UPF44 oil filter. I swapped the deep truck pan for the 98-02 camaro pan. When I went to install the oil filter, the threads on the camaro pan are a larger diameter. I thought all of the LS engines used the same filter. Has anyone seen this on the pans from GM? I ordered the parts from an out of state dealer. I looked at rockauto and they list a pf46 filter for both 02 escalade and 02 camaro.

Having same problem. None of the LS1 oil filters are fitting on my F Body pan.

After going to the dealer, I was told that the new 98-02 pans from GM are sold with the boss to use the pf48 filters that come on the 07 engines. It looks like the filters have an anti-drainback valve in them. I was also told that I could switch the bosses out from my truck pan so I can use the upf44 filters I already have. I am trying to find out if they make an ultragaurd gold version of the new pf48 filter.

All NEW GM pans have the PF48 filter boss.

Hate to bump an old thread, but I am having the same issue. I bought a new LS1 oil pan for my new shortblock and I bought the wix extended oil filter pn51522 for a little more oil capacity and is what I used on my old motor and it will not thread on the new pan. Any info out there on what I can/ should use? I'd like to stick with wix oil filter

Casting p/n on pan is 12558899 and GM p/n 12628771

Looks like you may have answered my question. I'm guessing this pan has the new oil filter boss then... Looks like I'll be returning this oil filter
