Bit of a tipple with crankcase breather filter on a KAD32

[alt]

Went to change the crankcase breather filter on the KAD32 today....
Loosened it a bit with a filter wrench, all fine... but after a lot of spins I knew something was wrong

Basicly, the filter housing is assembled in 2 from what I can see, and this has broken (but not apart). Basicly, the filter is spinning on itself. The bit that screws onto the engine is solid, and the filter housing is spinning on it.

Space is tight (S23) at the back, so I can't get the filter wrench onto the bottom of the filter.

Has anyone any bright ideas?? I can get my fingers in to the back of the engine and touch the bottom part (the stuck part) of the filter but no way can I get enough leverage to spin it off, and can't get the filter wrench down there.

I haven't tried anything forceful yet.

I don't want to try heat to expand the filter housing as there's a lot of metal down there in a confined space (so a flame is out of the question) - The one thing I do know is that the filter housing sits on the outside of the screwey part on the engine, so expanding it would help.

Been there

From memory is this not a very thin walled tin canister with the two ends machine crimped on the filter body ,my way was to bash off body of filter and then use big screwdriver and hammer to tap remaining bit,collapse stuck thead a tad which then allowed it to be unscrewed with pliars and after with care by hand.
Did not want anything to drop into crankcase.

Simple, buy an oil filter wrench either the type with 3 legs on it that expand, or a fabric type with a half inch or 3/8 adapter, use socket extension and t bar or ratchet, have this a lot when they have been screwed on too tight.

I don't know what it is about those filters, they always seem to be tight to unscrew, as already mentioned if it really is that tight I use one of those rubber strap wrenchs. I think it is Duratool who make them, you see them as a twin pack, 2 sizes, the small one is most used for this job.
Of course it's not the easiest of places to get to on a S23, but you need to get the wrench down low onto the base of the filter at the lower joint where the filter body is joined onto the base that has the thread on, this should allow you to unscrew the filter - hopefully.

Thanks for the suggestions folks - first time this has happened to me with these filters... arghh!

Will update on what I finally end up doing (unless I just smash my head on the engine out of frustration!)

Put a bit of oil/grease on the thread of the new one - so it isn't stuck next year.
