Seized bolts on oil filter housing

[Pezone]

Hi guys has anybody else had problems removing the pipe hose bolts from the top of oil filter housing mount? one of mine is a bit rounded off and seems to have been done up by iron man. it really is seized on there, tried heating it but not too sure if I want to blowtorch so close to filter etc. Think a good old nut splitter will work? Cheers

Yes, had this a few times. Even when they crack off the nut siezes to the pipe too. Just have to keep going with heat and WD40/release oil over and over.

Its not a nut, its a male oil union so if you use a nut splitter it will ruin the pipe. Use some plusgas on it, and try to shock it with a decent fitting spanner, flare spanner prob best if you can find one the right size. Sometimes they just spin and twist the pipe, which is one of those things that happens to 30 year old parts sadly.

I like to heat then cool things like that, almost always frees them up.

Id be careful heating the sandwich plate as it has a rubber seal that goes onto the block on the rear, and its NLA as far as i know.
