Oil filter bolt

(1/3) > >>

Athame57:
Is there actually a torque setting for the oil filter bolt? I know it shouldn't be tightened as much as other bolts, but I always seem to get a mess start to develop over time between the housing and the lower part of the crankcase ...too loose?  ::)

taysidedragon:
I just do it up gently, a bit more than hand tight and never have a problem.  Make sure the joint faces are spotlessly clean and always use a new oring.

Bryanj:
There is anecdotal evidence in US that some pattern oil filter O rings are smaller in cross section so tend to leak

That might be the answer Bryan, as I've tended to do like Tay said. The new oil filter I have here is HIFLO FILTRO HF401. I've been using these a while now. Looks good, I hope it is.

exvalvesetdabbler:
I have used the hiflo filters for the last 3 years and no leaks. Just tighten the bolt until you feel the oring is being compressed and you then feel the housing bottom out on  the engine then nip it up a little, probably <1/8 turn.  I would guess 6 ft/lb at the most.

The OEM bolt that had a small hex was prone to rounding off when folk overtightened them.

For me, 6ft/lb is a short ring spanner, thumb on the nut and two fingers  half way along the
spanner.
