Oil leak from filter housing

[Webby the Bear]

Evening chaps hope you're all well. Was doing my oil / filter today and noticed a larger than normal leak from the filter housing area (there's always been a slight leak). Cleaned it all off, dried it and after doing the oil change I just let it run on the ramp. Sure enough oil started to accumulate at the bottom of the housing where it meets the block. This is the housing for the paper element type.

I assume if I remove the housing there'll be a gasket that's perished? Any info on it would be great as I don't remember ever removing the housing. I assume it's just spin it off once the lid and filter is removed? Cheers boys

Ps it's a 2.5. V6 👍👍👍

Are you sure the leak isn't higher up and running  down?

It's been covered in the past
some people buy an insert and convert to a spin on filter
IIRC as long as the housing is not cracked then you can unscrew the retaining nipple and replace the seal

Thanks guys. No, 100% not higher up. I hosed it down with brake cleaner and dried it off with air. While car was running I had a little mirror checking above the filter, round the cooler lines etc and it was bone dry. All the oil was around the base of the housing.

Ok Dave so the spin on conversion is done for this issue? I didn't realise that; I assumed it was done cos some people preferred the canister and some preferred paper element.

Thanks for that I'll just convert it 👍👍👍👍

Typical symptom of repeated cap overtightening. Subsequent removal force will snap off the locating lug between the housing and block allowing it to rotate against the retaining bolt, loosening it enough to allow leakage.

You need a new housing and new seal or do the spin on conversion and never worry again

Cheers kids. I'll do the spin on conversion 👍

I suspect the spin on one is partly the cause of crank sensor failures.  Its certainly messier to change the oil.  I would strongly recommend keeping the superior later type.

I would disagree. Converted all my V6s and crank sensor failure was circa every 125k... Oil changes were every 10k.

Yeah, about 80-120k matches my data for crank sensor failure with spin-ons, not many genuine ones fall outside that.  Not sure if spread is due to how often oil is changed.

I suspect that it is a design life as that's the window that the suspension typically fails at along with thermostat and cam covers etc... And another reason why the Omega has a reputation for unreliability and repair cost post 100k  miles

Mine definitely failed within that range .. original canister filter.

Ok kids. The man from Vauxhall's no longer sells the screw in fitting thingy. Anyone got a spare they could sell to the bear 🐻

Let me just have a look.




No.





Sorry.

To be fair mate I wouldn't expect you to have. Invalid carriages don't utilise oil filters. 😃😃😃👍👍👍
