Help!! Oil filter not releasing

[Denboy]

Garage tried to change oil filter and I was told housing is siezed on. They had it on the ramp and swinging with a long bar with the correct removal tool.

Any suggestions please?

I  sort of had  similar problem. There are lots of tools that look identical but there is only one correct tool. I posted a picture of it.

I had to use a 26inch breaker bar. anything short will not do. I had tried i think 14 inch breaker bar but no... 26inch or longer is what she wants.

Try spraying the housing near the gasket area with a freezer spray - eg Halfords 'Shock and Unlock' - I expect there's a garage trade equivalent. And/or a bit of gentle heat on the fixed part. And use a longer bar - but I suppose in the last resort the tool or the housing will fail (break). The base is integral with the sump - if the housing breaks, you would need to remove the sump for surgery. Could be expensive for what should be a simple task.

As jack says - a 26" bar should suffice - or add a piece of tube for extra leverage. The correct tightening torque is 18ft.lbs. !

This seems like a recurring problem with the is250, bad design?

Certainly very large diameter threads between Aluminium alloy components are a recipe for problems. All for the dubious sake of the environment really - saves a bit of 'tin' forming the canister etc of the throw away all in one type. Doesn't save anyone any money - maybe a few coppers in production, and throw away ones have worked fine for the last 30 -40 years or more.

It is absolutely crucial to get the torque setting correct - but how many mechanics use a torque wrench on oil filters?

none I would say.
