Going to do an oil change on my new omega This has a cartridge filter my old omega had a canister. Is there anything I should watch for on this type of filter. The canister was a hand tight job is this a torque job

[tunnie]

only the lid to the canister should come off, but many moron mechanics over tighten it. (its only 15Nm)

24mm socket and hopefully just the lid will come off, just replace the paper filter and o-ring

[Grrrrrr]

There's a guide on here somewhere. Ideally you need a band-strap oil wrench to hold the cylinder part of the housing still while you unscrew the end cap. I had a b*gger of a job the first time I did it. Wait there a sec ...

[Grrrrrr]

Here you go: my tale of woe. Might help you?

 put reply in wrong place.  thanks for your help not looking forward to it The large O ring I assume goes under the cap . What seals the body  the bit that comes loose when you dont want it to. The old system was so easy why  change will probably use converter to change system

[tunnie]

paper filter clips into the lid, o-ring goes around the lid itself, and that makes the seal to the body.

Its an ok job, but much prefer the spin on canisters.

[Grrrrrr]

Hope your luck is better than mine.

Whenever I finally get a weekend off I get the car apart and then the heavens open. Just dumped all my tools in the boot and come in for a cuppa. Absolutely chucking it down out there!

Thanks Tunnie it was the seal between  the body of the filter and the engine block I wondered about Is there a flat seal there.

Thanks Tunnie it was the seal between  the body of the filter and the engine block I wondered about Is there a flat seal there.

There`s a flattened rubber seal (approx. 5 or 6 mm. wide) twixt the cartridge-casing and the block; rather like a spin-on filters rubber gasket, except the cartridge seal in bonded in the groove, it`s that seal that gives some people trouble if the lid is stubborn and the casing turns (relative to the block) when trying to unscrew the lid.

This happened to me and I had a serious oil leak as I couldn`t get at the casing securing nut.....I later decided to fit a GM conversion nipple (double-ended threaded tube) in the block which makes fitting of a spin-on filter possible (then I chucked the cartridge casing away).....the cartridge/casing shouldn`t give problems if the lid has been tightened to the correct torque and no-more.

The spin on conversion is worthwhile, as the spin-on`s are (generally) cheaper and a little more convenient.

Thanks Debs thought it  would be like that I will obtain conversion part just in case of problems

[Grrrrrr]

If a muppet like me can do it, anyone can do it. just make sure you have that metal strap filter wrrench and a 12mm allen key in case the casing comes loose. Once you these it is a piece of cake.
