Our Z22SE has an oilcooler which a regular Z22SE from an astra or vectra does not have.
Normally no biggie, but we have run out of maintenance parts specifically for that.
Normally when you bought an oil filter kit for an NA VX, you would get a filter and an o-ring.
Here is a sample of the generic Z22SE filter that fits, but which comes with an o-ring that does not specifically fit our filter cap.
If the old oring is still fine, you can re-use it.
That is the easy oil filter change, where you can unscrew just the aluminum oil filter cap change the filter and be done. (put it back with 25nm)
Then there is the oil filter change from hell, where a previous owner or mechanic may have run into leaking issues, and used a lot of force on the cap (way more then 25nm) to tighten it.
When that happens, potentially the green o-ring seal can get damaged, and the 2 seals that are in between the oil cooler ring attached to the construction.
The 2 black rings you see here.
These black rings are no longer for sale with Vauxhall either, and you need aftermarket ones.
So best case scenario is a 5 pound oil filter.
Worst case scenario is also a new green o-ring, and 2 new black rings.
