I did an oil and filter change, among other things, for a member on Thursday.
It had the paper type filter fitted.
As soon as I looked at the cap, I saw it had been totally mullered, and thought "oh dear", or words to that effect.
I managed to get a tool on there, and started to slowly apply pressure - it eventually "went" and I thought great.
No such luck - would appear the cap was still tight, and the housing spinning on the block.

In the end, the housing was just wiggling around with oil dripping out the back of it. ACK - Can't currently re-tighten, and can't remove, without getting that cap off.
I tried all sorts, tried putting a strap around the housing and loosening the cap, no go. I tried holding the housing in some oil filter pliers while removing the cap = nope, just kept slipping.
In the end, I managed to get an oil filter chain to hold on the housing, and a special socket to hold on the cap. I was then able to remove the housing from the block, clean it up, and refit properly with a new filter - ensuring the cap was only at 15nm, not the 150 it probably was before!!!
Such ham fisted workmanship really annoys me, and took up a few extra hours of our time for me and the client.
It was a bit of an uncomfortable moment for a few minutes, whoever fitted it last wants shooting
