So first oil leak was attributed to a faulty oil filter. The second one was also because of the oil filter. Hopefully this one won't leak. I received two faulty filters in a row, what are the chances of that?!

This problem has been documented in Motorcycle Magazine (UK) Their oil filter had bad threads and had the same problem as mine.

So please make sure you check the oil filter carefully when doing oil changes.

Here in the UK oil filters are available with both metric and UNF/C thread and if of the same approximate diameter the threads are very similar, a slight slackness screwing UNF/C to a metric holder being the only clue; a metric filter onto an UNF/C will be obviously too tight. Some UK specification cars, eg Volvo 360, can have either depending on year and one must gauge the filter holder thread before ordering a replacement filter cannister.
