Damn - lost compression in a cylinder :-(

Great to hear it seems to be sorted. It appears to be more common with cheaper filters, but I assume age can play a part. Had it happen on two of mine now as it happens. Both times a new filter cured it. I would imagine a few people have replaced far more expensive parts or have paid out money to garages etc to find a cure all for the sake of an oil filter!

Your assuming Tenacious used a Genuine filter?

I meant non-genuine.
