Just received my new oil filter adapter. It is a modification part for the MG TC, but it fits right on the Wolseley. This is just the thing I wanted: a sensible and strong solution!
Machined from a solid billet.
The thing is quite heavy at 1200 gr. and fits a spin on Mini oil filter. I fitted it within minutes. The engine builds up oil pressure as before, so it works fine I think!
