Yes, I bet this will give all the professional builders a laugh. but I can't for the life of me remember if there was anything in this hole between the cam follwers? It's not threaded, still some road dirt in it by the looks and I don't appear to have anything that fits! Loosing the crank dowels has knocked my the confidence out of my store approach. I found a picture in the Bently manual that shows something but doesn't list it! As I've been told on here - VW didn't do something for nothing Help, derision and comments please.....
