It seems that this is the best way to do it I have been told, I do not know if that is correct. The options are 1. Replace gear driven hex with longer hex from Audi with correctly centred parts 2. Power max option 3. Convert to 1.9 oil pump set up Now I have saved my penny's and I understand that a conversion can be done to the 1.9 oil pump on the basis that that was bullet proof I am considering that. However I am told ???? That they have to drill a hole in engine ????? So the question is this, hopefully for people in the know rather than those guessing, what have you had done to guard against failure and by who, who would you recommend.
