Gti brake servo pump - Niall - 28-03-2013
Well thanks to Ruan suggesting it, I think I've finally located the source of my oil leak which is where the servo pump bolts to the head. As I understand it, this is driven by the exhaust cam correct? Is there a seal between the two faces or is the oil seal actually around the end of the cam? If the latter, can I replace it without removing the cam?

Yeah, whip it off and you will see a rubber 'O' ring...
could try removing and resealing with some automotive sealant? or try and source a new one

Yeah want to get it fixed this weekend. This may sound a stupid question but if there is no seal at the end of the camshaft, im assuming the pump is supposed to be lubricated by the engine oil?

thats correct.

Removed it today and looks like it has been sealed before but not very well! cleaned it all up, packed it with RTV and bolted it back on so time will tell if its alright!
