I've got mk2 rack and pump (red cap res), 1st stuff I put in it was green, but it leaks from every join, and now I top up with red?!(All I got in the shed) So its brown atm. Mine also whines like a bastard, as if its supercharged, is that defo the pas then- was told it was cambelt tension, then got thinkin it mite be water pump?? Also is that the tension then -5mm? Cos I've got more like 10mm and it does slip a bit when wet/parkin on full lock...
