Hi there peeps ive bought myself a gtr, the first one ive owned, and i bought it with a knackered headgasket so im on with doing the job although im not a qualified mechanic i can use the spanners! Ive looked on our skyline forum for the info im after but no joy!! So thought id try here, what im wanting to know is how do i go about this? Is it easier with the engine in or out etc? And also info regarding the timing belt removal and replacement? Many thanks in advance
