Englishman Needs Help Urgently

[skyliner32gt]

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

If your going to change the timing belt, I recommend changing the tensioner and the idler pullys (and new tensioner spring), both cam seals and the crank oil seals, water pump.

If you are going to change it with the engine in, it will make getting the harmonic balancer easier to get off (they can be done up to 500nm), I recommend removing the radiator if your going to remove the harmonic balancer bolt with a extension bar against the chassis and quick cranks of the starter motor (700+ cca battery is handy) to free it.

I would probably leave this up to a qualified mechanic (even then I would only trust one that has worked on skylines before as I've seen qualified mechanics f**k up a timing belt change), the dangers of doing it wrong is all your valves smashing into the head.
