Dear Greg,

I certainly don't want to discourage you but after reading your
thread, some questions rose to me.
If the headgasket is leaking : why did it start leaking. I agree it could be leaking by "fatigue" but there could be numerous other reasons ( a warped head for instance, justifying a remachining ).
And what when it is NOT the gasket but a small crack in the head?
A new gasket will not cure that. You will have to start all over again! please untherstand that I am a 603 turbo owner with an overhauld (cylinder) head so I am very suspicious !
Last but not the least : I never heard of an aluminum head opened up and put back without being regrinded and not leaking afterwards!
I understand you don't expect much damage with that low mileage but it is this mileage that makes me wondering...?
Just one hell of advice : don't put yourself ( and your brother )
under pressure in advance by placing such a short " deadline"!
If you do mind that distance : why don't you preview some holiday at your brothers place ? Could be fun !
In anyway, whatever you decide : keep us informed about your findings and experiences !
Good luck !
Danny
