7M-GE headgasket
 

I just recently bought a supra mklll with 280 000 km's on it and the headgasket is still good the thing is is that i read up about the 7M-GE head gasket and how they changed it at the last second from asbestos to another composite. i was thinking it may have been changed and from the information i've gathered seems as though it hasn't. and was wondering at what knm's has everyone else's went?

its a factory error HG head bolts were torqued too low
my mk3 had just under 280'000 and it had a HG job just before i purchased it!!!
i havnt seen too many go to long without the hg going...

so whats preventing mine from going mabey it was replaced. but the owner devoriced her husband so she dosent know!
W/E dosent matter ill use arp head studs and 4 layer metal if it needs to be replaced
