How many miles on your Supra

Nah, the factory torque spec is WAY too low. Possible re-torqueing could do it IF done in wrong order but probably more likely overheating from a bhg or putting cold coolant in a hot motor would cause a crack?

Anyway, think mine's on 130k miles or so, engine rebuilt with all new bearings, pistons, rings & re-con head before I got it (p/o/ blew it up big time somehow, was bits of piston in car!), then h/g blew right away with factory specs & he abandoned it.

only around 3/4000 miles between when I replaced h/g and torqued up nicely & when the turbo let go ages ago. Finally got a brand new turbo on it's way as we speak
