I always put about 100 miles of easy driving then cahnge the oil. 300 more miles of easy driving then oil change. After that run it progressively harder. Running one like you stole it before the rings have seated is asking for trouble. IMO. My rings are just now seating on my fresh rebuild. It is the hardest thing I have ever done, driving a Mustang like a grandma in a lincoln.

sounds like someone didnt rtv the cylinder head bolts and lower intake bolts , and or the bolts were not properly torque sequenced, cold and warm.


you are not supercharged, that will not happen to a new headgasket that fast

^^^i was going to say the same thing....even driving the hell out of it right a way you should blow a head gasket (rings may not seal properly...). sounds like the torque sequence wasn't followed

I'd complain to whom ever the motor was ordered from, they should pay part of it.
