First thing you need to do is diagnosis problem. Which
cylinder blew the gasket. On the rear bank or front bank.
Is there water in the oil, how long was it their. The rear
head takes 3 times as long as the front head to change.
Many mechanic,s pull engine to do rear head. Some just
drop cradle at rear to make more room to pull rear head.
If water is in oil it may have damaged rod bearings.
Engine won,t last after you replace head gaskets. what
made engine overheat in first place. How many miles is
on vehicle? The rear head is usually beyond your
backyard mechanic. Possibly getting close to repairs
exceeding value of vehicle.
