Happened yesterday, HG gave out. 1996 with 226,000 on the clock. Guessing it also had some hydrolock going on, as the truck would not turn over.
The radiator is empty, and smells of gas and exhaust. The dipstick shows the oil pan is full of milky oil. After a bit of MUD research, HG is the culprit. Looking into the alternatives, fix it, replace with another 1FZ, or V8 swap. Since I am not inclined (time and skill and space) to perform the work, I think the V8 swap is out of consideration.
Have emailed my mechanic (I trust him), and will hear from him tomorrow. Good news is this is a spare vehicle, so will not be under a rush to complete the job in a quick time frame.
One thing I think is odd, when I started the truck - prior to the diagnosis of HG failure - the engine jumped and popped loudly, kind of like it was overcoming an obstacle, and then threw a belt. I immediately looked under the hood, and saw nothing out of sorts - HG was not in my mind. The second start it sputtered. Third time it caught, and stuttered then smoothed out. Steam poured out of the exhaust. Drove it down the street, then brought it home. It won't crank now. Tried it one last time after diagnosing the HG failure, and the engine won't turn over. Have not tried to manually turn it over, kind of afraid of inflicting more damage.
OK, here is the Tech question, how much damage have I done? Reading that running with a blown HG can cause rod and bearing damage, but not always, has me scared. I am afraid the loud pop and the violent force that surged through the truck was the death of the truck. Any experience with explosive HG failures?
Thanks.
