Re: V8 Miss-behaving....
So a quick update...
My Jeep guy took a look at the problem, it turns out not to be electrical at all, but the 'valves not seating correctly' problem..
Took both heads of, and it seems like the valves on cylinder #2 smacked the top of the piston pretty bad aswell, so far $3300 in the hole to have it all repaired.
So work being done:
New waterpump - suspected of not operating correctly, warn imppeller blades
Heads to be rebuildt - Engineering work
New head gaskets
Removal of sump to pull out piston - New piston and rings, no damage to cylinder sleeve (luckily)
Replacement sump gaskets etc.
Starting to wonder if its all worth it as I paid around $7000 for the Jeep.
