Maybe I could try something different. Does anyone have a link for a pdf manual on the 4555/56? I have a shop manual for the truck, but it doesn't cover the engine.

On a side note. I do not plan up doing any performance upgrades or trying to max the output of the little diesel. This truck is strictly going to be used for a commute to my pasture to check on cows and do some light duty hauling, etc.... I just want to maximize the life and MPG of the truck.

Thanks!
Is the push button factory? I have a button on 11v plugs so i have to hold it around 10 seconds when its really cold. If those are 6v then they hold 12v for a few seconds before dropping to 6 for a fast warm up.

Watch this, this was when i had atleast one weak plug

Regarding head, not really, tend to crack between the valves, so you will slowly burn coolant and pressurize the coolant system.

Also, since you already got the truck, what state was it in?
