Looks like my white 86 Runner blew a head gasket. Dealer says the head may be cracked as well, but I don't think they have evidence of that, they're just guessing based on the overheating it was experiencing. Cylinder #4 failed the leakdown test, pointing towards a head gasket. Truck is still the strongest running 22RE I've driven.

So I gotta fix that or sell it. Recently rebuilt G54 trans, non-working aftermarket A/C, new 31" rear tires, worn 31" fronts. Bedliner in the back instead of carpet. Aftermarket rear seat. Some chrome SR5 bling that I've added to spruce it up. Rusted (about like Cory's around the fenders, worse down near the rockers). Lift blocks in the back to level it out. $1000. I can arrange to get it down to the area for free.

 

So is it still running like it used to?

I can vouch for the driveability of the truck, I've borrowed it a couple times when mines been out of commission and its always treated me right.

 

Yup, only clue that something is wrong was it started overheating. Further investigation found a little coolant in the oil and that the #4 cylinder leaked down pretty fast.

I think the problem is my dad has been driving it too slow for the past 2 years.
