Death of a 4.0

Took the head off the Jeep tonight and realized I just got http://i118.photobucket.com/albums/o..._dlp/bruce.gif

Ouch. That's still a might nicer than the Jeep Cherokee that rolled over in front of me on University this afternoon.

Yeah, I'll take a motor issue over a roll any day. It's going to get stroked to 4.6 since I will have it out.

*wads up gun wish list and throws in trash*

I have to ask how the hell did you do that? I have blown a few motors and seen NOS melt things so enquiring minds want to know. :?:

Driving home from Florissant at midnight and it was 10 below. It started to get hot so I pulled over and shut it off. Let it cool down for a bit and fired it back up and temp was normal again. Drove like mad to get to Divide so I wasn't stranded in the middle of nowhere. Never got hot again but it started pinging right as I came into town and then died. Checked the coolant and it was full but it seemed really hot. Never ran again so I hiched a ride to Woodland Park in a snow plow. I could tell the head gasket was blown so I got a new one and took it apart and there you have it. I think the thermostat froze or something because there wasnt a drop of coolant in the head.

did ya lose a freeze plug?

No, they're all there.

hmmm.. not much in that system.

thermostat
freeze plugs

blockage?

any coolant in the engine oil?

Freakin' thermostats. It's those $5 parts that get you in the end.

your radiator was frozen.
Happens a lot in real cold temperatrues
The motor starts, it gets all warm, but it can't get into the radiator because it's still frozen and nothing heats it up
then you burn it all off as you blow the head gasket.

You'll have to mill the head and deck, for sure they are warped.
