Well I pulled it down to a buddy's shop this morning, I can't really work on it at my mom's. One of those restricted retirement sub-division type places. I break the rules as it is doing fluid changes and stuff in her driveway. Besides, most of my specialized tools are up in Georgia at my place.
I was happy with how the truck pulled it. 87* day here and my temp never got above 185* (180* thermostat, Flex-a-Lite efan) and the tranny temp never got more than about 10* warmer than when I run in those temps pulling nothing. Had to pull a couple of pretty steep grades over two causeways.
Gonna see exactly what the problem is next week, but I'm 99% sure it dropped a valve and I'm finding quite a few guys on the Jeep sites with 4.7s with a dropped valve ONLY on cylinder #2 (which is the cylinder that took a sh*t on me). I'm the ONLY HO so far though AND I'd be the earliest at 102k miles. Next earliest one I can find did it at 144k miles.
A couple have gotten away with just a valve/valve seat/seal, etc. but some have had to have the head machined or have replaced the head. We shall soon see.
What kinda pisses me off is I got a neighbor with a '99 Laredo 4x2, regular 4.7 lives across the street and he doesn't believe in maintenance. 138k miles STILL original tranny fluid STILL original diff fluid. I'm **** about maintenance and mine blows up at 102k. His Jeep is lucky if he pulls into a Jiffy Lube at 10k miles for an oil change and always gets the cheapy $19.95 deal. I've run full synthetic in mine since the day I bought it and never go more than 5k between changes. I guess that's just how the cookie crumbles...
