Lastly to conclude a summer of interesting updates, I went on a camping trip this past weekend up to Letts Lake Campground in Mendocino NF with the roommates
that the truck would never finish. To listen to my harrowing tale, read on, dear reader...
To prep for the trip, I changed the front diff oil and transfer case oil with 80W-90, and did an engine oil change with 10W-40. The oil wasn't milky at all (but plenty black), mo that made me feel pretty good about the head gasket. But I thought it might have been down a quart or two of oil... my dipstick doesn't measure depth properly (the oil guide has snapped off inside the block), so it was hard to tell, just eyeballing it from how much it filled up the milk jugs. On the way back... well... looks like I destroyed my 2F. First time ever using my AAA membership, towed it back to Mudrak.
The truck had run pretty hot climbing through Mendocino NF the day before... almost entered the red per the temperature gauge (before kicking the heater on). Driving back from Mendocino, things seemed to be going just fine (other then the 100-degree Central Valley heat baking the GF and I).
But around Vacaville when we pulled over for lunch, it felt like that the truck might have been a bit down on power. It was really struggling to get moving in first gear (I had to floor it for it not to stall out), which it sometimes had experienced in cold starts in 100-degree heat but never after running for 2-3 minutes (figured it was some sort of carb gas flow thing). After eating, we got back on the highway in stop-and-go traffic, and I don't think the truck ever quite had the same amount of power again. It was just able to do 60, but not any more, and it really struggled with the grades going along I-80 into Vallejo, to the point where semis were passing and it wouldn't do more then 45.
As we entered Vallejo, the truck just felt like it was losing more and more power (and like it might have hiccuped once or twice). I pulled over after the 780 interchange (25 miles from Vacaville), where the engine died mid-turn on the offramp and wouldn't start again. Opening the hood, I found that the coolant overflow hose had come off the coolant overflow tank and dropped a bunch of coolant on the ground. Called the tow at that point to Mudrak because something was clearly very wrong.
My friends tailing me the whole time told me that for the 5-10 minutes before I pulled over, the truck had been shooting oil onto their windshield (???). And a few minutes after the oil spritzing started, then blue smoke started coming out of the tailpipe, then it switched to billowing white until the engine died on the offramp.
Mudrak was closed that Sunday, so showed up first thing next morning and talked to Gary. He said the compression was shot, he suspected it was the piston rings at a minimum, and that they wouldn't rebuild the engine but swap a new one in (and they have a huge backlog right now for that). I need to find a place to put the truck in storage by the end of the week, and then figure out what to do next.
I'm really not sure what I'm going to do next. From how long the engine had been down on power (losing cylinders?) and spewing things, I'm not even sure it's worth trying to do a rebuild (Mudrak/Gary definitely didn't think so). The obvious choice I think is to put in a new 2F (or sell), but I'm also considering maybe doing a diesel (like a 1HZ or 12HT) for extra power and fuel economy (and also put in a H55F while I'm at it, to make highway cruising easier). I would really like a 3F to move to fuel injection, but I don't think that's possible under our dear overlords CARB. Don't have a place to work on the truck, but I might be moving soon and have a chance. Open to any opinions and thoughts on what to do... first thing to find a place to store it where I can think and make plans.
I was not supposed to be back here so quickly... almost a month to the day from the last time.
