Timing belt replacement
Most of my early service was done by my local Toyota dealer. As luck would have it, my neighbor 2 houses over was the service manager at the dealership. We were friends before I bought the truck, and it's a long story but he would drive my truck to work, have it serviced (at the good neighbor discounted rate :ylsmoke

, call me for a CC# for payment, and drive it home that evening. He did the same for my (now ex-) wife's Camry. He was just the nicest guy. He and his wife ended up moving to Austin, TX a few years ago to be near their son who is a musician, so no more bro deals on service. I do most things myself now anyway, except for timing belts and such. I could probably do that too, but i'd rather pay a pro than spend all day tearing my truck apart.
The first TB was done at 90k, right on schedule. The second one was done at 185k by a small, local independent shop that my (new) wife has used for years and recommended highly. I am very protective of my rig, so I did a lot of research on this little shop. They had hundreds of great reviews on the interweb, and when I talked to them on the phone I got a good vibe. I checked into my local dealership also, only to discover that their service department has really gone downhill... hundreds of awful reviews. I ended up going with the little shop. I really like to support hard-working local folks whenever I can. I also had them replace the water pump and the cam and crank seals while they had everything apart.
I dropped my truck off in the morning, stole my wife's car to get home since she works a few blocks away from the shop. She picked up the truck and drove it home that evening. Sweet! Well.... the next morning when I started the truck, I knew something wasn't right. The idle was not silky smooth like before. I wondered if I was crazy. Later that day, my wife and I took the truck to go to the movies, and I tried to accelerate around a slow car on the freeway. NO POWER. Crappy mileage too. I run a ScanGauge, and normally get 15+mpg. I was getting 12.5 now. I immediately called the shop, and the service manager said bring it in first thing in the morning. He never balked, just took my word that the truck wasn't right.
The next day they tore it all back apart and found the timing belt was off by one tooth on the crank. Oops. Sincere apologies were made, and I picked the truck up that evening. On the drive home I could tell it still wasn't right. That's one advantage of owning a truck since it was new. I called the manager again, and again he didn't balk, just took my word for it. It's hard to get upset at a really nice guy that doesn't try to argue with you. He said bring it back in the morning.
I dropped it off again in the morning. They definitely got faster at teardown/rebuild! The manager called me at 2pm and promised me it was done and done right this time. He explained that his mechanic had used the "cheat sheet" that came with the timing belt kit to line up all the marks, but there was a problem. On the left cam there is a "T" stamped into the cam pulley, and he was using that as the timing mark. Two teeth over, there is a very small "l" mark, which is the correct timing mark. The mechanic had to drive to the Toyota dealership and actually borrow their service manual to figure it out! The service manager, whose name rhymes with Don, was super apologetic, and he knocked off $400 off the bill I had already paid. Now, I know some of you readers are thinking this crew is a bunch of hacks. I had a difficult time keeping my cool too, but in the end I am glad I did. The truck runs perfectly smooth now, gets better mileage, and it only cost me 600 bucks including parts, albeit 3 days of my time as well. Also, it turns out that Don is a close friend of my wife's boss, which she never knew before. He's actually a really good dude. Anyway, long story, i know, but if you ever have a problem with a timing belt job, you'll know to look for this mistake.
So now that that's over with for another 90k, on to better things, like armor...
