hey OP - we seem to be living parallel lives in Ohio. I just bought an '05 SE V8 with 162k and two previous owners, both of whom did all service at the dealer (first in Nevada through 2017 and until 2020 in Ohio). My timing belt was replaced by the dealer at 89k in 2015 and not again since so I am also creeping up on the replacement interval.
I've used the Asin kit on my previous Sequoia (same 2UZ-FE motor) and it took me two half-days over the weekend but it was a stellar kit of OEM parts and the included instructions were very good. I'll probably use the same kit on this 4Runner sometime this summer.
I'm in Cincinnati and wouldn't recommend 2 of the 4 local dealerships that I've dealt with. There's one north of the city (Joseph) and one in Northern Kentucky (Kerry) that I haven't used.
Small world huh? As far as me doing the work...nah. I am 69 and over the years have done some things to engines but nothing more difficult than replacing a starter, changing plugs, drain and fill the vital fluids. I did watch a couple YouTube videos on the timing belt change on the 4.7L. The 3 part series by OTRAMM is absolutely the best.....but it convinced me I didn’t want to attempt it. The dealer (Byers Toyota) still has mine as like many things during Covid there is a back order coolant flex pipe that crumbled apart when they removed it. The Toyota Warehouse they ordered it from is out of stock BUT they located one in Boston Mass. at a dealer and they are overnighting it. Should be here tomorrow. They keep apologizing profusely and when they called today said they were taking 10% off the bill for my inconvenience. Tuesday they offered me a free rental. We have 3 vehicles so it wasnt necessary and I declined their offer. They also quoted me a great price on the TRD exhaust for my Tundra, about $200 less than another dealer.
