I picked up a '04 4Runner Sport V6 (galactic gray metallic) last month after having my engine replaced in my '99 Isuzu Trooper 4WD with just over 56K miles.
Although I loved my Trooper and the dealer replaced the engine free, after doing some research on the web, there is apparently some design issues with the Trooper's 3.5L V6 that causes the #1 bearing to spin and trash the engine (I beleive it is something to do with not enough oil drains from around the pistons causing them to plug and use excessive oil). I had the oil changed every 3-5K miles and had all scheduled maintainence so it was definately not due to neglect. From the research I did, I don't think this is a common occurence, especially with so few miles, but I did not feel comfortable knowing the engine was replaced with the same type engine so I traded it in on the 4Runner. Truth be told, if Isuzu would have had a comparable vehicle to the 4Runner, I probably would have bought another Isuzu as they did take good care of me, but d***, is that 4Runner nice.
I've been lurking here for a couple months and this site has been a great resource so I just wanted to thank everyone for such a useful forum. I am now a Toyota convert.
