Finished my 2.7 swap over the holidays. I had some trouble getting it started, but was finally able to get it running this morning, and everything seems to be working OK.
Not that anyone should remember, but I lost the HG in my '98 2.7 4Runner back in November and ended up buying a used motor on eBay for a good price. At the time it seemed like a better option than rebuilding the top end of my original motor, as the original motor had 130k miles on it. In retrospect...I probably would have been better off just fixing what I had, because pulling this particular motor by myself was a big PITA. Anyway, the new motor is in and other than an intermittent knock sensor code, everything is working OK; I'm no longer driving a fog machine.
For anyone looking to pull one of these motors, I have a few suggestions:
1. Pull the complete intake manifold off first, and reassemble after the motor is back in the vehicle. I pulled the motor with the intake still attached and it was more difficult than it needed to be. Installing the intake with the motor in the vehicle isn't that hard.
2. Toyota uses two pins to help mate the block to the transmission bell housing. When you buy a used motor, it may come with one or two pins of its own. The rule is "one pin to a hole" -- make sure you don't try to put two pins in the same hole, as both won't fit. (Took over 1/2 an hour to figure that one out
3. The torque spec on the flywheel needs to be studied carefully. It's 19 ft. lbs. plus 90°
(in sequence). First time I've encountered that "plus 90°" requirement. Too bad I didn't see it until after we had the motor all back together.
Anyway, just a few thoughts I thought I'd share after completing this swap.
