New engine runs!
The swap took a while (being my first time pulling an engine), but overall it wasn't too bad.
I was told the "new" used engine was out of an 01 4Runner with 165k. From everything I can tell this was out of an pre-00 manual 4Runner, based on the various lines and connections with it.
Overall the engine was pretty clean, and I was happy with my purchase.
Should have just done the front diff now, would have been so much easier:
While out and on the stand, I did the timing belt, water pump, all the various seals, and the valve cover gaskets. Incredibly easily to do when there's so much access!
I ran into some issues getting the trans mounted, no matter what I tried it felt that it kept getting stuck and the bolts simply wouldn't go in all the way. After fighting it for a while, I pulled the engine back out (not too hard, since the tranny was the first thing I was working on), and found a pilot bearing where the torque converter shaft goes in. This is when I found out that this was out of a manual. After a bit, the bearing was out, and the engine went back in.
Once everything was free, the trans mounted up very easily with no issues. A few hours of bolting everything back up and routing the various wires, and the engine was ready to start!
First crank made a loud BANG which made me very worried- did something fall into the engine?? After some quick troubleshooting, we found that somehow the EFI relay blew and that was the noise. I swapped the defog relay into the EFI spot (same relay), and tried to start it again.
After some struggling, it started! A bit of white smoke and then it was smooth.
Had a pretty major coolant leak from the oil cooler lines, so I swapped over the line from my old engine. I couldn't see any damage (maybe it just wasn't seated correctly), but it isn't leaking anymore.
Now I'm noticing a slow but steady oil leak from what appears to be the oil pan. My plan is to pull the engine again this weekend and reseal the pan with the Toyota FIPG and hope it fixes it. I'm also planning on inspecting the oil pump and surrounding seals while it's out to make sure it isn't one of them instead.
Regardless, it runs! I'm happy to have a running engine again. This one is smooth and quiet, and so far I've gotten 19-21mpg on the 3 tanks that have been through it. Not sure if that's just me being super easy on it or if this engine somehow gets better mileage, but I'll take it.
Now time to wheel it some more!
