Isn't this like the 9th motor you've blown?

Thanks man, good to know...and what a bummer. Could be the same situation for the 2AZ, but I don't know.

How are you blowing this many motors, with no FI at that?

You can replace pistons & rods from the bottom, you don't have to pull the head, it's just easier if you do.

Thanks Toyota! (1NZ-FE from a 2004 Scion xB)

Can someone verify the 2AZ pistons will clear coming out the bottom?

FYI, one of our southern Maryland members had a similar issue, where he had crank walk and chewed into the journal. Saved himself a lot of trouble though rather than trying a repair he just bought a used long block and dropped it in after a compression check. Hasn't had an engine problem since. If you need to find one, use car part. Most salvage yards will ship and are pretty reasonable on price. Some even warranty the block for 30 days so you know you didn't get a dead one.

Good luck with the repair.

Piston cannot come out the bottom end of the block... do not attempt to rebuild the engine with the engine in the car. that is a crazy idea especially with out valve chain cover.

I would say pull it out and either take it to a professional for rebuild or pick up a longblock from a salvage yard. Cuz it seems to me that something is not right with the past two builds.
