EFI fuse corroded? that sounds crazy!!But I won't count it out. I haven't found anything yet. Just received parts from 22reperformance.com and thursday headed to the machine shop to drop off my block and pistons. Yeah #2 cracked in a T shape and about a nickel size thickness hole. cracked all the way through and down the side to the piston pin!!! then #3 and #4 just a faint T shape crack on the top. I got my 4runner not running from a family friend with a blown head gasket for the second time so they called it quits time for a new vehicle 350k miles original owners. since i got it running, I have not known any other noise than what I thought was an old rocker arm motor clanking. This is my first toyota. Sucks that I have to spend money to put it back together to get it running to see what is causing the lean or whacky timing maybe. I will post when I find something. 22reperformance.com has been very helpful and taking time with my retarded questions considering they are so backed up and my engine had nothing to do with them and they are still willing to help. They just gained a customer.
