Hello to all. I have been driving Toyota trucks for over 11 years now, and I have run a body shop for 19 years so I have some experience in the field. I recently purchased a 96 Tacoma 4X4 ext cab with the 3.4L. Like so many others it had bad head gaskets, and I think the previous owner let it get hot (probably many times), and probably cracked the heads. When I bought it there was water in the oil and it was chuggin' tons of white smoke. But the price was right so I limped it home. Well she locked up in my driveway so instead of rebuilding the heads I am just going to try to find a used engine. I know that the 3.4s are the same from 95 to 99, but the block is the same up to 04. My question is, what is the difference in the 2000 to 2004 engines? Are the heads completely different or is it just the electronics and maybe intake?
Thank you in advance for any answers!
