Toyota motor help (22r/22re)

[TLTCrawlin]

OKay my dad and I are rebuilding a 85 toyota 22r/22re, and he bought a head from a guy, that said it would work but its a 84 (little different).

We cant get the timing chain onto the cam, we're thinking the 84 head is a little taller, anyone know what the problem could be?

i will double check on that for ya. it's been awhile since i worked on those. i think the 84 has pop up pistons. different than the later 22r's.

Thanks, i found on toyota nation that the newer 22r (85+) has a smaller piston and taller head and block

I had a 22R head on a 22RE engine when I bought the truck (used) figured out that if you bust off a full link and replace it with a half-link, it will work fine.

Deck height, piston tops, compression, exhaust manifold to head bolt pattern, compression is different. I'd find the right head. 81-83 22R same, 84-88 (and maybe later) are basically the same.

He is gonna put this head for sell and buy the correct one.

84 was also the last year of the double row timing chain I think...

Thanks guys!

I did the same thing, except my block was an 85+ and I had my old head ported, polished, etc etc. I ended up swapping blocks since I already had the headwork done
