Ok heres the scoop guys n gals...i have an 87 truck with the 22r, the motor has been to hell and back and wont last much longer if i were to guess. The #2 rod journal on the crank is toast and is knocking, and the #2 exhaust lobe on the cam is now completely round <img src="/forums/images/graemlins/drunk.gif" alt="" /> compression is good. Could the excessive wear on the crank and cam be connected in anyway???

I also have a 82 22r layin around with a good crank and cam.

I know there are differences between the 87 and 82 22r's so can i swap the crank and cam and throw new bearings into the 87 or would it be better to rebuild the 82 (even though i dont have the intake/ exhaust mans. and everything else) and drop it in the truck. This truck is my beater so my goal is to get it running decent within the near future.
Thanks.

>>>*Morning!

The early crankshaft is identical, note the rod beams are slightly different in the early set but they will bolt in in sets and work just fine.

If out of a running unit the weights won't be a concern that way, Toyota is very good at balance on these engines.....*EB

The rod beams??? bolt in in sets? Please explain.

How about the cams, are they interchangeable?

Thanks.

>>>*The beam of the rod is the section between one end and the other, the design is slightly different from early to later models.

Yes, use in sets. 4 from one engine is a set, the weights need to match. Or have them balanced.

Yes, all the cams interchange....*EB

hmm...swaping the rods adds a curve ball...i was hoping to do it with the engine still in the truck <img src="/forums/images/graemlins/drunk.gif" alt="" /> Are the pistons the same as well?
