Just moved over here from Off-Road, posted this there too, glad to see so many of the folks that helped me out over there are also over here. Getting ready to replace my timing chain, (85 22r) first time for me, (130,000 miles since it was done)and I have a bunch of questions. I am going to try and do it without removing head or oilpan, but may drop the pan if I find debris. Ok, last time I had it done, they installed a sleeve cause the shaft was grooved. Should i install a new sleeve? (Yes its leaking again) How hard is it to get the old one off? I have also seen mention in my searches to use the older seal (pre 85) cause it rides in a different place on the shaft or a newer seal (Toyota 90311-45014 front crank seal as used on 1994 22R/RE pickups) because it is thinner and rides in a different place. Anyone tried either of these tricks? Should I install a new tensioner as well while I am in there? Planning on a new water and oil pump too. Anything else I should replace (maybe the distributor O ring?) If I drop the pan, is it gasketed, or do I use some kind of Permatex? Thanks for any and all tips, i have found a bunch of sites with helpful hints, plan on doing this as soon as i get my garage cleaned out enough to get the truck inside.
