Well got a nice little tent shop built up and tucked my yota in it..only took 3 years of it sitting around the yard.. Its seems the engine is seized and it leaked alot of oil when it went... Timing chain is still intact so I'm gonna guess crank rod? Anywho got everything unbolted and the engine is getting plucked tonight. I have a few other pre85 blocks I'm going to see if I can get a build out of..

So the guys at work started convincing me to try a propane setup.. Anybody try this before on a 22r?
We got to thinking its not much different then the setup for a forklift..
Gonna try an impco ca100 mixer attached to Toyota throttle body and a impco j regulator... Whats your opinions???? Did i mention I got the propane components free... :)

talk to crimsen on here, he has a 22r turbo'd on propane in his truck. He can probably help you out

Well the engine is out and all torn down to the block.. Everything looked great besides the little prices of bearing I found in the sump.. Engine is still seized but the piston walls still look great.. So who has any advice for me before I start tearing apart the crank and rod caps...? I've never gone this deep in an engine before and some help would be great..

mark the caps and rods so you dont mix them up
if you have a number stamp set use that or a center punch
start at timing chain front of motor
and work back

The hanes manual talks about measuring the gaps between the caps and the thrust bearing.. If its seized and prob needs a grind anyhow can skip this step..?

use toyota bearings seem to be a better material
and lets face it they go 400000 k plus
on the original ones
if the crank is chewed up you might be better to get another motor
to rebuild
not shure about toyota cranks and turning them
the early datsun ones were hard cromed on the journals
so if you had them turned you had to get then recromed

turns out #4 melted burned up a bearing... and #3 was on its way... all of the bearings were looking worn out.. doesnt seem to of hurt the crank just gotta remove the bearing thats melted lol.... so is it better to get it grinded down a hair and can they fix the conecting rod... from what ive read around on google is the rod has some fairly small tolerances.. but also what im seeming to read is that the crank and rods are interchangable out of any year 22r/re.... just the piston is different. geuss ill find out lol...

Most Machine shops will POLISH a crank first, to see if its worth grinding, or its good to go with .oo2 or .003 oversize brgs.

Turns out its grindable but I will need a new connecting rod... :s good thing for those 2 spare older 22r's I picked up :) according to mechine shop any of the 22r's had the same connecting rods and crank.. 85 they changed the block and head around and then the new info he told me was that the 22re had more differences then I though I guess it has a whole different block height and crank??? Who knew lol... So the tear down of engine 2 is well on its way p.s. moving an engine with a wheel barrow proves to be risky lol darn tractor ran out of fuel.... But I managed to get it on a stand with a little maguivering .... Anyone know what emmisons crap I can leave off? I noticed this engine has a cover on the back of the head where that pipe crap is... What about that extra pipe off the header can I just make some plates to cover the holes????

So another question.. Go with the older 80-81 22r with the dual timing chain or go with the newer 85+ 22r with I believe more power???
