Pull your valve cover and check to see if you have a double row chain already. If you don't, the kit with the new timing chain cover and timing chain kit will run somewhere around 500.00, i think. Check out LCEngineering. They, and sevral other places including enginebuilder make metal guides. Some 84's came with double row chains and some came with single row chains.

^^x2. You might all ready have a double row. I did the conversion on my 22R-E and it was really easy...I used the LCEngineering kit and it was pretty sweet. If you don't get the kit, you'll have to source some parts(ie-timing cover and oil pump from a double row engine...etc). I do know that LCE's kit has a custom timing cover, now that could just be the shiny lazer etched logo on the front! The kit also had dual steel/rubber coated timing chain guides too and a lot of other stuff to go along with the conversion(check the site for full details). Basically, you should never have to mess with the timing chain again or worry about it breaking plastic guides.

1984 will not have a double roller. They stopped the double roller in 1980.

go to LCEngineering.com, they have all the answers you desire.

i took the valve cover off and it ended up having a single row chain knowing my luck so i guess i am going to get the conversion kit from Lcenginering for the 85 on up. so big blue you said the kit was easy to install and it has been working great along with the water pump and everything.

You could just go with the single chain kit with the steel guides and be good to go. Do some research and make a decision based on your needs. There's plenty of info 'round here to help out!

yeah, to be honest the only way id go dual row is if i was rebuilding my engine.. i'd go full out. But just to replace it, its not really needed. I'd go for engnbldr single chain guide set, comes with metal drivers side guide.. my .02

Its stronger, and as far a I remember it comes with two metal guides. Its not needed IMO, if you keep up on the condition of the guides or use a metal guide if you change your timing set.

You can convert it fairly easy as long as engine is manufactured before 8/84, per downey. I think after that they went to the slimmer timing cover.

Be cautious, my '84 4runner has a engine out of a celica of unknown origin. Never assume anything. Maybe theres a decoder for block serial numbers?

I did this on an '84 block that I swapped into my old p/u - you need the oil pump drive spline, the chain and guides from a 20R, and of course the crank and cam sprockets -- before you start though make sure you don't have the 22R "laser block" which doesn't have enough space behind the timing cover for a double row chain

Not only does the LAZRE block not have room for a double row chain behind the timing cover (and also uses a different water pump), but the chain has 96 links v. 98 links in the 84---> older blocks - the block deck height and cyl head heights are different.

To put things in a little bit of perspective:
For the cost of the LCE dual-row chain kit ($440+), you could buy seven of the single row chain with metal guide from engnbldr.com (~$60). If you follow the suggested replacement interval of 80K miles, that's 560,000 miles, and the dual row chain is likely to require replacement during that period at least once. More often than not, provided the engine is well maintained and not abused, the single row chain may go 150K+ miles before it stretches enough to break the guides so take that into consideration as well.
