how big a job

[daytona]

to replace the timing chain, i hear a rattle around 2000 rpm's and from what i have read on here, it sounds like the truck is due. its a 86 extra cab 4x4 with 22re and 166000.

is there an online guide? i tried to search it out on here but couldnt find anything.

does it take long? or any shortcuts?

It's not that bad of a job but, if you go by the factory service manual they tell you to remove the head to get the timing cover off:eek: . You DON'T have to do that, just drop the oil pan, remove the oil pump and the cover will come down enough so you can remove it without damaging the gasket between it and the head. Other than that, just follow the service manual steps. And don't forget to remove the bolt that's under the distributor gear, it's easy to miss!.........Hans

yeah its really easy, like he said though, dont pull off the head unless you want/need to replace the head gasket too, just make sure you drain ALL the water out of the block and drop the oil pan, and from there its a no-brainer, good luck. oh, and make sure when you put your oil pump back on to pack it full of white lube and prime it before you fire up the engine, also torque the bolts to the right spec, when i did mine the last genious who had worked on it over tightend them and cracked the timing cover.

When I did my timing chain I took a large piece of cardboard and sketched the outline of the timing chain cover and other parts on it. Then, whenever I took a bolt out I would punch it through the cardboard and make a note. This way I always knew which bolts went where.:yes:

I do the same thing, makes reassembly a heck of a lot easier:)

Just make sure you get the marks on the gears and chain lined up properly.
