Now's the time
Yeah, now is the time to do the valves, cause when you've got the plugs out (all 3 at once) you can easily turn the engine by hand using the accessorie belt pulley, where you need to, as you go thru the valve adjustment. HEY, but when you have all 3 plugs out, put some paper towel or clean rags or whatever into the plug holes. Just in case you drop a small bolt :!: Fishing it out from under a rocker arm would be bad enough. Out of a cylinder, Hooboy
A short, straight length of rubber hose, of a size that will go over the plug porcelain, will make getting them back in without cross threading a snap. Just poke the plug into the hose, then use the hose as a 'handle' for threading in the plug. When your plug is nicely screwed all the way in, just pull off the hose. Torque on the plugs is another crucial step also.
The valve part:
The intake side goes at .009" the exhaust at .010", stone cold engine. Nice to work on, all cool an comfy on the hands. Follow the torque specs on the adjuster lock nuts, don't wanna have 'em come loose. It was easy, just need a decent length 10mm box end ( the nuts are really snug on the adjuster screws) and a straight blade screwdriver and a feeler guage. It takes a very
light touch on the screwdriver or you get the adjuster screw too tight, but just play with it until you have a firm (judgement call here) pull on the feeler guage, then duplicate that thru the rest of the valves. Double check the feeler guage after you torque the nut back. Unless you have a manual to tell you, look for the cam lobes to be opposite each other, and 'horizontal' for the cylinder valves you're doing at the first postiion mark on the camshaft sprocket. The intake lobe to the front of the car, the exhausts to the back. The order that you do them, (i.e. 2,3,1 cylinder) is not important, as long as they're all done. Mine started off with #2 available first, so I started there.
If I was working on these for a living, I'd have to get a super light torque wrench, cause some of these bolts, etc. are WAY lightly torqued compared to other cars.
After you're done, what a smooth idle you'll have. Nice! 8)
