22re compression stroke

Post by crackerhigher03 » Wed Oct 04, 2017 2:45 pm

I have a question for the Toyota guys. How do you find the compression stroke when installing a head on a 22re if the head was already off the engine?

The block has the #1 and #4 piston all the way up and the dimple on the crank sprocket is set at the 6 o'clock position


Dimple on the sprocket for the cam will be at the 12 o'clock postion

Is this correct?  I don't want to take a chance and bend any valves.

#1 and #4 at top of stroke, make sure the rocker arms have play on #1 cylinder.

Disty goes in pointed at #1

That should do it.

I had my wife hold her finger in the sparkplug hole while I rotated the crank with a ratchet... easy method and good for laughs.

That's a skinny finger! LOL
Mine won't stick her fingers in dark places anymore...kind of like most of you won't follow my most excellent trail navigational instructions :)

Hopefully the pistons were right before the head went on.

There should also be a "shiny" link of chain that line's up with that dot on the gear.

My main concern was installing a head and it being on the exhaust stroke and then to tear it back down again.
