Valve Adjustment Question

[Ray7Smith]

Just installed a rebuilt rocker on my BJ7. I need to know the best method of rotating the engine in order to adjust the valves.
Is using the starter motor to rotate the engine the best method?

Best method if yu can get a wrench or socket on the crank nut. Not always practical but it allows for the best control. Remove all the plugs to make it easy to rotate...

Remote Starter Switch Less than $20 at NAPA.

OR...

The original Starter Solenoid had a start button on the back of it! Replace yours with an original.

From there it's pretty easy, touch the button to get the valve in the correct position, adjust it and do the next valve.

I remove the plugs and put the car in gear and gently rock it(move it) to exactly where I want lifter on the camsahft and adjust it that way.

I still prefer to use the E O I C method of valve adjustment over the "13" adjustment.

Push your hand down on the fan belt to tighten. Rotate fan blade by hand. Works best in one direction only.

Don't laugh - I can't be the only one who has done it this way for years.

With the plugs removed, I use a 15/16 wrench on the generator nut in combination with pressing down on the fan belt. I have a fan shroud and so cannot move the fan by hand.

I also use a paper timing disc inserted on the distributor rotor shaft in place of the rotor:

This disc is divided into 60 degree pie slices and gives the proper order for adjusting the valves, starting with #1.

I use the fan belt method as well...however, its on a 1250 4 cyl... Am setting the tappets this week on the 2.6 and will see if I can do it the same way?

I'm with Patrick - plugs out, roll the car.

Watch valves, when one is down the partner is up - gap it and look out for others on the way at the same time, with little movement you can grab a few of 'em almost at the same time.

Carefull Bob. Use the EOIC formula to be sure the adjustment is correct o and never hit it exactly. Otherwise you'll be readjusting. The EOIC formula will make sure you're are the right spot on the camshaft everytime.

What is the EOIC formula? (sorry, haven't heard that term before)

 

[Dave Russell]

EOIC stands for exhaust open or opening/intake closed (adjust intake). There are several interpretations of just when/how much the exh valves should be open to do this. Some say exh. just starting to open, some exh fully open, some exh starting to close. I'll leave the when/how much to Patrick. It's usually done on long duration and or hydraulic lifter cams with long opening & closing ramps.

Here's the formula:

Adjust intake valve when exhaust just starts to open,

Adjust exhaust valve when intake is closing.(almost closed)

This formula was given to me by a machine shop in JAX Florida when I lived there and overhauled several Healey engines. He was a very experienced machinest and was able to repair any thing I threw at him with Healey engines.

I always just put it in gear and roll it, plugs out, 4th gear (don't know if anyone mentioned that) I have never had good luck trying to do it by flipping the starter on and off, but your mileage may vary.
