90 Pickup, 4x4, 22re.

I want to do a valve job on my 22re, and set the timing, and idle.

Questions (Valve Job):

1. To do a valve job correctly, should the timing be set before the VJ?
2. According to the FSM the intake (cold) should be set to .000 is that a misprint or is it correct.
3. On the timing chain sprocket should the hole be at the top of the sprocket for TDC, and at 0 on the crank?
4. and you spin the crank clockwise (possible dumb question)

Questions (Idle)

1. I don't have a tach, should I go by a cheap tach?
2. I have a friend who has a 94 22re w/tach, can I "copy" his adjustment screw setting?

I know its pretty easy to do a valve job, I just want to make sure I do it correctly, going on an 800 mile trip this weekend.

Are you doing a valve job or setting the valve lash?

Mark Malone

Please enlighten me, what is the difference?

valve job is reseating the valve and you have to take the head completely apart and either lap them yourself or take them to a shop. It creates a good seal from the valve to the head.

setting valve lash can be done with the a feeler gauge, 30 minutes of your time and the valve cover off - a lot easier. lash is the space between the rocker arm and the valve stem. You set this so your valves can open and close with out getting burned up or screwed. sometimes you can see a noticeable difference after you do them if they havent been done in a while.

Please do not take offense to this but find a buddy with some wrenching experience, invite him over for a few beers and talk him into showing you these things........I base this on your questions which are followed by "I know a valve job is easy"..... yet then you ask what the difference between a valve job and setting valve lash..

Mr.Utah

I Agree with sportsmanphil .....learn how to tune it up right

Thanks for clearing it up! Yes a valve lash... job. Done it on several vehicles before, mostly Chevy's, always called it a valve job, must be a Cali thing!

Lash is no biggie. Get a service manual and it will guide you right through it. Minimal tools needed, the only 'special' tool needed would be a feeler gauge.

Now your valve lash in a chevy is completely different as they typically have hydro lifters and typically you bottom out the rocker or you turn the rocker down till the push rod has no play + 2 turns.

On your Yota you will need to set to TDC Compresson #1, adjust the intake and exhaust valves as per the service manual. Turn the crank 360 (180 at the cam) and set the remaining intake and exhaust valves.

Youtube it, plenty of videos on valve lash setting.

Do you turn the crank clockwise?

yes...

Mr.Utah

yes, stand facing the windshield and the motor, clockwise from this view.

Top dead center on #1 cylinder: take out #1 spark plug, crank motor until pressure is felt in the hole. Now you can bring the alignment mark on the harmonic balancer tto the top, your just trying to take all the pressure off the rocker arms so you can adjust your intake and exhaust. You may also want to check the tork on your head bolts. Use the fsm to determine the order of tightening and valve lash.
