took this pic from another thread, do i put the feeler gauge under the middle cam lobe?

 

nope just the primary (non-vtec) lobes


edit: sorry for the early morning brain lapse. what WILL come in handy are feeler gauges that are slightly angled/bent so that you can get down between the lobe and the rocker arm

i thought i put the feeler gauge right there? thats how all the pictures showed, you mean put the gauge where you nut and adjusting screw is?

u've confused me now, what am i gauging here? is it in that picture?

 

yep, you dont put it under the vtec lobe, unless you want to go chitty chitty boom boom ...

its apparent when you go to do the valve adjustment.

 

*confused* is it asking to much for u to put an arrow? ;/ i thought i had this all figured out from reading on here and c-speedracing

 

edit: check the pics from cspeed below

oh ok, it is early for me too, comprehension before 12pm isn't my strong point

 

to john wayne for takin the time to explain it

 

taken from c-speed racing...





you adjust and measure from opposite sides of the cam

*** the important part is to make sure that you do each cylinder at its TDC position

 

i completely missed that 2nd picture, only saw the first.

i know that it says to turn it counter clockwise 90 degrees and go in firing order 1-3-4-2, are there any marks so i know when its exactly at 90 degrees?

the cam gears will be marked in 90 degree increments so when the marks are lined up in the center (face to face) you will have a cylinder at TDC. visually inspect the cam lobes to verify that you are on the correct cylinder. the lobes should be facing AWAY from the rocker arms (b/c there is ZERO lift on the valves at TDC)

 

ok did cylinder 1, ex and in went fine, rotated it 90 degrees counter-clockwise to TDC marks lined up again on the cam gears, went to cylinder 3, (third cylinder from driver side) and i tested the feeler gauge before even adjusting it and it doens't go in it at all, did i tdo that correctly, seems like it should go in somewhat (this is the exhaust side that i tested)

 

IF everything is lined up properly from TDC and the feeler gauge doesnt go in it means that it is too tight and you need to lower the rocker arm.

valves DO go out of adjustment so it could possibly be that its just a little bit farther out of spec than the others. is there any abnormal wear on the cam lobes?

 

lemme go check, i'll take a pic if i'm still unsure....

 

well thanks for your help, just finished it. i actually roated it 180 degrees until those little marks touched eachother i thought there were 4 of them on each cam gear not only 2, so i went a whole another revolution till it was in tdc for #3 and then the lobes weren't touching the rocker arms

thanks again for your help

 

please enlighten me... why should you measure the valve clearance using the non vtec lobes? i looked in the helms and it didnt specify which lobe to use

because the Vtec lobes are not locked when the car is turned off

 

man I hope you did it right. it takes some practice but this is definitely not something you want to F up. just make sure each cylinder is at TDC when you do that particular cylinder's valves. and dont make the tolerances too tight or the car will feel sluggish.

 

And don't angle or bend the feeler too much or you'll get a fugged up reading.

 

Engine should be stone cold when you adjust the valves too... do it in the morning before driving the car.

 

I heard the toda distributor do it at this way


Don't know which way is right!!

simple. follow the helms, and put the feeler guage between both the primary/seconday lobes and the rockers. on a dohc b series, DO NOT put the feeler between the valve stem and lash adjuster. besides, being a pain in the ***, you risk not getting the adjustment right. i have done umteen billion of these, and it is a very simple procedure, although if done ham fisted you will wreck your motor.

This way does not take into account the rocker ratio so if you do it this way with the same specs. it's gonna be too loose at the rocker/cam interface.
