can sum1 tell me how to do a valve adjustment?? cuz my understanding is that you start at tdc with the #1 piston, rotate the crank 180 degrees then go 2 the #3 piston, then again 180 degrees go 2 the #4 piston, then another 180 degrees and go to the #2 piston, and after that go back in the same order to recheck 2 make sure none are loose?
does this sound right??
but ive also heard u can do that order n only turn the crank 90 degrees?

just 90°

 

i dont know. i keep hearing 180 degrees? but is this the right order as 2 how u do a valve adjustment?

 

The cam gear will only turn 90 degrees, but the crank pulley will turn 180. I explained the process in another thread just a few days ago. Here: https://honda-tech.com/forums/engine-management-tuning-124/need-help-valve-adjustment-2643128/

 

1,3,4,2 counterclockwise 90° turns

 

hm ohh ok thnks. 1 thing though i just read ur other post explaining how 2 do it and isnt tdc when the #1 piston is all the way up and the arrows on the cam gears are pointed straight up?

 

^ yes.
try www.c-speedracing.com for more info.
go to the how to section

 

That's correct.

 

oh ok but u wrote when u do the #4 piston its gna be at tdc but i thought when u do that piston the arrows are gna be pointed straight down??

 

TDC is just the position of the piston. Each cylinder's piston needs to be at TDC while you adjust that cylinders valves. Reason being that this is the position where both intake and exhaust valves will be fully closed.

 

ohh ok i got it. thanks a lot man. the reason i was confused was cuz i was hearing 90 degees and 180 all the time. but i didnt know when u turn the crank 180 the cam gears only turn 90 degrees so now it makes sense 2 me.

 

 

if you do not have vtec there are holes on top of the cam holders closest to the cam gears. they line up with holes in the cam shafts. you can stick a screw driver in each one and it will lock your cams at piston 1 TDC.

 

ohh ok. thnks 4 all the responses.

 

super , perfect pics for the job

 

You can also see that the cams will be off the rockers at TDC. That's the real reason for setting each cylinder at TDC. So if you can't figure out which one is at TDC for any given cam position, just look at the lobes and figure out which ones are off of the rockers.
