Very nice writeup. This will help alot of people.

Good write up, only had to adjust about 8-9 valves @ 170,000 on the engine

sde780

what are the specs I need to adjust them to for intake and exhaust?

on my civic they were two different specs, OP just has .006 as the only one

minilogoguy18

0.15-0.19mm (0.006-0.007in) Intake
0.17-0.21mm (0.007-0.008in) Exhaust

Read under tools required, near the top of page one.

Would doing a valve adjustment on my H22a4 cut back on some of the oil consumption @ 123k?

Very nice write up.
Im just confused, what exacly am I supposed to measure with the feeler guage?
And does it have to be an angles one?

BigBlock22

you are to measure the gap between the rocker pad and the base or heel of the camshaft (on dual over head cam engine). on single cam engines you measure the distance between the rocker arm tapet and the end of the valve where the retainer sits.... this is the actual clearance between the camshaft and valve. the feeler gauge does not have to be angled but it really makes it that much easier. using a straight feeler gauge may give a false sense of drag resistance for someone who is doing a valve lash adjustment for the first time.

BigBlock22

if you already have an oil consumption problem, no....most oil consumption is a direct cause from problems such as: worn valve seals/guides, faulty pcv valve, or degraded oil control rings. the thing is, if you do not do routine valve lash adjustment you may have valve train problems later on which can lead to oil getting past the valves. but it will not fix you current dilemma

BigBlock22

an old write up but good one to say the least even though some ghetto fabulous tools were used

mcnos

what happens if you turn the crank while you still have your spark plugs in

BigBlock22

the engine will blow up in a violent explosion.......... im joshing you. in all seriousness josh it will make it harder to turn over. dont turn it clockwise

serjey15

So I put the feeler under where the rocker taps and valve?
And then tighten it so its not wobbling?

BigBlock22

No, it goes under the camshaft (when the nose of the camshaft is facing up) and over/on the rocker pad. tighten what? the jam nut? the wobbling? are you speaking of the feeler gauge wobbling? not sure what your asking.........
I think its best that you do not do your valve lash or at least hope you do not do it just yet. It would be better if you watched someone do it first (have someone physically show you). You can google valve lash or type in valve lash in you tube and something will come up on video. The OP's thread was not bad but there are other valve lash tutorials out there that may be more in depth. If you read through this whole thread and still don't understand what is to be done, I dont believe I can explain it any easier without you screwing up your valve lash. It is something that you have to feel for yourself but also know what it feels like when done correctly. I'm sorry but perhaps you should pick up a automotive technology book or invest in a helms manual. Then have someone go over the actual process with you.

Just read this write-up for the first time. Excellent work.

nus_dogg

Yup, I love this DIY.

Nice write up.

h22acd5

great write up just finished my valve adjustment.

mikeschmeee

So is this only for H22A? Or can this be done on a H22A4 as well? I assume its exactly the same but I could be wrong since H22A was a bit of a different engine then the H22A4

that_boy_sammy

Its the same bro.

H2b-eghatch

so all the same specs even for aftermarket cams?

nus_dogg

Nope, not the same if you're running bigger cams. There should be a spec sheet that comes with the cams. They should recommend you to set the valve lash at a certain spec. I'm running Skunk2 cams and they want me to put them at .007" intake side and .008" exhaust side.

minilogoguy18

^That is stock, just on the looser end of stock.

H2b-eghatch

005 is intake low; .006 is intake high; .007 is exhaust low; .008 is exhaust high. recommend using .006 for intake, .007 to check, and .008 for exhaust with .009 to check
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^
so should i go .006 on intake and check to see if .007 fits if not then torque the nut down

.008 on exhaust and check with .009?

thats what we did and seems louder than before it was stock
also do understand that h22's have loud VT

running tuner 2 and S2 VT
