B series valve adjustments

[Spoon-Accord]

Hey guys!

Wanted to know, if the valve are adjusted incorrectly (eg too loose) would that cause hard cold starting and sluggish performance?

I think is the culprit but I'm not too entirely sure, I went and bought a blueprint valve adjuster tool( a 10mm socket thing with handle and flat head screw driver thru the middle)

Any advice/help would be appreciated

Too loose - valve not opening all the way

Justget feeler gauge and check

[mocchi]

so waht did you do with the tool you bought
did you try adjust with it?

[Spoon-Accord]

no no

i did the valve adjustment without the tool (so i think adjustments moved when tightening the lock screw or i just completely screwed up)

car runs, just noisy now and i get bad cold starts and laggy from 1k-3k rpm :(

Maybe a new fuel filter? It rectified my cold startup issues. :D

i've already replaced the fuel filter

car was fine before i touched the valve adjustments, so i betcha it is the valve adjustments

also, has anyone ever attempted on DIY the LMA.s?(lost motion assembly)

[sebtoombs]

Yeah I did it on my D15, worked great. Was a really old engine so the adjustment reduced valve slap somewhat, and restored a marginal amount of power (based on the "butt-dyno"). I haven't done it on my B16 yet, however it looks to be exactly the same except that you require angled feeler gauges because everything is a bit further down.

The procedure must be done with the engine cold.

Rotate the engine so that the piston in cylinder 1 is at TDC. Check clearance with feeler guage. Adjust if necessary. Re-check and repeat adjustment if necessary. Then move on to the other cylinders. (Each check/adjustment must be carried out with the respective piston at TDC).

The hardest part for me was forgetting to make sure each piston was at TDC, so I did the whole procedure twice through to double check.

Thanks for the reply guys
Well I'm just waiting of my valve adjustment tool I bought to make it more precise and accurate, I know I buggered it up!

But I've purchased a turbo kit and hope to put it in next few weeks yayy

[zhong]

If you got noise after you did your tappets - most likely means you did it wrong (probably got the TDC wrong etc etc).. I'd refrain from thrashing it man, cause bad things can happen if they're not adjusted correctly.

Definately get it sorted before you turbo it, goodluck!

Peace.

Hey bro,

Yes if they're too loose the car will start poorly and be very weak around 1,000-4,000. Really needs to be done properly with a feeler gauge. Just need to hold the screw driver still/tight while you tighten the nut and re-check once they're tightened to make sure they haven't shifted.

[cbauto]

pm me if you need mechanical service

[Spoon-Accord]

Thanks for the reply guys, just received my valve adjuswnt tool from the states ( what Honda use to adjust the valve lash) makes it an easier job, instead of having 2 pieces of tools and fiddling with them and trying to get the valve clearance perfect, this one piece tool does it with no effort)

Ill be doing it this afternoon when I get home, left my car home today so it'll be cold cold before I tackle the valve lashing

post a picture of it....





























































please

[Spoon-Accord]

hey guys

i'm tackling it again!

do i insert the gauge from the bottom or from behind (spark plug hole side)

cause if i put feeler gauge thru front it's different from behind (from spark plug side set, when inserting the feeler gauge thru front, it's all loose)

dillemaaaaaaaaaaaaaaa

[dougie_504]

Plug side, opposite to adjustment side

[Spoon-Accord]

thanks andy!

well i did do that

and when i put the feeler gauge on the adjustment side, it's all lose

alot of DIY articles show both sides, not sure which one to believe now

btw i'm using angled feeler gauges too.. this has got me stumped....

[mocchi]

what spark plug hole side? what adjustment side?
what are you talking about

[stndrd]

You want to put the feeler gauge between the rocker arm and camshaft from the center of the head towards the outside

[dorikin]

correct, as per service manual it should go in from centre and come out outwards

[Spoon-Accord]

ahh okay, thats what i was trying to to say, sorry about the choppy words.

would it make much difference doing it from outside inwards?

because when i did it from inside outwards, set the valves, then stick the feeler gauge from outside in, it becomes loose (or should i just go with the inside out measurement and forget the outside in measurement all together?)

[rossirider]

Check this vid out. He actually has a lot of vids on Hondas http://youtu.be/-G_Nq2orpfo

[cbauto]

would it make much difference doing it from outside inwards?

yes..

[Spoon-Accord]

thank you so much for the replies, think i'll get someone to do this.

[VT3C]

i cant think how i did them inside to out or not but I know it's only 'easy' poking them in from the one side. always double check after tighteneing before you adjsut TDC for the next cyllinder. I bought one of those tools over a year ago but havnt even used it yet, i used to just use the good ol bent spanner ;)

I always make the feeler gauges a tight fit too.. never had any trouble.

[Spoon-Accord]

i think thats the problemo, i'm not sure how tight or how much drag it needs to be. i've done it 5 times, either rough idle or just tappy tappy (it's loud atm)

[dougie_504]

Like a firm grip kinda, goes in out and relatively easy but bites and skips/jerks a bit when you slide it.

Lol :D

[VT3C]

exactly :)

AND ALWAYS LEAVE YOUR CAR OVERNIGHT BEFORE DOING THE ADJUSTMENTS !!!

[Spoon-Accord]

Like a firm grip kinda, goes in out and relatively easy but bites and skips/jerks a bit when you slide it.

Lol :D

if you do it this way, definately too tight, supposed to be light drag, not jerky until the feeler gauge sings and chirps LOL

[dougie_504]

Never said anything about singing and chirping. If you have a light drag but no jerking/skipping then it's too loose. That was your problem to begin with right? TROLLOLOL!

Its all subjective mate. Just get it right and remember the feeling and call it hat you want.

[VT3C]

I still think Dougie's description is SPOT ON.. it's meant to be biting a little bit, if slides too freely, when everything gets to operating temp it will be too loose. tighter is better = more lift HAHA.

[dougie_504]

^

Yup yup yup!

[Spoon-Accord]

Well me and mocchi did what Andy described and we got bad idle, I mean when it warms up, heat makes th expand, so you need to be between the tolerances honda provided which I didn't follow. I just kept on tightening it so that the lower spec fits but not much effort pulling the feeler in and out

I've had my fair share in motors and adjusting valves. Just this particular motor has me snuffed, even mocchi shook his head

[dougie_504]

Tighter side is better from what I've seen. It's all subjective though. Hard to explain to people in written words as opposed to showing them in person.

Just pay a qualified mechanic like 'stndrd' to show you. He does on-site work at a good price.

[Spoon-Accord]

yeh, it's all good. all sorted now, just saying.

it's one of those things you can't explain.

it's like sex, you say it feels good. but HOW good? LOL

[stndrd]

Yeah so long as it goes in and out and is not to tight but not to loose ay?

[dougie_504]

Like I said...the tighter side of the scale is superior...

[cbauto]

go between valve and rocker. (intake and exhaust going in.)

not between cam and rocker. ( from middle going out)

keep the drag consistent with every valve.
takes me longer than an hour tovdocit properly, consistent, even doing the one valve several times to get it right.

what oil you using? oil contributed to valvetrain noise too.

[stndrd]

So CBauto's Bludger knows better than the workshop manual?

[cbauto]

I've done it both ways. I like the results better from the way I describe.

I'm just contributing what I know. let others decide what's better.

[Spoon-Accord]

I tried to pm you, but no reply. See if you could help do it

[stndrd]

I replied asking where you were located and never heard back

[MRGRIM]

there is only one right way to do it perfect 1st time

have 3 feeler gauges at the ready
1st feeler gauge is 1tho smaller than spec
2nd feeler gauge is correct spec
3rd feeler gauge is 1tho bigger than spec

adjust with correct size then check with 1 & 3
you can work out the rest

[cbauto]

good idea, but unnecessary imo

also, you would need 6. 3 for intake and 3 for exhaust.
