DIY tappet adjustment

depends on the engine

SOHC you have no choice and it gets done at the valve.
DOCH I do it from the outside and check it from the inside to make sure its not to tight. DOHC get doen at the camshaft

Sorry if this has been asked before, but I couldn't find anywhere:

Anyone know the exact clearance specs for EK4 B16A2 tappets?

Thanks in advance.

you mean B16A2

OOPS! (fixed)

Thanks for that ECU-MAN ;)

Looks like a good writeup, I need to get this done on my holidays my tappets are getting louder.

Any chance of getting the pics back up?

Cheers.

pics are back up

Sorry to bring thread back from dead, but these clearances are for cold or hot motor? And they should be the same clearance required on a b18c from what ive read, Ive noticed it isnt as easy adjusting the tappets on a DOHC as it is on the SOHC, if someone could confirm this that would be great, thanks

the measurements are for a stone cold engine.make sure it has been left not running for at least a couple of hours. its more difficult on DOHC,but its definitely doable. you measure between the cam lobe and the rocker.those measurements that you have are correct,correct for all b series vtec.i didnt have a the special tool and i didnt make one,just used socket to undo the nut,turn a lil with screwdriver to the right feel with the feeler guage then do up the nut,check and redo it until the feeler gauge feels good after the nut has been tightened,you get the hang of it after 10 or so goes

^ good stuff thanks champ

I did this not long ago on my B20, the DIY helped heaps.

In regards to the 'special tool', I couldn't find one anywhere and so I tried to find a 10mm 90' spanner that would fit in the limited space - with no luck. The last shop I went to I ended up finding a 10mm 'brake bleed' spaner which fits perfectly!

Thanks John! It's so easy to understand by your write up.Especially cause I got a SOH Banger :)
When my tappets are adjusted my car runs so much better.So I'm gonna be doing this every 10,000km now I know how to do it.I spent a week at my mechanics over the last month and learnt heaps.But I didn't do this.Now I gotta try by myself.I really gotta invest in some tools.I want an air gun.
Oh Thanks again John!!!
