Valve Clearances

I need to adjust the tappets on my 2005 Pica and cannot find the setting to use. Can anyone advise me: Yes, Swampduck, I do want to do them

Thanks, Brettonboy.

I guess your car engine uses hydraulic valve lifters, and if so there's no setting.

Thanks Ron for the quick reply. I have a definite slight rattle so it probably just needsa good top-end service and clean up. Thanks again

Hi, no hydraulics, settings are cold settings - intake valves 0.28 - exhaust valves 0.33 - this is for the 1.1 - 12valve motor and I from what I know they used the same motor through all the years even in the latest ones! Good luck - really hard to get to them...

Hi, the picanto 1.1 has rocker arms and adjuster screws.
The setting for cold adjustment are 0.2mm intake 0.25mm Exhaust
and the settings for hot adjustment are 0.1mm intake and 0.17mm Exhaust.
I am quoting from a spanish picanto motor manual I found on the emule network.

I didn't realise that there were new engines still using adjustable rockers.

I know this is an old thread but did my tappets today. All clearances were tight. This suprised me somewhat as i had some tappet noise. I can understand why all were tight after 100,000 and also running lpg doesnt help the vv seats.

After adjustment the idle seems better and the misfire that i seem to be constantly casing on cylinder 4 seems to have gone. I still have a some tappet noise but have nothing to compare it with. Does your picanto have any tappet noise. Mine is just audible over the engine noise.

Would there be any chance of your writing some instructions and/or posting pictures about how to do this job? It's the only job I've not been able to complete on my 2005's 120,000Km service. (I managed everythign else without garage help) The car *sounds* fine, though.

I've previsouly adjusted valves on an old Austin Mini, but that was easy - I just took off the rocker cover and everything I needed to access was there. But it looks to me like the 2005 Picanto's fuel injection array (if that's the correct word) sits right over the top of the engine cover and I'm a little nervous about taking the fuel injectors apart.

What did you have to do, or which parts did you have to remove in order to get access to the valve adjusters? I'm guessing they're right underneath the plastic engine cover, are they? But it just looks to me like other parts need to be removed first before the plastic engine cover can be removed.

Any advice would be appreciated!

Sorry for taking so long to reply, I have not been on the forum for a while. The plastic air box need to come off and then you have access to the metal cam cover. One bolt on the cover is hard to remove due to the air intake being in the way but I managed to get it with a short socket and coupling. Then it's straight forward. No need to touch the injectors.

Usual routine of tdc no 1 cylinder and adjust and then move along to the rest.

I can't post pictures just yet but may be able to in about 5 weeks when I come back.
