How difficult is it to adjust valve clearances on 2003 1.2 8v? And where can you get the shims? Mine has only done 42000 but quite 'tappety'. Are there any special tools needed or can i improvise? Thanks for any advice

Well, if it's anything like the 1.2 8v engine in a 2000 Mk2 then it's not too bad but a bit faffy.

Apparently Fiat will sell you a shim removal tool but I levered the valve down with a large screwdriver and then wedged it in place with a small hardwood block - this needs to only engage with the edge of the carrier because you'll need the shim free so that you can flip it up with a small flat-bladed screwdriver.

If you find that a couple need re-shimming then it might be worth your while to pop out and replace each of the shims in turn (do this one at a time AND remember where they came from) and check the values on them. That way you may be able to swap a few around and save having to buy some more.

Fiat will sell you the shims (if they have them in stock) but I've also read that shims from some Ford Diesel engines have the same dimensions.

You'll also need to reseal the camshaft cover with four blobs of instant gasket (or similar) where it curves over the camshaft bearings and may want to replace its gasket.

Hi
I have just measured my valve clearances and the inlets are fine at 0.4mm but the exhaust valves are 0.35mm. Should i reshim?

cheers

Yes. You can also get shims from Fluffy the Impaler (Big Mick) at Eurocarcare in Derby. Google for the phone number.

There's a fairly good description/analysis in the Mk1 Punto and Cinquecento Haynes Manuals.
