adjusted my tappets today (because Ka's are noisy and this happens quite alot!)

for those of you who are thinking of doing theirs:

Exhaust valves should be 0.5mm and inlets 0.2mm and are checked / adjusted cold.

Gasket is a cork item which usually breaks up when you move the cover. Even at a Ford dealer they're only a couple of quid, so you might as well replace it.

(and also the old one is a ball ache to remove. i suggest a small hammer n a flat head screwdriver or chisel to gently get off the old cork gasket!)

You just need a spanner for the rocker cover bolts, and another for the rocker arm bolts / adjusters, plus of course a good set of feeler gauges.

The rocker arm adjusters wind in against a spring which is supposed to eliminate the need for a locknut. Therefore, you just turn the bolt clockwise to reduce clearance, and anti-clockwise to increase it - there are no locknuts to worry about.

It's very simple and logical when you see it

hope anyone finds this helpful :) Hman

also a good trick i learnt was if rockers are worn then you cant measure the clearence properly so to quieten them up you need to remove the rocker shaft and with some 400 wet and dry paper wrap it around a flat file and gently sand the rocker faces flat again then replace rockers and re adjust , i have done this many times and found it quietens them much more than just adjusting
