Noisy tapets on 186

hey, does any1 know how to solve the problem of noisy tapets on a 186 red engine ? ( i think thats the problem ) i have a holden hr premier, and it makes a ticking noise at idle :( the ticking doesnt increase when i accelerate tho. so i think/hope its nothing too serious, but it would be nice to fix it.

if it was the tappets it would increase when you accelerate....
if it's remaining constant it's probably not from the motor....
have another listen...

You can adjust the tappets on a 186 - but it is messy. Tou need to take the rocker cover off and while the engine is idling and warm - gently tighten the rocker nuts until the yicking stops - if you go too far it will start to rough cause the valve will be slightly open.

have fun

Try doing a oil change? if the oil is old and thin it will make the tappets sound like a freight train under the bonnet...

Good luck with it all.
