Default Tappety Engine

Morning All

My engine has developed that tappety sound so my guess is I need to order some tappets. My question is whilst I've got the engine partially dismantled are there any other jobs I could be doing at the same time?

Does anyone have a good video on tappet replacement? Thanks in advance.

My 1.6 is the same when Rev come back to idle it taps then stops. Does the camshaft need changed at the same time on these?

This is quite a big job and these engines are know to be a bit tappey. First of all, are you using the correct grade of oil? Then, has it been changed frequently? You can use a flushing oil to try and free them up. If they only tap for a short while on start up, I would not worry too much. If the car isn't used very often you need to change the oil and filter every year at least.

The Audi service manual states: "run engine until radiator fan comes on at least once. Bring engine speed to approximately 2500 rpm for 2 minutes. If valve lifter is still noisy, replace as follows"

I did this once on my old rattly coupe 20v and just before the 2 mins were up, all the noisy lifters went quiet.
