16v tappets, etc

[benmk1]

well thanks for the advice fellas, didn't expect wwIII (or should that be IV )
will change the oil and filter, an put a flush in first......if this helps, which i doubt as the oil looks fresh, then many thanks.
If it's still noisey will get tappets from vw. I did motor vehicle studies in school , way back i know, an i remember adjusting them but not replacing, is this straight forward?
I haven't got a haynes yet either.
Cheers

Hydraulic tappets become clogged up over time especially if the the oil isn't changed regularly enough. They usually start tapping when cold as the oil takes longer to fill them up, once the engine is warm and the oils thins they fill up and the tapping goes away. Once they become really bad the tapping will be present regardless of engine temperature.
Wynns make a hydraulic tappet cleaner, you put it in your engine for a couple of hundred miles then change your oil.
I had a passat once with really noisy tappets I used the wynns stuff and was really impressed it shut them up completely, I'd recommend it anyday.

You can also drain out about a liter of your oil and top it up with auto transmission fluid. Take the car out and trash it about again the do an oil change. The high detergent in the tranny fluid cleans like mad. Just don'e leave it in there long as it thins the oil quite a bit.

i find wyns engine flush when you change the oil quietens them down for a bit

exactly.

from what i picked up the main reasons they tap is because they are worn out, and the oil seal they need to develop to work properly doesn't form very well, or breaks down very quickly.

so whilst the oil cleaner gets rid of some of the rubbish, it doesn't compensate for wear.

at which point you need my patent pending:

was ?15 from vw bout 5 months ago

dont get the original tappets from vw get the updated ones off of newer cars cos they are loads lighter and a lot quieter on start up

the weight of the tappets make no difference. if the engine has adequate oil pressure they'll be silent from the start. if the engine doesn't ahve the correct oil pressure then they will click for a few moments until the engine comes up to pressure.

buy the real things. no point in cutting a corner when you dont have to.

and they are updated ones from vw as are fitted to mk 4's etc. i didnt mean german/swedish pants! 

lower weight means easier reving cos the valves can open faster and close faster

you people have strange ideas about what counts for performance modifications....
