Any garage should be able to do it for a few quid, or
If you remove the oil cap can you see the cam? or is there a plastic cover?
If there is no cover then you should see the oil being chucked everywhere by time the engine is up to operating temperature.

tappets tend to make more of a ticking noise rather than a bang and clank

there is a good chance the exhaust manifold is leaking at the head!

The knocking sound could be the big end on the way out :undecided: , my bottom end started to rattle, but it has just done 178k & it's has been replaced with a 2.0L bottom end  :evil:

The Big end and Main end Bearings tend to rumble, like a wheel bearing style noise. Tappets tend to 'tap'.
Like HC-animal said, it could be Exhaust manifold or down pipe? Open bonnet, when engines running listen to where abouts noise is coming from..if it back of engine then it could be exhaust, if its bottom of engine its likely to be big ends, and tappets and inectors are on top of engine.

Check your oil level, sounds obvious but always best to check that first!  :rolleyes:
If thats fine then you can get some oil treatment, not 100% sure what its called tho!   :undecided:

Tappets a reasonably straight forward job, doesn't take too long. Parts about £80 If I remember right  :tongue:

If its the tappets then the id do the following.

Dump all the oil and throw away the oil filter.

Replace the oil filter with a genuine vw one as they have a non return valve and fill up with vw syntha silver oil

If that doesent help then there is a tappet treatment fluid you add to the oil that can help. I think its made by wyns.

But also i had really noisy tappets until i got my timing corrected and now they are silent. Worth getting that checked too at a garage if like me you have never done it yourself.
