A typical issue with all WasserBoxers, with the archives full of the
correct solutions and a bunch of other junk.

Three things to verify:

1) Verify you have the factory approved filter. Mahle/Mann/VW, always a
black housing.
2) Verify the weight of oil is correct for conditions.
3) Ignore tappet noises after sitting for several days if they quiet down
after up to 20 minutes driving. A ten mile drive resolves this lifter drain
down issue 90% of the time.

Half the time a noisy WasserBoxer comes to me, a change back to correct oil
weight and/or factory filter instantly resolves the complaint.

I am in the middle of servicing a WasserBoxer motor that came in very
noisy, tappets and more. This is with all three above items verified. Will
report on all the steps taken to improve and correct these motor noise
issues as I will finish with it later today.
