Tat..Tat Noise in Engine

[Peter Golledge]

Max,

If the lifters have never been replaced then it is very likely they are the
cause.  Replace the whole lot otherwise you will be pulling the camshaft
again.  You should be changing the timing belt at 300,000 km so I would do
it then or do the timing belt early.  Since you have to mess with the water
pump/belt to get the camshaft out you might as well do the whole lot at the
same time.

Subject: Tat..Tat Noise in Engine

I have a MC engine in Type 44 Quattro, with turbo charger  with 285,000 km.
when idling it makes a tat...tat....tat......tat.......tat...noise from top
part of engine. When inside of car noise is not heard. Engine never
overheats, starts immediately. Sometimes there is white smoke coming out of
exhaust just after starting. I alternately fill tank with RON 89 and 91.
What could problem be?...if any? Gasoline may be issue. Could Rislone
additive help?
