[Vwdiesel] Blow-by * Additives and Flush

[Ludovic Fremaux]

I acquired a 1983 Vanagon Westfalia diesel a few months ago.

This is the third engine in that car and it is said to have 75k mi.The
engine is a 1.6 NA and must be from a Golf or Jetta.
There is some blow-by coming from the dipstick orifice. It's spraying
oil that finally drips on the alternator and water pump belt. Blow-by
also comes from the valves cover oil cap. Otherwise the engine does not
seem to lack too much power.

Before investigating any further, I'd like to try additives, either or
both to the oil and fuel.

So far I found quit a few for oil:

Lubegard Engine Flush
Amsoil Engine Flush
Marvel Mystery Oil
Bell's Super Premium DEE-ZOL
Gunk Diesel-Tone
Bardhal Motor Flush
Swepco 503
Lubro Moly Pro-line Engine Flush
Wynn's Engine tune up

Any first hand experience with these products? Are they really effective
to free rings and valves?

Thanks to all of you, I learnt a lot reading your posts.
