Compression and leak down test should usually be the first course in these
diagnostic situations. Valve adjustments are not a fix by themselves. If the
valves show signs of leakage another repair is most likely needed.

Subject: Enlightment needed Valves Question WBX 1.9

Hello List,

It was suggested to me that the valves on my Vanagon are causing the lack of
smooth idle and then the subsequent lack of power under load and the
stalling of the engine. This may explain that "ppfffff" sounding backfire
that I hear, like a lean backfire coming from the air cleaner while on 2nd
gear.

I know, I know we have hydraulic valves and they should not need adjustment.
That was told to me and understood by the person giving me the tip. He
explained that even so, in freaky instances this valves could still float
and cause a lack of compression.

I have not done a compression test and more than likely will let the
mechanic do it since my time has ran out on working on this van (baby coming
soon ~3 wks)

I wondered if anyone has experienced something similar?
Thanks,
El t.
