1984 4k - no start

[John Lagnese]

Probably the crankcase ventilation system lets in too much air.

I own two VW QSWs, '85 & '87, which as you know share the same engine tranny
as in the 4KQ and engine still runs fine with either the oil cap off on the
valve cover or dip stick out.

Earlier this year someone commented that on Audis' MC1 and MC2 engine codes
the car would run poorly if at all if the dipstick was either loose or off.

I could not believe it so just for the heck of it, the next day I went to
test that theory on my '86 Audi 5KTQ.

Indeed, while running at idle speed even after warmed up, if I took the
dipstick out enough for seal in it to loose contact the engine started
sputtering a few seconds before it quit.

The same resulted when I remove the oil cap off of the valve conver.

I guess that's normal. Any reason for it to quit under such scenarios?
