I failed to post that it's a 1.9L with 240K +/- on it. I run 10W40 High
Mileage whatever brand is on sale. And the flicker only occurs after it well
warmed up. I believe an oil change is due so hopefully that will do the
trick. After all aren't all the repairs/remedies we do to keep our Vanagons
on the road tricks of one sort or another? I just hope the magic lasts
forever.
