Just to pass along something interesting, mine is an 81 air cooled with
lots of miles on it. Often when it sits more than a few days, it is one
noisy bugger when I start it up, summer or winter, regardless of the oil
of choice. Lifters or whatever are really loud.

I am used to it, and what I have noticed is that it has sat for about six
weeks outside, on a very slight incline in the driveway, nose up. Not a
lot of hill, but its enough of an incline to make the basketball games
interesting.....

Anyway, when I would start it up after sitting on this small tilt, no
excessive noise, clatter, or banging. Did it about three or four times in
six weeks. Nothing. Sounded just perfect.

I put it in the garage a few days ago for the CV joint adventure, and when
I started it up today, the racket was back, and the clatter was pretty
intense for about fifteen minutes.....

The oil level is fine, so it almost looks like, in my case, sitting on a
slight incline appears to nearly eliminate the "lifter syndrome" or
clattering, or whatever one wishes to call it.

Nothing spectacular, but I guess maybe I should get a pair of ramps and
park it nose up when its in the garage. Can't really leave it out on the
hill, as last year someone shot out the back window....

Anyway, just something to say that is not related to the CV joints.
