Is this pinging I'm hearing?

Hey Guys,

Just picked up my first VW about a month ago and think I've found my
new life-long hobbie! She's a 1980 Westfalia, Air-cooled, 2.0L fuel
injected (2000cc I believe).

My problem is this:

I've done a ton of reading all over the net but I can't quite confirm
if the noise I'm hearing is pinging or not.

>From all of the posts I've read I'm thinking that pinging only
(usually) occurs when the engine is at a higher RPM with a load on the
engine. The sound I'm hearing can be described just as pinging is
generally described - "metalic tinging sound - similar the a bee-bee in
a glass jar" coming from the rear end.

The reason I'm not sure if it's in fact pinging or not is because the
sound happens as long as the van is in motion. Let me explain further
- I'll be clipping along in town at about 60 km/h in 4th gear - the
engine is pinging away - I press the clutch in to take load off of the
engine (at least I think that would take the load off - I'm a newbie)
and the pinging continues as I coast ... when I hit about 20 km/h the
sound seems to have completely faded away. There is never any clunking
or hard knocking that I read goes hand in hand with the pinging noise.

I know pinging can be attributed to over heating and timing - The
engine runs like a champ (although I've got to replace the push rod
tubes and seals as she's leaving quite the mark wherever I park) - I
don't have a CHT guage in it at the moment but plan on installing one
very soon as I'd like to take her up north in a few weeks (about 9hrs
each way so I need to narrow down if this is pinging or something else
- cuz if it's pinging I'll have to take another vehicle :-( ). I did
the dipstick test tonight after running the van around town for about
20 minutes and the stick was quite warm - though, not too hot that I
had to let go of the stick but if it was 20% warmer I'm not sure I
could have held on to it.

That's about it ... Sorry for being so long winded - just wanted to be
sure to get everything across.

Thanks in advance for any advice/knowledge you pros' can lay down for
me.

Not pinging.

Ping only occurs under load.

I would look at the CV joints or maybe stub axle bearings/drums/brakes.

You might get some ideas by jacking each rear wheel and spinning
by hand.

Thanks for the reply Jim. Good to hear you don't think it's pinging.
I'll jack her up tomorrow after work and see what I can find..

I'd be in 3rd gear at 60k !

The engine wont have to work as hard.

For one hot second I was wondering why you'd drive that poor bug like
you stole it, Rich.



The next second it occurred to me that it is 60 Kilometers/h, not 60
Miles/h.....

Was thinking that perhaps a tornado is a different car over there - but
a bus with that much HP would be a monster

Rich, you were torn between a bus and a tornado?

Cool!! A friend of mine here had one of those - actually ran NOX as
well. Not sure what was up with that, because it had plenty of OOOOMPH
all by itself.

And , as I guess you have all figured, I meant to type

"It's a bus , not a bug"
