Hi All,

Exhaust system job in progress!

While I took apart the exhaust system (that baby was
rough! � to say the least), I noticed the following:

1. The cylinder heads had a number imprinted inside
the exhaust outlets (see:
http://www.esu.edu/~gstylia/vw/Cyl3b.htm ). It looked
like the cylinders were numbered. The only difference
is that cylinder 1 was indeed 1, cylinder 3 was indeed
3, but cylinder 2 was also 1 and cylinder 4 was also
3. What�s up with that?

2. Inside the cylinders� exhaust outlets again, I
noticed some type of a rod (see:
http://www.esu.edu/~gstylia/vw/Cyl3qa.htm ). What
would those be, exposed to such a high frying heat?
One of them looked like it was partially melted. I
could be wrong. I�ll check tomorrow.

3. I noticed that one cylinder had white powder
deposits, where the other three were black. What is
the significance of those deposits?

4. I removed the crossover pipes� studs from the
cylinder heads. I had to wrestle with one of them, but
the others came off easily. I think I made the mistake
to clean the threads of the female stud receiving
holes on the cylinder heads. I say that because the
new studs went in very easily and when I am ready to
put the lock nuts, they will give. Can I use
threadlocker compound to allow for some resistance?
Input?

It looks like studs work better when it comes to
positioning the crossover pipes. In the process, I
found out that 2 of the lower studs are longer (40mm),
in order to accommodate the attachment of push rods�
protective plates. The rest of them should be 38mm).
The bolts should be 30mm. Somehow, my new crossover
pipes do not fit. I may have to use the old one
(original, by the way� 21 yrs old). Tomorrow will
tell.
