[Vwdiesel] Blow-by * Additives and Flus

[Ludovic Fremaux]

I am waiting for a compression tester to arrive next week. I will then
measure compression on the cylinders and while the injectors are out I
will try your recipe.

I removed and cleaned the valve cover last week, it was not clogged.
Neither was the "Y shape" pipe going from the cover to the intake
manifold. I took out the intake manifold as well (being the original
Vanagon 175k mi I thought it could be the problem). There was a small
amount of tar into the 2 conducts but nothing that would restrain the
flow of blow-by. Cleaning the manifold didn't make much difference.

I could not find any breather on the block. Where is it supposed to be
located?

Thanks.

Ludovic
