I was talking with a colleague of mine yesterday who is/was an experienced
GM mechanic. In discussing things VW and the headleaks that our beloved
wasser boxer's develop he mentioned a GM product that was commonly used in
the aluminum engines to deal with the "pitting" problems that those engines
were prone to.
The product is simply a GM COOLING SYSTEM SEAL TABS (part no. 1051687). The
make up (as shown on the back of the pkg) states it is made from GINGER,
ALMOND SHELL & BORIC ACID.

Do any of you engine experts know anything of this product or have any
experience with it ? It sound to me like it could be a decent "preventative"
to use annually in the system ?....what say ? I spoke to my (experienced) VW
mechanic & he was unaware of the product. I'm going to take him some and
(maybe) start using them in between semi-annual coolant changes.
