Subject: repeatedly blowing head gasket-what I found
Content-Type: text/plain; charset="iso-8859-1"
What I found-
The pits in the water jacket are minimal. Perhaps 1/4 of the width of the
jacket, and not engaging the edge. The studs go two ways: The four on the
top are corroded. Only one of the lower group is. One of the lower studs
appears to have rotated deeper into the case than the other three by about
3mm, or maybe those other three came out with the nuts. Or maybe they're
stretched, but that seems extreme. Regardless, the three that are farther
out will not go in any more.
Anyone still follow this?
I gather that I'll need to replace the corroded studs and nuts, but could
this really cause what I've seen?
Thanks for the patience and all the suggestions,
Mark
