| Subject: | Re: Wet Dog Syndrome On Shutdown |
A final update on this.
After talking to Lord, the indication was that I had a mount (top
passenger side) that had run its cycle. I couldn't get a good answer on
what the lifetime of a mount should be. I assume there's too many
variables. I also don't recall checking the cure date stamped on the
box when I originally mounted the engine three years ago. I'm guessing
that Vans stock may not be the "freshest" in that regard.
I got new mounts installed and the extra shake and "knocking" at idle
and shutdown is gone. I can't believe the difference. I noted that
even the "new" mounts I purchased from ACS had a cure date of 1/2015, so
even they were over a year old in the box.
Anyway, I'm a happy camper now.
