after doing some work under the hood on my 3.8 '90 Tbird, I had a whistling
under the hood that I only 4 days later got to investigate..
I drove maybe 40-50 miles (mostly HARD trying to get it warmed up) during
this time.. I found that I had inadvertantly knocked the PCV valve out of
the valve cover, so the valve just hung there. my question is, does this
have the potential to cause any actual damage?
