I tried marvel in the gas tank to no avail.  The driver's side rear
cylinder has 0 compression.  I really want to do the work that is required
to get my van back on the road myself so I am hoping that someone on the
list can help me get started.

What do I look for when I pull the valve cover off of that side?  Or, is
there another way I should go about it?

Thanks so much,
