ROOF LEAKING !!!!

[Jipjob]

How about a bucket of snow coat?? No only kidding and your idea reminded me of
how we oust to test shipboard condenser tube nest. Same Idea put pressure on
the inside of the turbine area and check with bubble soap for leaks in either
inlet head of condenser or outlet. We also oust to use a green fluorescent dye
with a florescent light to check for minor packing leaks.

of it. GREAT IDEA! I'm happy your still here on the Forums. Sorry about not
signing my post, Kurt Horvath 95 PT 42 10AC. The leak is in the bedroom rear,
road side just dripping down from the wire tunnel between the closet and the
bed. I've looked up into it with a fiber optic scope to no avail. The fiberglass
rear cap had a large gap between it and the body but sealing it didn't help. As
high up as it is it's probably the Cat Walks, or Goat Rails,
