breather hose thanks/dancing oil pressure gauge

["Eric Friedman/Creative Showcase, LLC." <creativeshowcase@nac.net>]

Did some odds and ends for service to the car earlier this morning: cleaned
the K&N, changed the spark plugs to the Bosch 4 prong, new rear brake pads,
oil pan gasket , valve cover gaskets and those breather hoses.  You guys
were so right-they were the consistency of chewing gum.  The ends literally
broke off.  Thanks for the posting on that.

Tranny flush next week.  Timing/VBelt, water pump and thermostat in 3 weeks.

Hey, no one had any thoughts on what's making my oil pressure gauge dance?
A sending unit of some sort?
