high oil pressure

My wife called me from her '02 X to tell me her oil pressure gauge is pegged. She hasn't driven the Jeep in a long time so she didn't remember what it "usually" is. When she got home I looked at it and it wasn't pegged but was reading just below 80 psi at idle on a very hot day. The owners manual indicates normal pressure between 45-65 psi. I'm generally concerned with low oil pressure but do I have a problem here at 80 psi?

I would bleed the lines just to make sure, sounds like you might have some sludge build up, causing an increase in pressure. The increased pressure might put excessive wear on the seals, and cause them to leak.

Bleed the lines??? What in the world does that mean?

You don't bleed oil lines, I'm not sure what he was talking about. I'd first change out the oil pressure sender which is mounted next to the oil filter. The sender is responsible for most oil pressure gauge problems. Before actually buying it though, unplug its connector first and clean it, then reseat the connector. Could just be a dirty/weak connector that connects the wiring to the sender.

When you have a choice, buy American.

Oops, my head was in the clouds, has been all day, I have a cold and am doped up on robotussin . What I think I meant to say was to drain the old oil out, being that she hadn't driven it in a while.

Thanks. I'll give that a try.
