oil sender leak

This week will be the fifth time I have had my 07 PT in for warrenty work on an oil leak from the oil pressure sender switch. The last time was in December and the dealer claimed it was repaied. I drove the car home and parked it for the winter. Last week spring was here and took it for a drive. I went to change the oil and guess what it was leaking yet again this time the worst ever. Yes it is in the back of the engine and very hard to get to. Yes I check it myself I removed the air box and fuse box and could get to it. since it is still warrened I left it alone. Now lets be real it 's an oil sender common to millions of engines a little tape and screw it in and plug the wire on. What is the problem here. I know I am an Amature mechanic. Just did a clutch 77-d200 clutch fan astro brakes astro. ecm tracker, rear wheel bearing subaru legacy. This was all last month. Can a profession garage charging $76.00 / hr fix this car? should I call a plumber?

While I at it has anyone else had to have their 2007 PT automatic re programed every 6 months? Is this right?

if it is a mopar part it sould be under warranty 1 year warranty on parts if installed at the dealer
