I have a 2003 z71 suburban 4wd, I recently replaced the valve cover gaskets and oil pressure switch due to small oil leaks. Now I have a very steady oil leak that was much worse than before doing gaskets and pressure switch. Any insight would be much appreciated.

 

You should be able to determine whether the sender or which valve cover gasket is leaking oil. Clean off real well, do visible examination, use talcum powder or UV dye/goggles if necessary.

 

You need to be more specific as to where the leak is, so we can better help.
