K5 Oil Leak

[catfishblues]

My 87 Burb has developed a nasty leak somewhere around the oil pressure sender. I couldn't tell exactly where tonight, it's kinda cluttered in that area with the filter, oil cooler lines, sender, 90° fitting for the sender, etc. all right there. I wanted to know if anybody knew of a common leakage area there before I tore into it to determine the source. Are these pressure senders known to give out where the body is crimped together? That almost appears to be where it's coming from. Thanks!

THe cooler lines and the seals/ gaskets for the cooler puck are known to spew from time to time.

could also be a valve cover gasket that finally let go.

hope you have lots of brake cleaner
