still leaking oil after new valve covers, maybe rear main seal? & oil switch swap?

1. Its hard to tell cuz everything is so covered in oil, rear spark plug wires "valve covers", and now i notice oil leak is directly under back of engine.
Think i'm going to have to whip out the pressure washer and clean some stuff up.

2. Have an 82 blazer with a 3 wire 2 prong "l l" oil pressure sitch plug. And my motor not sure what year it came from like an 84-86 suburban has a 2 prong in block above oil filter. Can i splice the 3 wire to make it work or buy the right sensor to put in block? Have heard that they also put some in back of block behind air cleaner?

3. Also going from a 4 peice oil pan seal to a felpro 1 peice?
You guys ever use the expensive ones, metal dipped in rubber, they work for oil pan?

1. Yep, clean the engine and find where the leak is coming from before replacing any seals. One thing you might look at is the PCV valve, if it is clogged then you could be building up enough oil pressure to push past your gaskets/seals even if they are new. I had the this problem on a new crate motor (zz383) because I insisted on running valve cover breathers instead of a PCV.
2. You should be able to get the right sensor for your year blazer from an auto parts store.
3. Is the oil pan leaking? Be sure before you replace the seal. I've not had any problems with the one piece seals.
