I had to take the oil pan off to be able to work on the front and rear covers. While it was off, it was a good time to install some new parts down there.
People usually modify the original oil deflector to work with this oil pan. It requires cutting a fourth of it completely off and trimming a few other spots, all for proper clearance. GM actually makes a newer oil deflector that eliminates most of these modifications. I only hade to make one small mod for the new oil pump pickup tube.
Here is the new deflector...
I removed the old deflector. Here is the old vs new...
This is the one, small modification that I had to make for clearance to the new pickup tube...
New deflector and pick up tube installed. Torqued to proper specs...
Pulled the spark plugs and rotated the crank so I could check for clearance issues but I didn't see anything.
