I had a One of the plastic timing chain guides come apart and I need to take off the oil pan to retrieve at least 2 broken pieces. I have all the bolts out including the 4 transmission mounting bolts and the lower AC compressor bolt and the pan won't budge. I have tried prying on all the "pry points" and hammered on the pan with a dead blow hammer. I even threaded in a large bolt into one of the threaded bosses on the right side of the pan and pushed straight down through the engine compartment with a 40 inch crowbar.
Any ideas?

 

Pull up the engine PDF I sent you and go to page 250, the oil pan removal procedure starts there, I don't think you missed any bolts....but the GM sealant might be a heck of a lot stronger than I ever figured.

 

Dynamite!!!!!

 

I gave up on the oil pan for now. I don't think the pieces will hurt anything.
