So at the back of the block on the passenger side there is a hole in the block that is supposed to be there that is one of a kind compaired to all the other water holes on the top. I accidentally dropped a piece of wood in this hole and I was wondering where this hole leads too. The hole is only visible with the head off. Thank you.

 

And here I thought you liked your 22re so much it gave you.........

Anyhoo what are you asking?? should you get it out? I'm gonna say no matter what hole it is wood shouldn't be in it.

 

I discovered it is in the oil pan which doesnt excite me. Any ideas of how to get it out without taking the oil pan off?

 

Give some more info here, did you just rebuild and it is back in the truck?? How do you know its in the pan? what kind of truck? I would imagine the pan drops enough to maybe fish it out?
