85 C10 removing oil pan

[Zach079xxx]

I had my abc 350 rebuilt about a month ago, ran great. I drove it to school 45 miles on the interstate at 70 MPH ran great but on the way home something came loose. Either my manifolds are rattling like a SOB or its my high volume oil pump. I've read the the inlet tube should be welded / locktite on, but I didn't install it and don't know if it was or not. I changed the oil today because it needed it, should've done it then honestly.. No metal was in it. I added the new oil and filter back in but now I'm thinking of draining it and pulling the pan to see if its my oil pump rattling so bad..

Can I remove it without with the engine in the truck? Again, its an 85 GMC C10 2WD

Whats the torque rating on the pan? Thanks guys
