I'm prepping a recently rebuilt 235 to replace the tired 216 in my 49 3/4 ton. The front engine plate lacked the square holes for the truck mount carriage bolts so I had to remove it for the necessary modifications. When I removed the oil pan, to access those pesky bottom timing cover bolts, I noticed that the oil pickup screen assembly was tipped up quite far from horizontal to the driver side of the engine. I tried to rotate the pipe to achieve a more horizontal orientation but that resulted in contact between the pipe and the right connecting rod stud on the #5 cylinder. With the pipe rotated back just far enough to restore clearance I measured and determined the clearance between the pick up screen and the bottom of the pan was roughly 3/8".
The only shop manual I have right now is for the old splash oiler. The appropriate manual is on order and will be arriving via snail mail. In the meantime, can anyone help me out with the proper orientation procedure?
This is how I set mine up. The pan and pick up is 55-57 passenger. My understanding is that early 55 truck used the 54 style pan, later 55 used the 55-57 style pick up. The pick up for 58 passenger car was different, as was the 59-62, to accommodate differently configured pans. Not sure about the trucks but spitballing here, likely the same. But all of the 55 and up pickups should fit any of the later blocks and not interfere with the no. 5 rod although it does come close. Any chance someone has been in this motor before? Maybe using a pick up from an earlier motor or is your pick up tweaked? Can you post a photos?
Why not put the pickup tube in a vise and bend it slightly until there is sufficient connecting rod clearance? It's not like there's anything precision about where the pipe is routed. As long as the oil gets from the pan to the pump, it's all good! Jerry

Thanks for your reply. My donor motor came from a 57 chevy 210, casting #3837004, so same series as your motor. Your picture looks exactly like my setup. I suspect possibly the person who rebuilt my motor may have tightened the pump to block line before tightening the pump lock bolt to properly index the pump alignment. I'll loosen everything and retighten in the proper order tomorrow and see if that gets me out of this pickle
Might be the case. The correct way to install the pump bolt and lock nut is to install the pump with out the lines, Turn the pointed bolt in until it bottoms out and the pump does not move. Then back off just a bit. the pump should wiggle just ever so slightly. Tighten up the jam nut and then install the lines. The pickup does get pre installed onto the pump. Make the lines meet the pump as opposed to forcing the pump in to accommodate the lines. You really should not have any interference with the no. 5 rod and the pick up tube.

Thanks for the guidance. I hit a snag this morning when I couldn't find a wrench to fit the retainer lock nut. 9/16 too small; 5/8 too big. I hauled a whole bucket of misc. extra wrenches to the local thrift store a couple months ago - shoulda known better. I just ordered a 19/32 (none available in my local shops). If it fits I'll get everything locked down in the proper sequence and hope for the best. If there's still contact with #5 rod I might have to find another pickup tube or bend the old one.
