Topic: 440 build oiling concern.... (Read 341 times)

I put together my 440 a few weeks back and when installing the oil pickup I was only able to screw it in about a turn and a quarter. This bothered me a great deal but I went ahead and sealed up the bottom end and installed the pump because it was very tight(had to use a pipe wrench to turn it loose) and it really cannot go anywhere due to the windage tray and pan design. I am using the Milodon 30930 pan and 3/8" Milodon pick-up 18325. Is this something that is going to cause a problem or is it nothing to really worry about.
I was about to place an order through 440source and noticed they were offering both external swinging and static pickups. Is this a better option in my situation? I noticed all the external pickups mentioned blocking off the internal pickup, which worries me as for how to if the threads are messed up. But I know very little about these external systems so any information as for what is needed to complete this conversion would be much appreciated.

One and a quarter turns does not seam to be alot, but with tapered pipe threads it's a matter of depth of engagement. As long as you've got a good portion of the pickup threaded into the block and it's well sealed to the block i.e. no suction air leaks you shoul be O.K. Just my 2cts. Willie

Has anyone else had problems like this? I really don't think that my threads are messed up. The guy I bought the short block from had made a spacer out of 3/8" threaded steel pipe to lengthen the stock pickup to be used with a Hemi pan that he had fabricated to hold 7 quarts. This little spacer matched the threads on my pickup and would screw into the block 4 or 5 turns. My pickup was also very difficult to get it to start threading into the block. Its almost like the threads were oversized.

Id bet the pickup was slightly egg shaped at the threads.
Did you use any sealer or teflon tape on the threads?
I would try a different pickup or a 3/8" pipe nipple to check the block threads.

don't panic everyone. Just take the pick out and run a 3/8 pipe die down it, a little at a time until you get good engagement. I definately wouldn't want to risk it falling off. there's just no way you could react in time to save your engine

Depending on what pan you have, Melling(any OEM PARTS STORE can order a new pick-up--I get mine from O'reillys for the 699/187 Oil Pan for C bodys) |

I've seen that many times before. The factory pickup tubes fit nice. Moroso and Milodon are tight. Tap the bock or run a die on the tube but DO NOT put teflon tape on the pickup and drive it in. You WILL crack the boss. If you must seal it, use a little Brush on Blue Block.

I'm not worried about it falling out. That thing is in there tight and the windage tray won't even allow it to turn 1/16th of a turn. I'm worried about it sealing. I have ran a 3/8" nipple down it like I said and it was tight but it continued to turn for about 5 turns before getting very tight. I've seen that many times before.

I know I can run a die over the tube but is it okay to tap the block with it this far together? I know to use vasoline on it to catch the shavings but this safe to do? I'm tempted to just go to an external pickup....either way I'm going to fix it but what would you all do? |

Turn the engine right side up on the stand so any shavings fall down. Use grease on the tap and turn the tap in slowly so the tap doesn't crack the block. You could also shop vac the passage afterwards.

odds are it would be ok..but you would think (worry) about it for a long time. so for piece of mind and a better way. take it off .you already said that a 3/8th's nipple fit fine in the block, so check out the threads on the pickup.run a die on the threads, and put it back together.. it will be worth it just to have your piece of mind.. and your oil pump will thank you for it..

If you get good thread engagement with a pipe nipple, I'd bet that the pickup tube is the problem.
If you hog out the threads bigger, what happens down the road if you change pan and pickup? If you have to cut the block a bunch to fit this pickup, then you might actually go so far on another (correctly sized) one that you get to the end of the threads.
And it's easier to clean than the block of an assembled engine.

I'm betting it's that zinc coating which makes it extra tight. the reason I suggested a die was for ease of cleaning after.

I agree 100%. |
