| Post subject: | Oil pump Pick up woes |
I can see some light at the end of the re-build tunnel, but I've come across one more snag. I needed to get a new pump screen and had one in the first couple of calls that I made, it's a Melling 66-S4 but when I went to screw it into the block it wouldn't even start. After I inspected the threads on the new tube it's clear that they aren't cut correctly as they are barely cut into the tube. So they got me another one...same way, and another. I had a plumber buddy run a 3/8 NPT die down to chase the threads and its goes in perfect now but the tube must be too long because it's in as far as it can go (pipe wrench) and it inteferes with the pan sitting on the block. Any suggestions, I put my old pick up back on to check the height and it seems too long also, but I know it was in there before, with this sdame pan. Any help would be appreciated. |

Deuce, I assume you are doing a truck and you have the pan with the sump in the front of the pan? WHen I redid my truck I obtained 3 or 4 pickups from forum members. Surprisingly to me the sumps were different lengths. In a consult with my favorite machine shop guys, they suggested I bring the sumps in and they had an old block in the trashpile, and we could study the problem with my pan. We used a ball of clay to see what the clearance would be with the longer sumps and when turning the sumps at different angles to the long axis of the block. SHort of it....it is amazingly easy to get the sump in backward, even looking at the picture in the FSM. If yours is really too long, heck just cut the tube and rethread. And Harbor Freight has an appropriated pipe threader on sale now, too, works fine for a one time thing! rock '64d100 |

No, it's actually going in a Dart, the original engine too. I remember the orientation of the pick up, it was parallel to the crankshaft, as is the one I'm installing. what's could be the deal with the original unit though, the pan doesn't really fit down with it in either. |

Maybe the female threads are buggered up a little. I think I'd try running a tap down it to clean it up |

My sons 72 Dart does not have the pick-up running parallel to the crankshaft. It runs perpendicular to the Crank. So does my 65 Valiant? That may be the issue? If you have the original pan and pick-up it almost has to be the way the pick-up is turned. Rick |

Not the tube, of course that is perpendicular to the crank. The actual pickup, the bottom is flat, parallel to the crank. |

| Post subject: | Pick-up? |
Sorry I misunderstood . But if nothing else has changed, ie you use the same pan and pick-up, then it seems like it should fit. Is it possible the pick-up tube was real tight in the block and got bent down while removing it ?? Just thinking out loud. Rick |
