I'm thinking that if you cracked another pickup, it must be stressed in some way, and my first thought is "the pan." Look for wear/ rub marks, etc. Keep in mind that skillions of B/RB Mopars ran for decades and I'm joking. I know you realize that
I don’t know about v8’s but for slant six motors the FSM specifies that the oil pick up is an interference fit to the oil pan floor. My assumption is that mopar v8 engines of the same era would have the same fit requirements for the oil pick up tube.If your oil pickup is sitting on the oil pan floor in any shape or form, as you tighten your pan it puts stress on the oil pump pickup tube.
The weakest part of the pickup tube is at the the threads where it screws into the oil pump. Thread area could have easily split open.
Bronze gear on a solid flat tappet cam?Good idea, thanks. That would be a stripped gear. I have a bronze gear drive. Hopefully that is not it.
I have external with swinging pick up but a pro-stock pan & run a solid flat tappetWell this is not good. I hooked up an analog gauge and tried with a drill but nothing at all. I tried to burp the oil filter by loosening it, nope. I then removed the pump and it looks good to me. No scratches at all and the O-rings are perfect. This pump is not that old. This is the second time I have lost oil pressure. Last time it was the pickup. Looks like I have to drop the pan and take a look at this pickup. I even made accommodations for the pickup to not seal on the floor of the pan. YET, there were no noises when it was running. The oil was off for maybe 15 seconds or less at most. Only the time to pull up the driveway. 70 feet or so. It might have been ok until idle dropped to 950 idle speed.
Has anyone gone to an external pickup for the oil pump and used a milodon pro touring pan??
Solid flat tappet lifters
Check that, a Pinned HD gear Steel not bronzeBronze gear on a solid flat tappet cam?
I'm not sure that's recommended, I could be wrong but it's not the same billet as the solid roller cam.
My builder told me don't get a bronze gear.
Not sure where it came fromLet me guess: chineseium pickup tube?
Correct. It is also the same for V8s. The pickup is designed to rest on the bottom of the pan.I don’t know about v8’s but for slant six motors the FSM specifies that the oil pick up is an interference fit to the oil pan floor. My assumption is that mopar v8 engines of the same era would have the same fit requirements for the oil pick up tube.
My ‘engineering’ guess for the interference requirement is so the oil pick up tube is locked in place at both ends. If the tube that is deepest in the pan was allowed to dangle, there is a good probability that at some rpm it would vibrate harmonically and that would surely crack the tube at the fixed end.
Oh wow. Well two good things. One, you found it. Two, it doesn't sound like the engine ran long enough to get hurt.
You really don't need that fancy pan and pickup.
