The service manual says that the bottom of the pickup should contact the bottom of the oil pan. Anyone have any opinion on this? I know the design of the housing actually keeps the screen off the bottom, but I was still curious what other's opinions might be - thanks

NO
Need at least a quarter of an inch but less than a half inch clearance. If not flow will be restricted.

Small gap. You want to maximize oil flow while keeping the pickup low in the pan.

Have seen anything from 1/16 to nearly a half inch in performance app and not seen any problem in oil delivery or any starvation. That is why I said what I did, I don't like it anymore than a 1/4 either but touching is a no/no

Page 9-65 of the '69 service Manual.
Just wondering...I have mine set at about 1/4 - 3/8".

If you're talking about the factory style pickup there's no advantage to having a clearance under it, even with the pickup contacting the pan the channel that feeds the opening is larger than the opening so there is no restriction.

Aftermarket pickups like the Milodon must have clearance.

Years ago one of my friends believed that the pickup shouldn't touch the pan and hot bent it to get about 1/4" of clearance. About three years after this at the top of third gear, the pickup failed at the threaded end and he lost all oil pressure. Oh yeah, it was a '66 Hemi Coronet. IIRC there was just someone on Moparts that had the same thing happen, a crack at the pickup threads with the accompanying loss of oil pressure.

Without the pickup touching the pan it apparently can get into a resonance. This leads to metal fatigue at the threaded end with the eventual cracking failure. No, I'll continue putting BB's together with the pickup touching the pan.

John is right. The OEM pickup has a shield on the bottom that spaces the pickup properly and should touch the pan. Aftermarket pickups do not and need to be spaced up manually.


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

Absolutely not!! It should never touch the pan, UNLESS the pickup is the OEM syle mentioned above.
Two reasons why not: Dent the oil pan at the pickup, restricted flow of oil in pump and motor. Two, break something inside the motor, the oil flow is again, restricted at the pickup.

Correct. Factory style can touch. Plenty of area for the oil to access the tube.

If it is aftermarket, not only should you have clearance, but add a positive spacer between the PU and pan to make sure that the pan does not get sucked up to the PU.

and a spacer would take of the resonance problem possibly causing a crack on down the line
