Oil Pan Dipstick Mount Repair
Is there some sort of repair for the dipstick mounting fixture that's riveted to the oil pans??
I'm looking for feedback only, not actually a way to do the repair. I'm asking because we have a 100% method for a fix leaving the OEM bracket in place (after the fix). It would attach to the pan with some 1/4-28 pan head cap screws and be removable at later time WITHOUT the pan's removal! This would allow for a gasket change if ever needed. The only single drawback is it will require welding it to the inside of the pan, this means obviously the pan has to on the bench. Thanks, Gary in N.Y. P.S. If anyone is interested in the fix (assuming we do go forward with it) we will have a few ready in a couple weeks. It will come with a pre-drilled/tapped "plate", a gasket, and the attaching screws. I have photos of the setup but can't upload them at the moment! Will do in the near future.

Does this involve the supply of a replacement boss for dipstick tube to screw into? I have an engine at present which has worn thread in the boss as well as loose securing rivets. Plan on removing oil pan for a permanent repair as engine is on a stand. Interested for sure. The tapped plate will be required to be welded on inside of oil pan? Yes. Phil NZ. |

Re: Oil Pan Dipstick Mount Repair
I did mine with a 10/32 threaded plate, tack welded to the inside of the pan. But to fix without welding or pan removal--
What I would consider is using 10/32 or 10/24 Rivnuts with the appropriate gasket to allow for the thickness of the Rivnut. Drawback--The installer would need a tool to set the nut in the sheet metal pan

Re: Oil Pan Dipstick Mount Repair
i brought this up again to show a few shots of what actually happens after 60 or so years to the pan and the OEM gaskets, they are very brittle when opened up. Most have a number of cracks in the gaskets.
When we figured out how to make the actual bracket for inside the pan we felt more comfortable having it fully support the outer dipstick bracket. Plus we wanted to weld it a bit further away from where the gasket rests so there wouldn't be any distortion in that area! Thanks, Gary in N.Y. P.S. Here's a few shots, showing the entire process.

Re: Oil Pan Dipstick Mount Repair
Looks like it will do the job, but good grief, what's all the weld for?

To hold the bottom plate permanently in correct position relative to the outer dip stick holder.

Oil Pan Dipstick Mount Repair
This is the kit we sell for this. I always use loctite on the threads. Has the appearance of being riveted like original. I don’t see the need in having to replace that gasket often.

Re: Oil Pan Dipstick Mount Repair
That´s the way i do it to...looks nice an only need to change it is when restoring the pan.
I just peen it a bit backing it with a piece of copper to avoid damaging the head. |

Re: Oil Pan Dipstick Mount Repair
I’ll buy one of those kits Gary, whenever they’re ready for prime time.

Re: Oil Pan Dipstick Mount Repair
Oh my goodness! Looks to me like the welding holds the bracket inside the pan PERMANENTLY (like in forever) in position so that the screws can be removed and replaced without the internal bracket falling into the oil pan. Seems like a good idea to me as you don't have to worry about any nuts or rivets coming loose. Locktite is your friend. |

When we begin to make these available the amount of welding would be up to the welder, simple. It doesn't take much to keep the plate in position. Thanks, Gary in N.Y. P.S. To Joe above, I don't believe there will be any clearance issues with the internals but it will get checked. Your pan will be done identical to the one in the photo above! My friend has your pan for the straps also, however he will be gone for a few weeks?

Those 2 short MIG weld beads on the outside of the "V" plate are not a lot of welding, IMO. Much better than just a wimpy tack weld. Better safe than sorry. |

Re: Oil Pan Dipstick Mount Repair
Hi Joe, below here's a shot of how your dipstick adapter will end up being fastened to the pan!
When we tested it for leaks the only issue was a slight leak from the bolt threads showing up as a drip from under the bolt heads. We resolved it by lightly "spotfacing" the adapter and using very small copper washers under the bolts. Using sealer on the bolt threads would accomplish the same result but we wanted no leaks without any sealer in play! Looks like a done-deal! Thanks, Gary in N.Y. P.S. Got the Navarro's today, not exactly my choice for high-quality heads but "it is what it is". We'll deal with them and make them work, I'll call you on the weekend and explain! Have some pictures for you.

Curious what you found wrong or not optimal with the Navarro heads? I bought a set from Barney directly in '92 and have been holding them to use on my father's '32 Tudor sedan. I'd love to hear your thoughts on them |

Re: Oil Pan Dipstick Mount Repair
Been seeking a replacement dipstick tube boss. Seems like all suppliers are presently out of stock? Any suggestions as my one is worn in the internal thread.

Never tried to fix one but looks doable?? When we dropped Joe's pan by my friend the welder he tried to talk me into letting him make an entirely new 1-pc adapter from steel and weld it straight to the pan. Guarantying absolutely no chance of a leak and no fasteners OR gaskets needed any longer! I told him I didn't feel we needed to go that far, he claimed it would be real easy for him to do and still not that expensive! Thanks, Gary in N.Y. P.S. Hi Tim, with respect to the Navarro's, can't say about any of the older castings but these new ones definitely could have used much more care during the final machining! The ones I have here are not really what I expected to see with today's improved machining and casting techniques! I'll have more info on them a bit later in the month, will start a separate post!!

Thank you! I'd be interested to hear what you found. I've heard the same about the new Navarro intakes. |

Re: Oil Pan Dipstick Mount Repair
Drilled rivet heads off on an off-topic flathead. Punched rivet remains into pan. Slathered mount in silicone. Sheet-metal screwed it back on. 8^) Jack E/NJ
