As the 7.3L trucks get older, oil pan leaks get more and more common. One of the most frequent sources of oil pan leaks is from the factory dipstick adapter in the side of the oil pan. We've seen a number of interesting repairs on the stock dipstick adapter, most involving some sort of sealant like silicone...and some even involving epoxy type products like JBWeld. We've also seen the dipstick adapter nut over-tightened to the point of distorting the adapter inside the pan (in such a way that it would never seal again, even with a new o-ring).

Whether you've got an oil leak now, or you're building a new engine and don't want to deal with one in the future, this Dipstick Adapter Repair kit is the once and for all solution! This kit completely eliminates the stock dipstick adapter, replacing it with a new machined aluminum adapter that features a double o-ring seal on the OUTSIDE of the oil pan. This kit can be installed with the oil pan still on the engine, and the engine still in the truck. Best of all, if the o-rings in this kit should ever leak, this adapter can be quickly and easily removed and reinstalled with new o-rings...all from outside the oil pan!

Contents of the Strictly Diesel Dipstick Adapter Repair Kit:
  • Billet Aluminum Adapter (US Sourced T6061)
  • Machined Steel Backing Plate/Brace (1018 Cold Rolled Bar Stock)
  • ALL Machining and Assembly in US Facility by US Workers!
  • Stainless Steel Screws with Copper Sealing Washers
  • Double O-Ring Set for a Positive Seal
  • Installs Quickly Without Oil Pan or Engine Removal
  • Quickly and Easily Serviced If Necessary
  • Fits ALL Ford 7.3L Trucks, Excursions and Vans
  • Correct New Ford Dipstick Tube O-Ring
  • Detailed Full Color Installation Instructions.
  • Patented Design - US Patents : #9,285,259 & #9,671,272

Note: This product may require modification to fit engines using HYPERMAX connecting rods or using an AFTERMARKET Engine Girdle across the main caps. It has been used with both products, but clearances should be closely checked and installation may require additional steps.

T444E CUSTOMERS : This repair adapter has been used by a number of T444E owners with the same success as we have had on the Ford Powerstroke applications. To date, the only issue we have heard of was a school bus with a starter that was so large it interfered with the adapter, and that customer simply installed a smaller starter to solve the problem. To the best of our knowledge, this adapter should fit all T444E applications...but to be clear, we are not a Heavy Duty shop and we don't work on that engine. There are no T444E vehicles in the selector above, so if you are needing to order for that type of engine, simply click the "If you know your part number click here" link that is located below the Make/Model/Year selector.

Strictly Diesel Dipstick Repair Adapter Kit - FREQUENTLY ASKED QUESTIONS:

Q : Do I have to remove the engine and/or the oil pan to install this part?
A : No, this Dipstick Adapter installs from the OUTSIDE of the oil pan and does NOT require removal of the engine or the oil pan for installation or service.

Q : How do I get the factory part out of the oil pan when installing this Dipstick Adapter Repair Kit?
A : You don't. The interior portion of the factory dipstick adapter stays in the oil pan. During the installation, after removing the original o-ring (so it doesn't get stuck in the oil pickup and reduce oil flow), this part is dropped into the lowest part of the oil pan sump, where it will remain until such time as the engine and oil pan are removed.

Q : Can the factory part that is left in the oil pan cause any engine damage?
A : No. The factory dipstick adapter will sink to the bottom of the pan and have nowhere to go. It is too large to enter the oil pickup tube and there is nothing else in the bottom of the oil pan for it to interfere with. The only possibility for any issues with regard to the part in the bottom of the oil pan would be in the case of the engine being operated upside down (a situation that more than likely means that you've got bigger problems than whether the engine continues to run or not).

Q : How does the Dipstick Adapter Repair Kit work?
A : This Dipstick Adapter has a rear support brace that goes in through the opening of the oil pan and is swiveled into place during the installation. The 2 screws visible in the photograph above are used to retain that support brace and pull it tight against the interior wall of the oil pan, which compresses the 2 o-rings against the outside wall of the oil pan and creates the seal.

Q : Is there any drilling or modification to the oil pan required?
A : No, there is absolutely no modification to the factory oil pan required to install this Dipstick Adapter.

Q : Does this product include installation instructions?
A : Yes. If you've ever purchased or installed any of the other "Strictly Diesel" or "Driven Diesel" products, you've already seen the type of detailed instructions that we've become known for. This product is no different. We've taken the Dipstick Adapter and packaged it into a complete kit with a new Ford O-Ring and a set of Detailed Full Color Installation Instructions that show how to install the product into both an "OBS" (94-97) and "Super Duty" (99-03) style truck.

Easy to install. Watched the youtube video and knocked it out in about 2 hours. I've driven the truck for a few weeks with no more leaks.

My Dually had just turned 400,000 miles and started to leak a steady steam of oil from that o-ring. Thankfully these individuals save my azz! If the engine were to be pulled it would've been for a new motor and not for an O-ring repair with the mileage on it. The part has been in for about a month and I've been pulling loads and using my Diesel as it is intended for. Thanks again and GOD Bless!!!

Look. You have 2 choices. Pull your engine and seal the pan or use this adapter. I installed this in about an hour and that was with really good cleaning of the pan. Not a drip since. Strictly Diesel is a first class company.

After years of clean, rtv, sorta stopping the leak and repeat 6 months later it's great to finally have a permanent fix. Took me all of 20 minutes and I can park in the driveway without a drip pan for the first time. Great product and couldn't be easier to install.

Great product! I had purchased other companies dipstick adapter repair kits prior to this one. I had limited success the second to round. My truck leaked 8 quarts in an hour. This product solves the problem and prevented the leak. Fairly easy to install for a DIYer.

Had a leak, now i don't. This is the easiest solution that is for the more carefree low stakes at home mechanic. All the other solutions to this dipstick flange failure induced cringe worthy stress. Thank you strictly diesel for a quick painless solution.

OVERPRICED. It’s way too expensive for what it is. They don’t even offer lube before they bend you over. The product works as intended. Can’t complain about anything other than the price.

Have installed numerous times at my shop. Absolutely love it, other than the price no retailer discount whereas there's not any room for mark-up.

Quality, fit and function. Great product. This device solves what can be a very expensive problem. If you have the skill and tools to remove your trucks starter, you can install this part in your driveway.

Response:The instructions for this product are not posted online, but if you are capable and comfortable removing the starter from the truck, you should be more than capable of finishing the installation of this product. It is very simple to install.
