2017 Ford F150 Oil Pan Replacement – Stop The Leaks And Upgrade
The 2017 Ford F150 often suffers from oil leaks due to its original plastic composite oil pan. This guide explains how to perform a permanent fix by replacing the leaking unit with an upgraded metal version or a fresh seal.
If you have noticed dark oil spots on your garage floor, a 2017 ford f150 oil pan replacement might be in your near future. Many owners of the 2.7L and 3.5L EcoBoost engines find that the factory plastic pans eventually warp and leak. This is a frustrating issue, but with the right tools and a bit of patience, you can resolve it in your own driveway.
You want your truck to be reliable whether you are commuting to work or heading out for a weekend of off-roading. A leaking pan is more than just a mess; it can lead to low oil levels that threaten your engine’s health. In this article, I will walk you through the entire process, from choosing the right parts to the critical curing time for the sealant.
By following these steps, you will save hundreds of dollars in dealership labor costs. We will cover the specific nuances of the 2017 model year, including how to handle the crossmember and the 10-speed transmission clearance. Let’s get your F150 bone-dry and back on the road.
Understanding the Plastic Pan Issue in the 2017 F150
Ford introduced plastic composite oil pans on several engines to reduce weight and manufacturing costs. While these pans work well in theory, the constant heat cycles of a turbocharged engine can cause the plastic to expand and contract. Over time, the pressed-in gasket or the plastic flange itself fails, leading to persistent leaks.
For many owners, the first 2017 ford f150 oil pan replacement happens under warranty. However, if your truck is past that point, you have a choice to make. You can install another plastic pan, or you can look into the metal pan conversion kits now available in the aftermarket.
The 2.7L EcoBoost is particularly notorious for this issue. Ford has released several Technical Service Bulletins (TSBs) regarding this problem. The most important takeaway from these bulletins is that the cleaning process and the sealant curing time are the two most critical factors in a successful repair.
Essential Tools and Parts for a 2017 ford f150 oil pan replacement
Before you crawl under the truck, you need to have everything staged. There is nothing worse than having a disassembled engine and realizing you are missing a specific socket. This job requires a mix of standard hand tools and some specialized cleaning supplies.
Required Parts
- Replacement Oil Pan: Choose between the OEM plastic (if you want to keep it stock) or a high-quality metal aftermarket upgrade.
- Motorcraft TA-31 RTV Sealant: This is the specific silicone Ford recommends. Do not substitute this with generic “black RTV” if you want the seal to last.
- Engine Oil and Filter: Since you are draining the oil anyway, this is the perfect time for a fresh synthetic blend or full synthetic oil change.
- New Drain Plug: If you are sticking with the plastic pan, these plugs are often one-time use or have seals that wear out.
Recommended Tools
- 1/4-inch and 3/8-inch Drive Ratchets: You will need various extensions to reach the bolts hidden behind the crossmember.
- 8mm, 10mm, and 13mm Sockets: These are the primary sizes for the pan bolts and skid plates.
- Torque Wrench: You must tighten the pan bolts to the exact inch-pound specification to avoid cracking the new pan or stripping the block.
- Plastic Scrapers: Never use a metal scraper on an aluminum engine block, as it can create gouges that lead to permanent leaks.
- Brake Cleaner: You will need several cans to ensure the mounting surface is 100% free of oil residue.
Safety and Vehicle Preparation
Safety is the top priority when working under a heavy vehicle like the F150. Ensure the truck is parked on a level, flat surface. Engaging the parking brake and chalking the rear wheels is a non-negotiable first step for any DIY mechanic.
If your truck is lifted or has high ground clearance, you might be able to do this on the ground. However, using heavy-duty jack stands is highly recommended. Position the stands under the frame rails, not the suspension components, to ensure the vehicle is stable while you are tugging on stubborn bolts.
If you are an off-roader, your truck likely has skid plates protecting the undercarriage. You will need to remove the front and mid-plates to gain access to the oil pan. Keep these bolts organized, as they are often different lengths and sizes than the engine components.
Step-by-Step Guide to Removing the Old Pan
Start by placing a large drain pan under the oil plug. Remove the plug and let the oil drain completely. This can take a while, so give it at least 20 minutes to minimize the amount of oil that will drip on you once the pan comes off.
On some 2017 F150 models, the front crossmember or the stabilizer bar may partially block access to the front pan bolts. You may need to loosen the bolts on the stabilizer bar mounts to swing it out of the way. If you have the 10-speed transmission, be mindful of the cooling lines that run near the rear of the pan.
Locate all the small bolts around the perimeter of the pan. There are usually around 20 or more. Loosen them in a crisscross pattern to prevent the pan from hanging by a single bolt and potentially bending or cracking. Once the bolts are out, the pan might still be stuck due to the old RTV sealant.
Gently pry the pan away from the block using a plastic pry tool. Do not force a screwdriver between the pan and the block. Once the seal breaks, be prepared for a small amount of residual oil to splash out. Carefully lower the pan and set it aside.
The Critical Cleaning and Surface Prep Phase
This is where most DIY 2017 ford f150 oil pan replacement jobs fail. If there is even a microscopic film of oil on the engine block, the new RTV will not bond correctly. You must be meticulous during this stage of the process.
Use your plastic scraper to remove every trace of the old sealant from the engine block. Take your time. Once the bulk of the material is gone, soak a lint-free rag in high-quality brake cleaner and wipe the entire mounting surface. Repeat this until the rag comes away perfectly clean.
Wait for the oil to stop dripping from the upper engine components. If oil drips onto your freshly cleaned surface, you must clean it again. Some technicians suggest letting the truck sit overnight at this stage to ensure all the “nuisance drips” have finished, especially if you are working on the EcoBoost engines.
Installing the New Pan: RTV Application and Torque
If you are using a new plastic pan, it may come with a gasket already installed. If you are using the metal upgrade or an RTV-only pan, apply a 1/8-inch (3mm) bead of Motorcraft TA-31 around the entire flange. Make sure to go around the inside of the bolt holes to ensure a continuous seal.
Carefully lift the pan into place. Try to go straight up so you don’t smear the RTV bead. Hand-tighten a few bolts on opposite corners to hold the pan in place. Then, install the remaining bolts until they are finger-tight.
Use your torque wrench to tighten the bolts in a sequence. Usually, this involves starting from the middle and working your way out to the ends. For the 2017 F150, the torque spec is typically very low—around 89 to 106 inch-pounds (not foot-pounds!). Check your specific engine’s service manual to confirm these numbers.
The 24-Hour Rule: Why Patience is Key
This is the most important piece of advice for a 2017 ford f150 oil pan replacement: do not add oil immediately. The RTV sealant needs time to “skin over” and then fully cure. Most experts recommend waiting a full 24 hours before filling the engine with oil.
If you add oil too soon, the pressure and the oil itself can push through the wet sealant, creating a pathway for a leak. If that happens, you have to start the entire job over from scratch. Use this downtime to reinstall your skid plates, change the oil filter, and clean up your tools.
After the 24-hour wait, fill the engine with the recommended amount of oil. Start the truck and let it idle while you inspect the perimeter of the pan with a flashlight. If everything looks dry, take a short test drive and check again once the engine is up to operating temperature.
Frequently Asked Questions About 2017 ford f150 oil pan replacement
How much does it cost to replace the oil pan on a 2017 F150?
If you do it yourself, the cost is typically between $150 and $300, depending on whether you buy a plastic or metal pan. At a dealership or independent shop, the price can range from $600 to $1,200 due to the intensive labor required to clean the surfaces properly.
Can I use a gasket instead of RTV sealant?
Most 2017 F150 engines were designed specifically for RTV or a pan with an integrated seal. Using a traditional paper or cork gasket where it wasn’t intended will almost certainly result in a leak. Always follow the manufacturer’s recommendation for sealing materials.
Is the metal oil pan upgrade worth the extra money?
Yes, especially if you plan on keeping the truck for several more years or if you do heavy towing or off-roading. Metal pans are less prone to warping from heat and are much more durable against debris hits on the trail.
Why does my 2.7L EcoBoost keep leaking even after replacement?
This is often due to “oil creep” during the installation. If the block wasn’t perfectly dry or if the RTV wasn’t allowed to cure for 24 hours, the seal will fail. Some technicians also recommend replacing the oil dipstick tube seal at the same time, as leaks there can mimic a pan leak.
Final Thoughts for the DIY Mechanic
Completing a 2017 ford f150 oil pan replacement is a rite of passage for many F150 owners. It is a job that requires more patience than raw mechanical skill. By taking the time to clean the surfaces perfectly and allowing the sealant to cure, you can achieve a professional-grade repair that lasts the life of the truck.
Remember to always double-check your torque specs and keep your work area clean. Once the job is done, you can drive with the peace of mind that your engine is protected and your driveway will stay clean. Stay safe, take your time, and enjoy the satisfaction of maintaining your own rig!
