Leak-Free Lubrication: Replacing Your Oil Pump Gasket
Those oil stains on your garage floor not only mean a mess you have to clean up—they also mean you have a worn-out oil pump gasket. Your vehicle is full of moving components that require constant lubrication in order to function properly. Ignoring a faulty oil pump gasket can lead to more troublesome (not to mention more expensive) problems than oil stains. Fortunately, replacing this gasket is a simple matter you can take care of yourself.
Difficulty Level: Easy
Here's what you'll need:
- Wrench and socket set
- Drain pan
- Gasket scraper
- New Oil pump gasket
- New oil pan gasket
- Engine oil
- Vehicle owner manual
CAUTION: Make sure your vehicle's engine has cooled over several hours before you begin.
Step 1: Place the drain pan directly under your engine's oil drain plug. Use your wrench and a socket to remove the oil drain plug so that the engine oil empties into the pan. Reinstall the drain plug.
Step 2: Slide underneath your vehicle and use your wrench and socket to remove the bolts fastening the oil pan to the underside of your engine block. Carefully pull out the oil pan.
Step 3: Remove the old oil pan gasket and discard it. If any gasket residue remains on either the oil pan or the engine block, scrape it off with the gasket scraper and then wipe clean with the rag.
Step 4: You should now see the pick-up arm protruding from the engine block. It will lead you to the oil pump. Use your wrench and socket to remove the two bolts securing the oil pump to the engine block.
Step 5: Extract the oil pump from your engine. You would be removing the pick-up arm in the process since it's attached to your oil pump.
Step 6: Remove the old oil pump gasket and discard it. If any gasket residue remains on the mating surfaces of the oil pan and your engine block, remove it with your gasket scraper.
Step 7: Place your new oil pump gasket on the mating surface of your oil pump. Make sure the holes on the gasket are directly aligned to your oil pump's mounting bolts.
Step 8:Re-install your oil pump (with the pick-up arm) by mounting it on your engine block using the same bolts you removed earlier. Tighten the bolts by hand first before securing a snug fit with your socket wrench.
Step 9: Put everything back together by following the reverse order of disassembly. We recommend replacing your old oil pan gasket with a new one.
Step 10: Pour in the new engine oil.
If you don't have enough space to work under your vehicle, you can use a floor jack and a set of jack stands to lift the front of your vehicle. This guide was written with a Ford 302 in mind. Refer to your owner manual for specific details that may require a different approach.
