Engine oil pan replacement installs a new pan when the old one is cracked, crushed or has stripped drain threads. Driveway ramps, curbs and road debris on the 10 are common causes. Route 66 Auto Repair in Upland inspects more than the pan: a dent can push up into the oil pickup and starve the engine of oil. Our ASE-certified technicians photograph the damage, check the pickup clearance, and put every part on your written estimate before we start.
When does an oil pan need to be replaced?
- A crack or puncture after scraping a curb or speed bump
- A dent deep enough to reach the pickup tube inside
- Drain plug threads that are stripped or oversized from past repairs
- Rust holes on older steel pans
- An aluminum pan with a cracked mounting ear
Can an oil pan be repaired instead?
Sometimes. A stripped drain hole can often take a thread repair or oversize plug, which is covered in the oil pan hub pages under oil change services. A leaking gasket on a sound pan only needs a pan gasket reseal.
Replacement is the right call when the pan is cracked, badly dented, or has been patched before. On engines where the pan is part of the structure, such as many aluminum designs, a cracked pan affects rigidity too, so we do not recommend patching it.
Our oil pan replacement process
Step 1: Inspect and photograph
We document the damage and check for oil loss and warning lights.
Step 2: Drain and remove
Oil is drained and the pan is removed, with any crossmember or exhaust parts moved as needed.
Step 3: Check the pickup
The pickup tube and screen are inspected for crush damage or debris.
Step 4: Install the new pan
Surfaces are cleaned, the new gasket or sealer goes on, and bolts are torqued in order.
Step 5: Refill and verify
Fresh oil and filter go in, then we check oil pressure and look for leaks after a road test.

How pricing and timing work
Rear-drive trucks usually give easy access. Many front-drive cars and some all-wheel-drive models need the subframe lowered or the exhaust moved, which adds labor. Steel pans cost less than cast aluminum ones. Your written estimate lists the pan, gasket and labor. If the pickup is damaged, we stop and call before adding it. AAA members save 10% on parts and labor, up to $75. Call (909) 608-7699 for a look when the board allows.
After a new oil pan
Check under the car after a few days. Formed-in-place sealer needs time to cure, so avoid a same-day oil change elsewhere. Watch for low-clearance driveways and steep ramps, which are how most pans get damaged in the first place.
Frequently asked questions
Can I drive with a cracked oil pan?
Only if the leak is slow and you keep oil at the full mark. A fast leak can empty the pan in minutes. When in doubt, have it towed.
Why did the shop check my oil pickup?
A dent can push the pan into the pickup tube and block oil flow. That damage is invisible from outside, so we check it whenever the pan is off.
Is this the same as an oil pan gasket job?
No. A gasket job reuses the pan. Replacement is for a pan that is physically damaged. See oil pan gasket replacement if only the seal leaks.
