When an oil pan is cracked, dented into the oil pickup, or has drain threads too damaged to repair, Route 66 Auto Repair in Upland replaces it. First we check whether a thread repair or a new gasket would solve the problem for less, because a new pan is not always needed. If it is, the written estimate lists the pan, the gasket or sealant, oil, filter and the labor to reach it.
How do oil pans get damaged?
- Scraping a steep driveway or a parking block
- Freeway debris striking a low aluminum pan
- Driving over a curb or a rock on a dirt road
- Drain threads stripped by an overtightened plug
- Rust-through on older steel pans
- Cracks at the mounting ears of cast aluminum pans
Should the pan be repaired or replaced?
Stripped drain threads can often be fixed with a thread insert or an oversize plug, which our oil drain plug replacement page explains. A shallow dent in a steel pan that stays clear of the pickup can sometimes be left alone. Cracks in aluminum, deep dents near the pickup and holes are replacement jobs. Patching a pan in place is not something we recommend on a daily driver.
A crushed pan can press against the oil pickup tube and choke oil flow. If you hit something hard and the oil light came on, do not restart the engine. Have it towed; we accept tow-ins.
What do we check while the pan is off?
With the pan down, the technician looks at the oil pickup screen for debris, sludge or bits of old gasket, and at the bottom of the old pan for metal. Heavy sludge or bearing material changes the conversation, and we stop and call you before going further. Photos of the damaged pan and anything we find go with your estimate. If the oil light came on after the impact, we also test pressure as described on oil pump repair.
Our oil pan replacement process
Step 1: Assess the damage
We inspect the pan, the drain threads and the area around the impact, and photograph it.
Step 2: Estimate and approve
You get a written estimate covering the pan and the access work.
Step 3: Remove and inspect
The old pan comes off, and we check the pickup, baffle and pan bottom for debris.
Step 4: Install the new pan
The new pan is sealed the factory way and torqued in sequence.
Step 5: Fill and road-test
Fresh oil and filter, pressure confirmed at startup, a road test, then a leak recheck.

How pricing works
The pan itself and the access labor drive the price. On some engines the pan includes the baffle and an oil level sensor mount, and those cost more. If the pickup tube or its O-ring also needs replacing, it appears as its own line. AAA members get 10% off parts and labor, up to $75, with the card at the time of service. For damage that turns out to be just a leaking seam, see oil pan gasket replacement. Call (909) 608-7699 for a range.
Frequently asked questions
I hit something and now there is oil everywhere. What should I do?
Turn the engine off and do not drive it. An engine can lose its oil fast through a cracked pan. Call us, arrange a tow, and we will inspect the pan and anything else the impact touched.
Can a pan be patched with epoxy?
A patch might hold for a short trip, but heat cycles and vibration tend to break it loose. We treat patches as a get-home measure only and recommend a proper replacement.
Will you check the rest of the underbody?
Yes. An impact hard enough to crack a pan can also hit a transmission line, a heat shield or a steering part. We look and note anything we find, marked need-now or need-later.
