What can cause a hole in my oil pan?
The pan itself may leak if it sustains impact damage from an accident or road debris. This is far more likely if the oil pan is cast aluminum than if the oil pan is stamped steel. In such a scenario, the damage will usually create a hole or crack in the oil pan.
What causes an aluminum oil pan to crack?
Something leaped up from the road and struck this car’s surprisingly unprotected aluminum oil-pan causing it to develop a crack on the (relatively) flat surface on the bottom, causing much of the oil to drip out and intermittently bringing on the dreaded engine oil light.
Do you need to oval out a bolt to install an oil pan?
Start all the nuts or bolts and finger tighten. If using bolts, the pan may need a little rocking to get the pan and gasket holes lined up with the block holes. Worst-case scenario, especially with a non-brand pan, you may have to oval out a bolt to get the pan to fit in place.
What’s the thickness of an aluminum oil pan?
Every aluminum oil pan features 1/2″ inch thick rails and end seals milled from 6061 billet, then heliarc welded to .090-inch, 3003-alloy walls (except for marine pans, whose walls are fully .125-inch thick). Billet rails prevent warping and leaking after repeated on/off cycles, keeping the gaskets (and oil) in place after years of use.
Is it necessary to seal oil pan to engine block?
Engine builders, therefore, sometimes go to extreme measures to seal the pan to the engine block. That really isn’t necessary today. Advancements in gasket materials and design, along with proper preparation and installation procedures, can all but guarantee a clean bottom end.
What are the oil pans for a big block engine?
We have oil pans for street and competition applications. Oil pans are sold without dipsticks or other hardware unless otherwise noted.

Which is the best thread to repair oil pan drain bolts?
The helicoil is a hardened steel thread insert that comes in many different sizes and thread pitch. Repair with a helicoil is strong and permanent. I have used helicoils to repair head bolts without regret. The third and best option for repairing oil pan drain bolt threads is to use a drain bolt repair kit made by TIME-SERT.
How much does it cost to replace an aluminum oil pan?
The cost of replacing an aluminum oil pan can easily exceed $500 for parts and labor. You need to remove the sub-frame on some vehicles to remove the oil pan and that alone can get costly. Using a Time-Sert repair kit will take about 30 minutes from start to finish with professional results.
