How Does it Work?
An oil pan gasket forms a seal between the cylinder block and the oil pan when bolted in place
How Is It Made?
Oil pan gaskets may be a simple cork gasket shaped to conform to the engine block flange, a rubberized material, a molded rubber over a steel carrier or a full rubber molded seal Some gaskets are one-piece gaskets while others may be multiple pieces that require assembly during installation
Why Does It Fail?
- Engine heat
- Loose fasteners
- Sealing surface irregularities
- Over-tightened hold down bolts
- Excessive internal engine pressure
What are Symptoms of Failure?
- Oil leaking to the outside of engine
- Leaks on the floor
What Are the Consequences of Failure?
- Oil loss
- Smoking, potential for engine fire
- Engine damage due to low oil volume
