Can a loose drain plug cause an oil leak?

A drain plug is used to remove oil from the engine. This threaded plug uses a sealing washer which tightens flush against the oil pan and the plug. If the drain plug is loose or the sealing washer is missing or worn it can cause an oil leak. Check to see if oil is dripping from the plug and then check its tightness.

Where does the oil go in an overhead cam engine?

Engines with an overhead cam design have pressurized oil ports in the engine block that supply oil to the camshaft and lifters. The head gasket is responsible for sealing oil pressure between the engine block and the cylinder head.

What causes oil to seep out of head gasket?

A leak in the head gasket will allow coolant to seep into the oil of the vehicle, but coolant and oil are different consistencies so they will naturally separate. Light swirls in the oil are likely caused by coolant. If there is enough coolant to make out the color, coolant is usually green, orange or pink.

Where is the oil leak valve cover located?

Valve Cover Leak Valve covers are used to encapsulate the valve train and control oil leakage. This cover is used in conjunction with a gasket which is located between the cover and the cylinder head. Due to engine heat when this gasket ages it can become brittle and crack allowing oil to leak.

Diagnosing a Head Gasket Leak Check under the oil filler cap. When a head gasket begins to leak, a common symptom that will arise is “mayonnaise” under the oil filler cap.
