If the oil is on the inside parts of the spark plug like the bottom insulator, that's a bigger issue, you have either leaking valve seals or very leaky piston rings. If your car blows a puff of blue smoke on startup, you probably ave leaky valve seals. If it blows blue smoke all the time, leaky piston rings.
Oil leaks are the most common symptom of a problem with the crankshaft seal. If the crankshaft seal dries out, cracks, or breaks, it can cause an oil leak. Small leaks can cause oil to accumulate on the undersides of the engine, while larger ones may produce a drip of oil from the front of the engine. The crankshaft seal is mounted behind the engineâs main crankshaft pulley, so servicing it requires the removal of the belts and crankshaft pulley and harmonic balancer before it can be accessed.
