2014 Patriot Sport fwd
I had to replace the oil pan on a 2014 2L fwd patriot sport due to a lack of intelligence from the oil change chain my daughter took it to. After replacing the pan I found a small o-ring on the flr. Inside.Diameter is approx 5/8". The pan is buttoned up and torqued. My question is anyone know what it might be? It is cracked like old but the jeep only has 55k miles. B4 I fill it tomorrow with fluid for leak test I would love to know if it is critical. I had plastic spread on the floor so it came from the engine compartment?
