Been searching for the last 15 minutes and not sure I have a definitive answer. I'm trying to chase an oil leak that is coming from high up on the engine near the oil filter.
Does anyone know what sensor this is, just above the trailing spark plug? Does that look like a stock sender unit (it feels a little flimsy)?
Yea, knock sensor. Your leak may be coming from the oil fill neck or the pedestal the oil filter sits on. There's 2 small o rings under there. Other than the oil line under the filter, there's no other oil sources in that area
