How to find oil leak?

If u noticing a puddle on floor it could be from valve cover gasket, oil drain plug, oil filter, oil sending unit or timing chain cover. Clean the engine and see if u can trace the leak where it's coming from.

If no puddle on floor, the engine is burning the oil.

clean things up , I use a purple degreaser , it doesn't stink like engine bright stuff , compressed air with a rag to catch the mess , then you can start it and look for the source of the leak , I snugged up the oil pan bolts on my 2004 honda and that helped quite a bit
