Hi guys!!!
After changing oil and tuning my car from a dumb mechanic, after 2 days I went for tuning again from different mechanic because my cuore was missing... when he open spark plugs he found it was looking wet little bit.. he said that oil is coming in the engine.....
I want to know what are the causes of oil on spark plug?? I also changed my oil seal from my first mechanic because it was leaking... he said I kept your tappet lose because of Oil seal to make its position tightly....
Can any one tell me is this was the cause of oil coming to spark plug?? Also I didn't notice any decrease of engine oil though... My engine is still sealed and it also drops water from silencer....
Please help me out
P.S. Their is no sign of any white precipitate on spark plugs... It only looking wet and little black...
Can also it is one of the cause of petrol and CNG mixing? also tell me sign of weak engine..
Please reply soon
