I posted a few days about about stripping my drain plug. Well I dropped the oil pan today and I found a 4mm hex bolt in the bottem of my oil pan. The only thing I can think is the mechanic dropped it while doing my valves. He's the only one thats been inside the engine. Here are some pictures. Is it possible for a bolt to find its way to the bottem of the pan from the top of the engine? Is the black plastic piece the oil return? Could it of came down from there? Also if you notice the bolt looks like it has locktight on it.
