I do not mean to sound paronoid but you see, I have a 2004 Camry V6 and I love it. If the engine gets screwed I will be very angry. What if this guy put dirt or sand in the engine through the Oil fill? I have even heard he may crawl under, remove the oil filter, empty it and fill it with dirt/sand/metal shavings etc.. What would these types of materials do to my engine? Could your mechanic tell if dirt/sand/metal shavings had been put in the engine? I am not a car expert but it would be nice to know what to look for so I could catch it early and also nab the guy if he really pulls it off
