2005 Verado 250 have a leak I think from the main cylinder between the trim cylinders. The dealer is a Certified Verado dealer and saying a oil seal but they have never seen this problem. Said they were going to have to tear down part of it to make sure. I had the oil changed by the same dealer and the first time I took it out I noticed the oil on my motor totter. Called the dealer and he said no big deal, but needless to say it got worse. Would to much oil from an oil change cause this? Any help would be appreciated. Serial number 1B120046
