I have a 2005 Pilot EXL with 128,000 miles. On my last dealer service visit the service writer said my Pilot's engine oil pan is starting to develop an oil leak and suggested removal and reseal; $591.80. I had been noticing for some time that when I park on my sloped driveway, a normal driveway slope, I can later see a small dime sized fluid spot where I parked but on a flat surface, like in the garage, there never is a spot. I check both my oil level and transmission level about twice a week and the level for both is always unchanged, no drop in level. Just to make sure I had the dealer tighten the bolts on the oil pan. I continue to get the fluid spot on the sloped driveway but not on a flat surface. Any ideas why this is happening? I really don't want to spend $600 to fix something that is of no consequence.
