An interesting thing about the house analogy is that a house just sits there while a car goes speeding and bouncing down the road, bumping (or crashing) into things and just keeps on going for years. Houses and cars will always eventually need repairs with age and wear. Speaking of age and wear, if you haven’t had your timing belt replaced, you are overdue for this important maintenance item. Failure to replace your timing belt at specified intervals could lead to timing belt failure and catastrophic engine damage that will cost thousands to repair.
As for oblivion’s question about the rear main seal, it was pertinent to your post. I also did not know that the V6 in the Accord had main bearing caps with side bolts. Few engines do, so it’s uncommon to hear of this. All engines have a rear main seal that can leak with age and be difficult to pinpoint, hence the question and confusion. Please refrain from being crass and condescending towards those who are trying to help you. Some sites (and contributors) charge money via PayPal for answering questions like this. This site and these contributors do not, so be grateful.
