Most guys don't break 14 unless they're FI or on the bottle.

This is for my Honda Pilot, not my TL. I am just looking at the worse case scenario and haven't dropped the pan or looked at anything internally yet.

There is a type s 3.5 block for sale on eBay going for $100. Missing one piston though. Need spares?

I know you're talking about your Pilot. I have an '03 MDX and I'd be heart broken if she started to ping / knock. It would be cheaper to get the heads machined & rebuild the piston/s. I would scope the piston heads and look for signs of knock. Autozone might be able to do it but you need to pull the plugs. You could buy a borescope at Harbor Freight for $50 and check it out yourself, the rears will be a PITA especially since the $50 scope is only two feet long, you could spend another $50 and get video feed scope instead. If the low end knock dissipates after you have it running for a while then it might be piston slap. I hope things don't deteriorate in your situation. If anything.. a rebuild will probably be cheaper, especially if you DIY and find reputable shops to work with you on it.

Thanks. I don't think it's detonation. It is worse when cold, but the weird thing that I start the engine and it sounds fine. But when I gas it in park, the knocking immediately comes on. Then it sounds like a damn diesel. As it warms up it does quiet down, but it is always there.

I can't pinpoint exactly where it's coming from yet but it seems like it's piston slap. The performance is still good but the noise just drives me crazy.
