I have a 2012 pilot and have noticed a tick at idle, which made a valve adjustment come to mind. I don't believe one has been done, and the car is at 131k miles. Is there a method to check if it needs one? I have a leak-down tester so I figured I might do that before taking it in.

Mine started ticking a couple thousand before the 100,000 mile maintenance was due. Once Honda completed my 100k maintenance, the ticking was gone. I'm sure you know that over time the they loosen up.

A tick could be a leaking exhaust header on the head. It could be a loose valve. It could be poor oil quality. Or it could just be a tick. Watch out for Lyme Dz. LOL

It's been my understanding the valve lash get's tighter/smaller with miles, not looser, especially the exhaust valves. When the lash gets too tight, due to the seat receding, a burnt valve can occur. Tappy valves are happy valves, within spec of course.

That has been my understanding as well, that Honda engines tend toward tighter valve lash then looser.

Exhaust generally gets tighter, intake looser. Everyone seems to think only do it if you have an issue. What about the issues you don't notice? As the lash gets tighter eventually the valve is held slightly open, eventually burning it. To loose changes the effective camshaft profile, less lift, less duration, closing up the centerline. That changes the performance of your engine. I have never had anyone come back and say the valve adjustment didn't make positive improvements in their idle quality, performance, and/or mileage. Want the best reliability your veh. is capable of, maintain it.

When my Pilot began to develop a misfire, which triggered the check engine light, a valve clearance adjustment resolved it.
On my invoice, the tech noted that all of the exhaust valves were "extremely" tight and that half of the intake valves were tight.

Currently going through this saga.....#6 exhaust valve was toast. Assumingly from a lack of valve adjustments in 182,000 miles and probably got too tight. Good luck!

For those that had valve adjustment done, what did it cost?

Intakes get looser, exhaust get tighter as an engine rolls up the miles. If exhaust valves loose lash, they do not contact the seat hard enough and cool from the contact. Overheated valves soon fail to seal and you lose that cylinder

Thought that's what I said in response to post #2? See post #7, not all intakes get looser.

It is always amazing to me that people second guess factory maintenance requirements and ignore them. Think of it this way: if you are wrong you are risking damage to the second most expensive thing you own - typically a home will be the only thing that costs more. And if you are correct, why wou!d you do business with a company that is either dishonest at worst or incompetent at best? There is a reason a valve adjustment is recommended at 100k. Our Pilot has a little over 100k now. Valve adjustment was done last year with timing belt, tensioner, etc. Engine is smooth and quiet. Can barely hear it running when it is in the garage.

This is why I don't buy used cars anymore - the savings is eaten up in time and money fixing\rectifying other people's idiocy.

I just bought a one-owner '14 EX-L that was dealer maintained...those cars are out there.

In any case, I'm still putting on an S-VCM unit.
