2011 Honda Pilot, J35 VCM with 123,xxx miles, Compliant.......A/C blowing warm air.

Went out to get the vehicle & upon start-up a loud rattle/knocking noise was coming from the engine. I immediately shut it down & checked the oil level....It was within operating range & fairly clean looking.
Left it where it was & called the customer to ask about the noise....."Yeah, That's been there for a while" crzy I asked if he would like that looked at? He said "Sure, I guess, But it runs fine"

Thought about it being a rocker arm, But the noise wasn't "In Time" with the valvetrain. My long screwdriver to the ear pinpointed it to the timing belt area. Tore the covers off & found what I thought was a collapsed tensioner.

Called the customer & quoted a timing belt kit, valve adjustment, & a A/C clutch relay, Customer declined the valve adjustment.


Turns out the tensioner was still sound hydraulically, But was worn down or the ram snapped off at the pin hole. Didn't find the tip of the ram anywhere. The tensioner pulley arm had quite a bit of wear as well. He's lucky it didn't jump time, I'm amazed he was more concerned about the A/C!

Luck. Some guys could drop a 3/8" bolt down the valve cover and it would bounce thru the engine landing perfectly into the bottom of oil pan damaging nothing. Me? I could drop a "micro-atom" in the valve cover and it would wipe out the entire engine.
He has the "luck".

If it were July or August, I would NOT be surprised that someone in Texas was more worried about the A/C than something not-A/C on their car.

But to do so in May when it hasnt even approached sweltering yet, yes, that’s a little strange.

Are most of the tensioners spring loaded or hydraulic / engine oil pressure ?

I got that tensioner in two Aisin T-belt and water pump kits in a row, for a 5VZ-FE. I think someone at Aisin wasn't qualified to assemble the kits.

Declined valve adjustment? My question is why does Honda make a utility daily driver engine that requires valve adjustments?

I am not amazed at all. I have a van in the shop with 9+ year old Firestone tires that are dry rotted and cracked. They want the AC fixed for their trip to AZ. I mentioned the tires and they are not concerned.

Well Chris … he was driving what is normally a modern quiet engine sounding like a 1939 tractor …
Nuff said.

With 123,000 on the clock I would have the valves adjusted too.

It starts and gets him from A to B. It works in his mind.

The AC is not blowing cold, so it does not work.

If only life were this simple, we would all be much happier!

Not everyone is a fan, but annual state mandated safety inspections have their place.

The longest lasting passenger car engines I'm familiar with (OM616/617 series Mercedes Diesels) require an adjustment every 15-20k miles.

The Honda requires it what? Once per timing belt swap at 100k?

Think something might have worn just slightly in 100k to justify checking it out and seeing if anything should be adjusted? Valves tighten as they wear. Self-adjusting hydraulic lifters do clog and stop working as well as they did originally.

Seems like sound practice regardless of manufacturer. I recall that our Toyota Previa (which was another super-long lasting and robust engine) had an optional valve adjustment as best practice once in a very long while.

Timing belts that routinely last past 100k arent a bad thing. Getting into the engine once every 100k isnt a bad thing. Looking at valves, which is super easy on a 4 cyl (which is most of what Honda makes) isnt a bad thing. And lest we go down the path of some superiority for chains, they do break, their tensioners and guides do fail, and a chain should be tested for wear in a process that aligns the cam and the crank, to look for number of degrees misalignment. That should be fixed by a new chain or at minimum, offset woodruff keys. The fact that nobody adheres to this as a general rule doesnt make them right.
