I just got my '05 EX-V6 last night. As you can see from my Sig I have a long line of Hondas.

If I'm not mistaken, my 2001 EX-V6 did not have a valve adjustment. Hyd. lifters? My 05 does have it in the maintenance.

Now the real kicker. I don't see Timing belt replacement on the 4-cyl. Did they change to a chain?

Owner's manuals leave a lot to be desired.

 

As I know VTEC engines don't have Hyd. lifters.

 

The K-series ('03+) 4-cyl. has a timing chain instead of a belt.

 

Hmmmm....maybe I should be checking those valves in my '01 V6. No ticking. 126k on it.

 

Damn, wish they had done that with the V6. That belt replacement is a killer. At least my sons new LX will have the chain.

 

Chain has to be replaced too at some points. does anybody know what is intervals for chain replacement? Broken chain destroys a lot outside of engine.

 

Having had a couple cars with chains, they should make a horrible noisy racket long before they come apart. We kept our '89 Saab for 220k miles & the chain tension adjuster showed that it still had a long long way to go.

Why would a broken chain destroy anything outside the engine? The timing cover is normally not plastic...

 

I heard that broken chain can break even a metal timing cover.
It may get jammed around crank pulley and because of a high velocity it may crack something else on its way out of timing cover. Low chances of course but you are right that before it brakes it gets loud.
What I wanted to say that if it is a chain it shouldn’t be left unattended at all.

 

I have had GM timing chains (Buick 3800 series 1) go for 180K without any noise etc. I have had Buick 3100s be running fine but feel like a brand new engine when a timing chain was replaced, and i hav had a ford explorer SOHC timing chain go bad on me TWICE in 100,000 miles.

With this being honda's first go at it measured against Honda's known reliability...anyones guess... I wouldnt want the first year of it as they seem to improve things along the way AKA v6 auto trannys were not up to honda's typical snuff...

However that said i dont think that timing chain engines are EVER set up as interferring engines meaning if the engine's chain breaks you will be fine unlike belt engines. Carbon deposits can lower the clearences and make an non interferrer and interferrer but that has been my experience.

I have an 03 4Cyl 68K. Now that I understand that it has a timing chain and not a timing belt, what is the function of the serpentine belt (that looks like a timing belt)? Is it important that that one be changed?
