I'm almost at 75k miles on my TSX and I was thinking about a timing belt change and maybe all the other belts over there when I reach 80k. What do you guys think? I prefer to do maintenance soon rather than later.

Also, I read somewhere about replacing a PCV valve every few yrs or something, I don't think I've ever had this done. Should I and for what reason?

I believe the TSX is chain-driven (hence the comparatively noisy valve-train), no replacement typically scheduled.

I have read that somewhere but I read on hondanews.com something about the 07 tsx's maintenance minder system:
To eliminate unnecessary service stops while ensuring that the vehicle is properly maintained, the TSX now has a Maintenance Minder System that automatically monitors the vehicle's operating condition... The system, which can be reset manually by the owner, monitors all normal service parts and systems, including oil and filter, tire rotation, air-cleaner, automatic transmission fluid, spark plugs, timing belt, coolant, brake pads and more.To prevent driver distraction, maintenance alerts are presented when the ignition is first turned on, not while driving.

But lets assume there is a chain, when should I change all of the other belts?

2004 TSX Maintenance Schedule

Belt/chain replacement doesn't show up in the normal maintenance schedule. I believe the timing chain is due for replacement at 110K mi. which is when the drive belt will most likely be replaced (and the water pump too). If you like to do your maintenance early I guess you can replace your drive belt at 80K mi.

110k-120k get your money out of OEM imo.

The cam chain is designed to last the life of the engine. Where does this 110K miles come from?

I think hes talking about the timing belt in the TL that is replaced around that time.

If you're worried about all these expenses and your car is paid off, just sell or trade in the TSX and get a new car.

I don't recall where I read it. I guess the gist of my answer to the OP is to not worry about it yet.

I suppose the chain can stretch over time (and yes, they occasionally do break but it's very rare, much more so than belts, which break all the time comparatively speaking) to the point where the chain tensioner can't keep it within spec any more, at which point they would replace it.

But, I think this is one of those things that you take care of when you need to rather than preventively (at least certainly during the first 100K+ miles of ownership).

Honda started building bike motors with hydraulic cam chain adjusters back in the 80's. They were a little troublesome - Honda replaced both on one of my bikes (outside of warranty), but eventually they became reliable enough to not worry about. Remember, these are motors that are just starting to make power where the TSX redlines - 6000 rpm is in the lug zone for a modern sportbike motor.

If a cam chain breaks, you will definitely bend one or more valves and possibly even put a hole in the case. I guess it's theoretically possible to break a cam chain, but I've never heard of one.

My car isn't paid off yet but I was thinking about selling it soon but I think I want to wait for the new tsx next yr.

Thanks for all the replies guys.

I'm looking into doing the same thing possibly, but I won't be waiting for the new TSX though or an Acura for that matter.

I wouldn't worry about replacing the timing chain as it's not a servicable item as such and isn't replaced as part of any scheduled maintenance.It wouldn't hurt to replace the drive belt though.
