Hey guys...2017 RDX with 49k km, during my last scheduled maintenance visit at the local Acura dealership I was recommended to replace PCV valve due to clogging. Estimated cost is around $400 (cad) at the dealership for a part that cost $45 (cad). I read few posts on this site but I couldn't find any relevant posts about replacing it due to a clogged valve. I spoke to a Honda dealer technician and was told I won't need to change the PCV valve on Acura cars. I'm not much of an expert on this topic so seeking your guys opinion. Should I cave in at the dealership or buy the part and repair it at a local shop or leave it and see what happens?

Thanks,
Dan

agreed!! PCV is covered under emission warranty, but does that apply to clogged valve or just faulty products? Worse case scenario, will have to drive across the border for it

 

Don't believe everything a dealer recommends. Follow the maintenance schedule that's in the manual as per the maintenance minder. If something goes wrong with the emissions system, check engine light will inform you.

 

You rarely need to change the PCV. My 06 Toyota Sienna has 190k miles on it now. It is still the original one. No need to change it if you don't suffer any gas efficiency loss.

 

So that works out to 3 hours of labour to replace it. Amazing and exactly why I have no use for the trades, be it a car shop, HVAC, plumbing, electrical, etc. Do it all myself and to a far higher level.

 

I changed my PCV valve (2013 RDX with 60,000 miles) for the first time yesterday. It took me all of 15 minutes because I'm slow. No problem removing the old one - I just turned it a little with my fingers to get it moving and slid a small screwdriver under the flange to pry it free. It slid right out and did not break. After examining, I'm not sure why this it's even called a "valve." It doesn't appear to have any moving parts - it's just a plastic tube with O-rings. My old one was not clogged, just oily (of course). Maybe the two O-rings could get hard and leak in high mileage cases but it looks like it would be easy to recondition by just cleaning the passages with solvent if they were clogged and replacing the two O-rings (if you could find them).

 

Googling found this:

the valve is INTERNAL

 

You're right. I ran a wire into the small end and there seems to be an internal spring that allows gas to flow, I assume from the crankcase into the intake manifold, There was no rattle in the new one or the old one,

 

If your 2017 is anything like my 2015 , it's as easy as the below vid

PCV being a pressure control valve when gets clogged up with gunk and fails to function properly causes the pressure to rise inside the engine block and eventually resulting in oil leaks from the valve cover. I'm glad that changing in in RDX is so simple because it was a complete PITA on my former VW Passat. After seeing this post, I definitely will go ahead and put in a new one. It's an excellent preventive maintenance.

 

PCV is an acronym for Positive Crankcase Ventilation; that's why the term 'PCV valve' makes sense.

I changed the PCV valve in my 04 Honda with the V6 3 liter engine once, looking to resolve a problem; it didn't resolve it, but it wasn't too hard to do. In any case, it is not a regular maintenance item because it doesn't fail often. That said, like changing oil at 3000 miles, it isn't necessary but doesn't hurt the engine to replace it.

My oil usage has been 0 up until 55,000 miles and just before the oil change it was off just a small amount. I changed the oil along with a new PCV valve and it's been right as rain ever since. I'm getting ready to change out the timing belt and water pump
so at 100,000 miles a new valve will be added to the work. The old one was a bit gunked up , so I'm figuring every 50k miles a new one is needed.
