Pcv valve replacement interval?

How often are you guys changing out your pcv valves ? I have a 2023 tacoma 2gr-fks and doing my oil every 3k miles.

 

They are lifetime, just remove it and clean it with carbclean/intake clean. Do the shake and reinstall. I usually see them need to be cleaned around 10 years.

The V6's aren't know for blow by issues.

Also I'd suggest 5k for intervals, its synthetic oil and designed for 10k. You don't get the most out of it until later in the run. It's a cam of worms but my 2 cents. Factory tech for Toyota.

 

How about timing cover leaks on the 2023 models? Anyway to prevent it?

 

no

 

Has yours leaked?

 

It's random but we havent seen many leak after the 2019 years. They still happen but its not as common as it seems.

 

no

 

Thanks. From how I understand it if they are gonna leak it happens within the first 2k miles or so

 

i thought i saw more in the 60-70k mile range

 

I think that is by the time people notice it leaking

 

I owned 4.7 tundra for nearly 300k miles and 19 years....never changed the pcv....wouldn't even know where to look for it. I only used mobil1 5w30 motor oil.

 

Not usually.

60k-100k is the usual time frame.

 

You don't necessarily need to replace it, but you should periodically check and clean it. My schedule this every 50k miles or so in all my vehicles. If they get plugged up at all, the engine will develop oil leaks.

 

Almost makes you wonder if 60% of oil leaks in older engines is due to a partially clogged pcv valve. Feel like it’s something that gets over looked or never even thought about

 

On older engines with a lot of crankcase blowby, it can overwhelm even a good PCV system and create leaks regardless. I have a 96 Camry with 230K that falls into that category.

 

regarding timing chain cover leak. i think one reason is the timing cover is made up of layers not just one cover. thus once all installed and run for a day or two no way to re check the torque and re tighten since a lot of the bolts are buried and can't be checked. IMO

 

I pulled mine at 150k miles. It still rattled just fine. I blew carb cleaner and compressed air through it. I put it back without replacement.

 

Pretty cheap to not change it early.

 

@Bishop84 I assume the same is true for the 2TR PCV valve?

 

Yes
