PVC valve replacement

[Flow Master]

How often are you guys changing this out. I know it's a maintenance item but do you do it at 30k or what. I need to change the heater tees also. I guess do them both at the same time. and same intervals?
Thanks,

PCV 100k or sooner depending on condition. It’s super cheap so not much harm doing it early. And the newer the engine the less often it is needed, since a tight engine will have less blow-by gasses to deal with.

Heater T’s.. some trucks will never need them. Mine are perfect at almost 200k. Others had them pop by 150k. So I wouldn’t assign them an interval, just pick a point that it’s good to get in there and inspect them.

I changed mine first at 130k. It was overdue. Still functioning but slow and had a lot of junk/obstruction. I think 100k should be first change. Then every 60k or sooner.

What are “Heater Tees”?

Never mind…I found the issue on my third & fourth searches…

Wanderlost Overland said that the Toyota-recommended interval for the 1GR PCV was 60k miles. Not sure where they got that number, but it's what I'm going with.

Just changed my PVC valve on my new to me 2009 LC with 219k. Glad I did, makes me think it was never replaced.

Positive Crankcase Ventilation is a good thing.

Anything to know before attempting to replace? I have 208k on my ‘10 and am certain mine has not been touched!

Be gentle with the foam and you may be able to keep it on. I managed to get just one tear but no separation. I can use the tear for access next time.
Other than that is a simple task. You do need a deep socket.

Replace that PCV valve

With 10 years and 95K on my LX decided car is a keeper, it is time to catch up on what I neglected over the years. From rust cleaning on frame welds, POR15, Boeshield T9 and fluid film inside the frame, all fluids, complete brake job with new OEM calipers painted red (for the extra 10mph in top...

Every 60-70k miles for me. It's so cheap and easy to replace. Why wait until it is actually having problems to replace it?

Is there an updated part number for 2016+? or is it still 12204-38010 still the correct one?

That is the correct and still current one for the 2008-2021 LX570 and 5.7L LC200.

I replaced mine at 80k. It was still working but it's so cheap and easy to replace so why not? Someone in another thread said it takes 10 minutes to replace. I think they must have had one hand tied behind their back because 3 minutes is plenty of time! Mine had some gunky buildup on it but still had a nice click when I shook it.
