Engine Air Filters

The 3.5 Tacoma and 5.7 Tundra use the same air filter element.

If it flows well enough for the big V8 any "restriction" of a quality OEM dry style filter shouldn't hamper the performance of the V6.

 

Hey all , is there a need to ever change your PCV valve out when you change your air filter?

Also what is everyone's thoughts on installing an oil catch can?

 

THAT right there.

 

The PCV (positive crankcase ventilation) valve is, generally, what most people treat as a "run to fail" component. Once they fail (clog up with carbon) however, this scenario may result in oil leaks because the crankcase has no way for the internal pressure to relieve. So there is a slight downside potential to that approach.

If I were you, I would remove yours and inspect it. Give it a spritz of brake cleaner followed by a spritz of spray lube. Shake it and blow through it. It is really nothing more than a simple one-way check valve. If that works for you, re-install and check it again yearly going forward.

Alternatively, buy a new one for $30 or so and slap it in there. And forget about it for the next 50k miles.

As far as catch cans go, I'm not an advocate. (Nor am necessarily against them). In my personal case, my Taco doesn't "burn" or consume any oil between oil changes. Like zero. None. Like not even 1 mm on the dipstick. So that leads me to believe the amount of oil vapors that would condense and be caught in a catch can would be infinitessimal. Just not worth it. Others may have different experiences and suggestions. One positive thing about a catch can, unlike some other dumb mods people make, is that it literally cannot cause any harm.

YMMV and I hope everyone has a great weekend. It is FRIDAY!

 

I did a catch can, mainly because I was bored and couldn't think of anything else to do to my truck at the time. It does trap some oil, a few ounces every 1k miles or so. Probably not enough to show on the dipstick, but not zero either. Will it make a difference? Probably not. But you probably don't need to change your PCV valve with every air filter change.

 

I just think that there's a TRD oiled air filter means that Toyota thinks it's OK for a while. I put in a K&N a few months ago.

In the Old Days they used oil bath air cleaners, paper air filters didn't exist, but those engines were worn out by 30k miles.

Just follow the maintenance intervals to what filter system you're using, and you'll be fine.

 

this is what i have

 

Change my air and cabin filters each April fools day for good measure. I hardly ever get them dirty.

 

the PCV valve is an important inexpensive part. at less than $20, i see no need to clean and re-use it. i would suggest changing it at the same time the spark plugs are changed, which according to toyota should be about every 60K miles.

i do not have any experience with a catch can and can't comment.
