Quick PCV hose and TB question

[Safado]

In the middle of a minor tear down and noticed it was harder than a rock and had a mild split on it. Just wondering what type of hose it should be replaced with and if the clamps are necessary to provide true vaccum. After reading the FSM mine has obviously been modified and has an L joint in it to make the transition easier. I was just noticing that there's quite a bit of play on the joints.

Also, when you take the TB off to clean it, should you also clean out the air intake chamber? If so, any recommended methods or precautions?

Thanks

3M throttle body cleaner works well and is sensor safe.

right...so that's what I've read to use on the TB itself...do you also use it on the air intake chamber? Any precautions about it going down the chambers?
Thanks

i got the replacement hose from toyota just a couple bucks, the tb cleaner will not hurt anything in that area

Thanks again...I'd kinda like to just run and pick something up locally if it's not that big of a deal, but I'll ping you if it ends up being impossible to find. Yours for the 3FE or will it work on later model 80s?

Anyone know on the clamps?

Feed your 80 a steady diet of Redline fuel additive per recommended dosages and it will clean-up the TB, upper motor, and O2 sensors spic and span. Mine has been getting the prescribed amount for 2 years now. I removed the TB (doin some pm) after using Redline for about a year and you could practically cook food and eat on the inside of the TB/intake it was so clean. Also, I was gettting annoying O2 sensor codes frequently. Have not set a O2 code since running the first bottle thru it...

i ended up getting one for the fzj cause the dealer had a hard time getting toyota to send the right one, i just cut to fit, i reused the old spring clamps

Fuel additive will only go through the fuel system. It doesn't go through the TB or intake. It goes straight to the injectors.
