Change those vacuum hoses
In the process of changing the ECT sensor, I found the first split vacuum hose. As a precautionary measure I ordered a few to begin the swap out. Getting into it more today I found these under the clamps. You won't see them until the clamp is off other wise they appeared intact. There are likely plenty more brittle hoses to be found. So start checking your hoses for splits.
Just fixing these there is better brake pressure feel.

it would be nice if one of would publish a definitive listing of ALL of our vacuum hoses complete with location in the engine compartment and price
most are formed hoses, but some are just stock, cut to length hose
unfortunately the vacuum diagram under the hood is about as good as it gets on diagrams, the service manual is not what it could be when it comes to showing the accurate placement of the vacuum hoses!

The hose was in use at the PCV line and the crack occurred at the lower side of it. I could not notice it by my eyes but I barely could notice it by my ears.

Most rubber hoses under the hood have about a 10-12year service life, much less on high mileage cars.
Definitely a smart idea to catalog and replace hoses as part of routine maintenance now that our cars are getting older.
Maybe turn this thread into a catalogued parts and DIY tutorial?

I was looking at the Sewell site and that was what I'm going by for vacuum lines. Some of the generic ones are easily obtained through others sources. The ID usually is similar but there are some with an OD that is larger. Don't know why unless those particular lines generate more vacuum that requires a thicker wall thickness to be used.

Thread dig.
Pulling the hoses to trace back the P0302 or P0306 I found this cracked IAC hose. This is now discontinued from Toyota so you'll have to buy a regular hose to replace it. I'd asked the parts guy if any other Lexus/Toyota may have a similar bend but he doesn't have time to parts hunt. Part# 17341 50080 BTW

Thanks for this reminder. I replaced the hoses on the cooling system on my car a few years ago - but not a bad idea to start thinking about the rest of the system as a preventative measure.

Yup I found similar cracks everywhere
