Catch Can for 2006 Tahoe 5.3

[Scottydoggs]

I asked the question not because I doubted anyone. I asked it, hoping an answer would demonstrate the utility. I think it is a good mod. I don't know that it is *necessary*, but I do think there is enough value to add it if you can.

your 100% on track there.

I have the amazon cheapo ones on both the Silverado and Tahoe.
Tahoes catches about 4 ounces over the 3000 mile oil change interval.
The Silverado on the other hand.... gets about 2 to 3 ounces every tank of gas. So 400 to 500 miles. Depending on highway or town miles. So yeah. They work at keeping the inside of the intake clean

Is a catch can recommended or needed for these older Tahoes?

As @Scottydoggs mentioned the hoses in that particular kit, I went with some high-quality silicone hose. With winter coming, if you're in a freeze zone, make sure you keep a close eye on it or bypass for the season.
