What difference have you observed it make?i put one on as well as many others have. i made the bracket and got a cheap can off amazon, 25 bucks at the time. if you get the cheap one, the hose they give you is trash, so you'll need to buy some real hose.
A recommended mode.Is a catch can recommended or needed for these older Tahoes?
Yes, doesn't matter if it's a 4.8L, 5.3L, 5.7L, 6.0L, 6.2L, 6.6L, or 7.0L.Is a catch can recommended?
you'll notice no difference. but you'll have piece of mind that that oil in the can is not laying in your intake. mine is ran right off the top of the pcv valve, so what its catching is what would end up in the intake.What difference have you observed it make?
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.you'll notice no difference. but you'll have piece of mind that that oil in the can is not laying in your intake. mine is ran right off the top of the pcv valve, so what its catching is what would end up in the intake.
