5.3 catch can install

[BigPac]

installed an Amazon catch can, exactly the same as the one CORSA advertises. Said it was for 6.2 Camaro but fits 100%. I do want to clean up the hoses and add a drain valve in the 3/8 pipe plug but for now works. I do recommend and "hook tool" to compress the connectors on the OEM fittings.
FYI all that sludge is from about 100miles

Good install job. Measure and record the oil fluid caught and mileage at each emptying.

New here, ive seen people talking about this. Nothing recent enough to comment, what an why the catch can?

All the junk from the PCV system is routed through the intake runners and intake valves. In a port injection engine this is no big deal since gasoline is a cleaner and is sprayed into the intake runners\onto the intake valves. On direct injected engines, the gas is injected directly into the combustion chamber so it never gets a chance to clean the intake runners or valves. Add a catch can to to the PCV system to "filter" out this crud, and empty the catch can when needed.

Depending on how many miles you have, you might want to get the intake valves cleaned. You can do it yourself (I did with walnut blasting) or pay someone to do it.

How did you do it yourself with blasting walnuts? Is there a video you referenced? Thanks

I installed one on my ‘24 yukon right off… the more i read on it.. it looks like the coking on the intake valve.. the hardness of opening it with coked on the intake.. is what busts the rollers/afm.

I am going to add in another catch can so nothing gets past into the intake.. i have 1/4 cup in mine with hwy driving.. each 3k… or so.

Just an update after 3-4 months, recommend updating the oil lines from the crankcase vent. seems the hoses in the kit are not suitable for oil, they have weakened and swollen and will star to collapse . could just be a cheap kit (which I got lol)

NEW UPDATE, purchased some new catch cans that were labeled on the housing. The Inlet had the screen filter on it, and the outlet was the open side. looking at the one i had installed it incorrectly possible? is the in coming from the engine, or going into the engine? i have swapped them, but now i doo see significantly less oil in the catch can? they do not have a check valve and can be ran both ways. But would assume the hose coming from the crank case would be open and the filter side on the catch can would use the " filter side going to the intake manifold?

Good question ...
You need to understand in which direction the PCV system runs in your particular application.
You want dirty oily vapors coming from crankcase to pass through catch can so it ... can catch ... the dirtiest oiliest stuff,
so your intake breathes air that has been cleaned by the catch can.

What I said is not specific to your application, but once you get it you should be able to understand how to install a catch can on any engine.
