Default Catch Can?

I'm new to the catch can. What is it for? Where does it go? Is it too late at 111,000 miles????

Here's a primer for you:

Is it an exact science? No, not by a long shot, but I am working on coming up with something that is engineered, rather than thrown together.

You don't need any software to search or search this forum (in the red banner) in C5 Tech.

Use keywords "oil catch can" and plan to do lots of reading.

It's purpose is as simple as the keywords...catches oil in a container before it can enter the intake system.

And it's never "to late"...

To answer your previous question - no, it is not too late, since oil does not evaporate - it accumulates/pools in your intake. Over time, your compression ratio will increase as the volume of space abobe each piston is reduced when carbon builds up. And unless you increase the octane of the fuel you use, your ECU will "hear" the pinging and reduce engine power.

I still think you should read the article............

No mean to HIJACK, but is there anything you can do to I guess 'clean' the intake if a car has not had a catch can on 100K miles?? What sort of thing scan u do to remove this pooled up oil?

The easy way is to take off your Throttle Body and just reach in and mop up the oil.

The best way is to remove your manifold and clean it...

I've put one on and I'm glad I did. First time I checked it after several months there was probably an inch of oil in the bottom.

The backlash from consumers being told they'd have to empty a can every few months because of an imperfect engine design would be swift and brutal. Many big rigs and busses use air/oil separators, but the collected fluids are either routed back to the oil pan or are contained in an isolated tank. Filter experts agree that you should never expose outgoing air to collected liquids, so If GM included a filter, it would not look like a typical catch can, which allows the outgoing air to entrain oil that is sloshing around underneath it. It would probably look more like a miniature version of what the big rigs use.

I had to put two on because my LS6 (in my V) has outlets on both valve covers.

The driver side is the one that seems to "catch" the most oil.
