question on oil catch can, st205 Options

[celicaGT96]

can someone please let me know how to install an aftermarket catch tank WITHOUT the use of the factory one. the aftermarket one that i have only has two ports and the original oem has three..

if im right i believe one goes from the pcv, then one from the block, and the other after the air filter.

Ive seen it done but i dont know how to go about it. Please help me out thank you

It goes from the PCV to the catch can to the intake. I'm not sure about the third port. It could be an emission port. Make sure the inlets of the catch tank and the hoses are big. Or you'll be hurting your motor then helping.

Just cap off the port that goes to the block. That port drains the oil from the stock catch can back into the motor, unlike aftermarket catch cans. Why not use the stock set up ?

oh i see that sounds about right. thanks man i appreciate the help. i just wanted a cleaner setup. im doing some tucking and cleaning up and this was one of those things on the list.

It's not cleaner to use the stock setup? It's more efficient that way too since it just drains the oil back into the block instead of keeping it in the catch can and making you have to empty it all the time. I would love to have my catch can drain back to the oil pan.
