Diy catch can install

[cjweb11]

Just drained he can for the first time after an oil change, probably was about 4000miles since installed. Looks like its right around 1 ounce of oil was trapped, well see again in another 6000
Money well spent

One ounce ain't bad after 4K, but when the miles rack up and you have more blow-by then having a CC would be something everyone IMO should consider installing.
Might as well install one sooner than later.

why not just run it to the frame rail and leave it open?

You can do it that way if you want, I did it that way to my Diesel.
The reason for the catch can is you will pass emissions without any BS failure.

just making sure there isn't a mechanical reason. no emission crap here, hasn't been since '96

You might ask this ? with a mechanic. With these gassers you only use the driver side PCV for the catch can. On diesels you vent out both-sides for the PCV open system or closed.
IMO with a gasser I feel it would be better to use a CatchCan closed system.
JMO.

Why do we only use the drivers side? Why not the passenger side valve cover?

Mine should be in today and going to do this mod sometime this week. Thanks!

From what one membes said you could do both sides, he said the majority of the vapors at least 90% come from the driverside.
The dealers refers the passenger side PCV as the clean air intake, the driverside PVC is the dirty air intake. This cleared it up for me to just do the driverside.

Now that i think of it... Both cylinder heads drain oil down into the same crankcase

Why would one side differ (clean/dirty) if at the end they both lead to the same spot?
