Yeah, these things vaporize the oil and consume if I remember seeing that on here before. almost 1/2 qt here every 3K.

Just go to ebay and search catch can and you see a bunch of different pictures and such. As far as the breathers just take the pcv line off of the drivers side valve cover and the top of the intake,get a k&n breather that fits the hole in the valve cover and put a vacuum cap over nipple on the intake.

you could try switching oils. when i went from mobil 1 to royal purple i noticed my motor drinks alot more rp than m1. went from 1 quart every 3k of mobil 1 to about a quart every 1k miles with the RP. these motors seem to gulp down the royal purple.

dont forget to mention you have a higher mileage well worn ls1
to the OP ditch the PCV totally. dont worry about a catch can thats just something ppl made money on ppl with. Install 2 breathers one on each valve cover. cap all the existing lines off and run 6.5 quarts of oil in yoru rigt and youll be fine till you cahnge your oil at 3500 miles
my last two motors didnt consume any oil, id didnt route the fumes back into the motor either. Also routing the fumes which can also be oil vapors can lead to detonation. oil doesnt mix well in the combustion chamber

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
what size breathers are needed as far as the part that goes in the valve cover?

I had the same thing in my Z28. Switched from Valvoline to RP and it drank well over a quart in 3000 "spirited" miles. I switched back right away, but it continued to use more oil than it had before I dumped the purple shit in my engine.

To-do list: Built rear end, 6.0 swap with built top end, 4L80e, and a couple bottles in the bed.
if you still have your crankcase breather going into the intake manifold, plug it and put some K&N style breathers on the engine, you'll cut down your oil consumption tremendously if its being cause by RPMs over 2500 creating oil mist in the engine.

my truck is a toy though. that 1k miles is driven HARD.
