Catch can VS. Ls6pcv
I would like some help with some info. I have a 99T-A and have a oil leak somewhare and was doing some reading and see it could be a few things from sending unit to rear seal. In my research I came across the Ls6 conversion and the catch can unit. My ??? is this will the catch can do the same as the Ls6 conversion and can I do the catch can for now to help with crank case pressure? I don't want to tear into the motor now summer's almost here!!

in my opinion, the best option to go for, not only to keep crankcase pressure and blowby under controll, but to clean up the engine is to use a catch can in cunjuction with the LS6 valley cover conversion. there are lots of people with one or the other, i opted for both and love it.

I'm telling you Jay it's worth it.
In regards to my idle, mine still idles at 1k rpm. Not sure why, I've adjust my idle screw and it has come down from 1200 rpm. I can't take anymore out. But it does idle smoother since the mod has been do.
I need to find a way to verify what the tach is reading.

OP here's what I tried to post earlier
I hope this can answer your questions:
Our cars have a crappy PCV system that over time can cause oil/vacuum leaks. IMHO GM screwed the pooch (<us) by using this is a POS PCV system and on top of it, over charging us ($85-$140 depending on where you get it) for when you need to replace it.
The PCV setup runs from the rear of the driver’s side valve cover behind the intake where it splits, one tube goes to the passenger valve cover the other comes along the passenger side of the intake into the PCV valve then into your intake. In the pics below you can see where it cracks and leaks.
Pic below shows the quick fix for the PCV, it is in the Tech Section)
You can spend the $85-$100 to get OEM that will in time need to be replaced again or you can do this:
Part #: VCT - 12577927
LS6 VCT (Valley Cover tray mod) with a catch can. Some like it some don't. This is not a performance mod but it does help get the oil out of the intake. It deletes the PCV tubing and puts the PCV under the VCT and moves the outlet port to the front of the engine underneath the TB. It moves the PCV away from a direct source of oil (valve covers) and moves it underneath the VCT. It still relives the crank case pressure, just doesn’t force as much oil into the PCV.
This mod cost about $58-$75 for the VCT and about 2-3 hrs of time. The catch can goes for $50-$220 depending on what you want for style and function. Some get twin catch cans, bigger, smaller; meaning you have options.
Catch can – its function is to filter the air/oil mix that blows by the PCV. By design, GM had the blow by go into the intake and then it would burn off. However most of the time it clings to the intake and over time begins to rob it of air flow and gunk up the pistons and such.
In the pic below it's been about 6 weeks since I did the LS6 VCT and installed a Catch Can.
I wanted to see how much oil it had caught. I drained it into a cup and was a little surprise by just how much oil I had.
Prior to this mod I had to use a ¼ quart of oil every month. It’s been over 2 months and I’ve yet had a “check oil” light come on.
Couple of more things to think about when doing the LS6 VCT mod or an intake swap:
The OPSU is the tall plastic piece that is sticking up with the green cap.
(you can also see in this pic just how much oil was getting by the OEM PCV. This pic was taken prior to me doing the LS6 VCT mod. My LS1 Intake also had as much oil on the inside.)
These can get brittle and break over time. Also when you are messing with the intake most first timers break it because they don't know it's there. These can leak quite a bit of oil. Signs of this are oil coming down the backside of the engine over the bell housing. It is commonly mistaken for a rear main seal leak.
99’-02’ Knock Sensors – 98’ and older GM is no longer making, If you’re like me you will need to upgrade to the 99’-02’ KS sensors (x2) and wire harness. Even if you have a 99’-02’ KS it is still a good idea to replace them. Remember it’s better to do it now while you have everything off then have to come back later.
Part #’s”
KS (x2) - 12589867
KS harness – 12601822
Hope this helps.
