As you'll remember, because I am the center of the universe and everybody remembers all of my posts, I had a PCV problem. I was trying to run PCV with no baffle in the PCV valve cover, it was removed for rocker clearance. I put a coalescing filter in the PCV line to catch the oil until I got around to doing the LS6 valley cover upgrade. I was dumping the bowl on the filter before every drive, and dumping a quart of oil in the engine when the "check oil level" light lit. I thought I might be sucking a little oil. and burning the rest because maybe the rings weren't yet seated. Well, I definitely was burning it, but all through the intake! I spent the day flushing out the blower, the inter-cooler, the piping and the intake manifold. Now maybe my boost will drop a couple of psi with the blower dry. I also put in a picture of an LS6 valley cover, I installed it before I realized I should have taken a pic of the underside to show how humongous the oil baffle is. I wonder if this oil burning would lower the fuel's octane enough to cause my knocking? http://homepage.mac.com/michaeldritz/PhotoAlbum20.html

 

Burning oil will definitely cause knock.

Holy ****, that's a lot of oil in your pipes!

 

Holy **** is right... so I'm missing why you're getting oil in the blower in the first place. Did you run a hose from your valvecover to the blower inlet?

 

I wonder how much. I will find out when this tank empties if I still have to lower my boost. It has what is probably 96 octane, a 50/50 mix of 93 and 100 octane to make sure my knock wasn't false. This mix fixed the knock.
Yeah, I tapped a fitting into the inlet so that the PCV would only see vacuum. I was assuming that guys have problems with PCV and boost because they have their PCV going into the manifold, and PCV won't work in boost. And because I have a Whipple, the valve covers are reversed, so the PCV valve is in the front right cover. I picture the rocker boxes filling with oil during a WOT run, then I hit the brakes, all the oil goes forward, and then gets sucked straight into the blower.

 

Is the LS6 valley cover that much better as far as stopping oil from entering the pcv tract? I had no idea this was available thanks for posting up.

I wish I knew about when the engine was going together, it would be nice to only do it once.

 

Mine is setup similar to your but I dont get the oil consumption. I get about a tablespoon or so in my catch can every oil change. I also still have baffle in the vavle covers as well..

 

Nice baffle

 

I wonder if my engine builder was supposed to restrict the flow of oil to the top-end with my roller rockers, and didn't? I think it is probably all due to not having the baffle in the PCV-side cover. Yours sounds like what was being descibed in the LS1howto.com article, just an annoying amount.

 

How much did that valley cover run you?
