:|Between oil changes of 5k what oil consumption are your LS2's using. Down 1 qt. Dropped the TOY off to get coolant usage diagnosed. Hope nothing serious. Already cancelled Daytona. DAMN.
Don't worry about a qt. in 5k. GM's point for oil consumption is 1 qt. in 500 miles. Mine will use between 1/2 qt. to 1 qt. between oil changes of 5k. All depends on how I drive it.Between oil changes of 5k what oil consumption are your LS2's using. Down 1 qt. Dropped the TOY off to get coolant usage diagnosed. Hope nothing serious.

From previous threads on this topic, your oil consumption does not seem out of line for the LS2. I haven't really noticed much oil use on our R's, but they are not daily drivers and generally only get 1 oil change per year. Years ago on O-YLR I did perform Topspin's PCV re-routing and did notice that the tailpipe tips didn't soot up as much. You might want to consider that modification if you haven't done so. See link below:Between oil changes of 5k what oil consumption are your LS2's using. Down 1 qt. Dropped the TOY off to get coolant usage diagnosed. Hope nothing serious. Already cancelled Daytona.

Would definitely recommend trying this first. Today I had a chance to reroute my PCV hose as Topspin suggested and it resolved the smoke coming out the tail pipes.From previous threads on this topic, your oil consumption does not seem out of line for the LS2.

Dan posted some great pics in post 70 of the above thread.
Thanks for the pictures. What type hose did you use. am worried about collapse. How much did it smoke on start up and did it do it all the time or just hot restart. Going away for a week plan on doing this when I get back. I assume the hose you unhook off driver side valve cover you just plug that cap it off I can't really tell in the picture thanksWould definitely recommend trying this first.

Don't forget to cap/plug the tube on the valve cover with the cap you take off the valley tube!!Thanks for the pictures. What type hose did you use. am worried about collapse.

Thanks , that is the answer I needed. If this solves my problem, I'm going to be happy but also POed. Cancelled Daytona thinking the worse.

Gates 27053 Rubber Vacuum Hose it has a really thick wallThanks for the pictures. What type hose did you use. am worried about collapse.

Keep an eye on the hose after you drive awhile and it gets hot under hood and its subject to high vacuum on deceleration I finally ended up making a fitted tube out of copper tubing. It was easy to bend to shape and doesn't collapse then I just connected with 1 or 2 inches of hose at each end. Problem solvedGates 27053 Rubber Vacuum Hose it has a really thick wall
Mine was smoking just as you described yours is and it did the first time just a little after I did the reroute however now it doesn’t do it at all.
Yes, took the rubber cap from port on the valley cover and moved it to the port on the drivers side valve cover.
Did you have to re-route the hoses because of the custom covers or work you did or should we all do it? Just wondering.The jury is back and we have a good verdict. After rerouting the PCV hoses as per all the excellent advice we have no smoking on start up and no oil consumption. Thanks for all the input.
I'M not a 100 per cent sure, but the chrome valve covers did not have baffles like OE. Did not want to take them off to find out. I just followed advice and rerouted the hoses. Problems solved. I do believe the tail pipe tips have less soot.Did you have to re-route the hoses because of the custom covers or work you did or should we all do it?
