Hi Guys,

I could do with some advice. My LS3 has been breathing alot from the valve cover breather on the passenger valve cover.

The oil is collecting in the catch can I have fitted but am a bit concerned its breathing too much. It only happens on WOT and high load when its on track.

Just wondered what kind of volume, if any, to expect being sent out that breather???

Hope you guys can put my mind at rest.

Thanks

better do a compression test or leakdown test if you have that much back pressure you could have a hurt piston
