Early LS motors like mine did have a few
oil problems. I believe they run quite low tension on the rings so had a bit more blow by till well broken in. This made for a lot of
oil vapor being pumped into the intake. When I pulled the manifold the ports were quite wet.
You may remember some complaints early on from Holden owners about their
oil consumption.
The LS has gone through several generations of breather setup to combat the oil going into the intake. When I built this I just figured I'd eliminate it all together.
