removed the rocker cover to do the breather mod and found some thing interesting.
the above pic shows the plate that should be drilled, but on my cover the entire top bit is missing. all i have it the bottom bit with the red box around, covering the inlet stream
is this a problem?

stops oil been drawn back in through the inlet from the rocker cover, in normal form unmetered dirty oily air/vapour gets taken into the TB.
