Quoting 4thStroke:
Will you make a new thread when the valve cover is installed so we know what a fresh red powder coated valve cover looks like on a nile black VR4?
I don't believe anyone has put extra/larger holes in a DSM valve cover for proper crank case ventilation... ever.
While that may be true about a dsm valve cover, you might want to look at the one lap car, which leads me to the next point... why put them on the top instead of the side?
