Oil Catch Can System Installation & Inline PCV – Rebuild Video 11

Oil Catch Can

The Holley Tall Valve Covers do not have the hole on the top for the stock PCV.  They do have a nipple on the back side of the driver’s side valve cover, which is perfect for an Oil Catch Can.    In this video, I run an inline PCV from this nipple around the back of the block over to the front of the head on the passenger side to an oil catch can.  The catch can catches the oil and then another line runs from the can to the top of the intake manifold.  There is a 3rd line (the fresh air line) which is in the same location of the stock configuration.

Before I rebuilt my engine, it was consuming about a quart of oil per every oil change.  It was not leaking oil so I know this oil was exiting the valve cover via the PCV and getting dumped directly back into the intake manifold.  YUCK!  All that excess oil and carbon back in to the intake manifold and the heads, not good!

I got the catch can for $30 and mounted it on the front of the passenger side head.  Installation was cake and it looks nice too.

Tall Holley Valve Covers LS Motor Comp Roller Rockers – Rebuild Video 10

I had the Holley Tall Valve covers on the engine and in the car, but I ran into trouble when it came time to install the coils.  The stock coil bracket was no longer useable and the hole pattern from the pedestals on the new valve covers were different than my stock ones.

The whole reason for buying the Holley Tall Valve covers was because my Comp Cams 1.72 roller rockers were too tall for the stock valve covers.  Since I had to take the valve covers off, it was a good time to paint them.  I bought the cheapest option from Holley and I never really liked the way they looked.
After 3 coats of Chevy Orange and 3 coats of clear, I was ready to start on some custom brackets to get the coils to mount on the valve covers.  Apparently MSD makes some coils with the mounting holes 72 mm apart, but I had already dropped serious money in some genuine AC Delco replacements which had the mounting holes to fit the stock coil bracket.

So I had to drill larger holes in the mounting holes of the coils and I made my brackets out of a strip of $4 aluminum that I bought at Lowes, and slapped them on.  I think they look pretty good, all things considered.
