Silly Flame Trap 200 1989

Not sure exactly how you did those plumbing changes. Have you in effect made a circuit from the crankcase up to the valve cover with a PCV in line. Have you made provision to burn off or vent the crankcase fumes. If not you will build crankcase pressure and blow oil out the seals.

The purpose of the flame trap is to stop a flame front created by an intake manifold backfire from travelling into the crankcase and exploding there. Kind of a remote cahnce but I guess they thought it could happen.
