I have to disgree, the PCV system is only able to handle a reasonable amount of crankcase gases. If an engine has HUGE BLOWBY the PCV system will be overwhelmed and large amounts of oil will get forced back into the intake.
I'm not sure why builders don't test BEFORE the engine is in use? If it has alot of leak down its going to smoke and push oil into the intake if the PCV system is used.
A well built engine will have very little blowby and what that means is it has well sealing cylinders. This mean low leak down and no smoke out the oil cap. Also means the stock pcv system will work just fine.
Anyone that has oil and smoke trouble needs to check their leakage and go from there. Whats acceptable leakage for the amount of money you pay??????

Please have a leak down test done and post up the numbers. Be sure its done with the pistons at TDC and BDC. This will check the entire cylinder for leakage through its stroke.
