...Why do You think You need a 'Catch' Tank??? So You can 'Save' Black Smelly Oil, and Look at it, as You drain the Tank Out!!
I figured these 'Vapor Seperators' Out, with these parameters, with attention paid to the Physics of Gases and Liquids...Vacuum and Gravity.
As said long ago...I hated Breathers!! They stink! and The, what little, Fumes/Smoke, comes up and over the decklid and is seen in the rearview mirror.
Parameters:
1) NO Catch tank, absolutely INCLOSED System.
2) ONLY Vapor is Burned in the Engine, NO Oil is to Enter the Manifold, and Especially Not to enter the Carburetor.
The Design:
1) The PCV Valve is inserted into the Right Rear Rocker Cover. Oil is Stopped at the First 90 Degree fitting, this acts as a Restrictor, The Seperator, itself, acts as a 'Expansion Chamber' where Vapor 'Can' Form. From there, the Vapor is drawn into the Manifold at a fitting Below the Carb. On the Manifold NOT the Carb.
2) The Second Seperator is at the Forward Left Cover. From the Exit, the Vapor is delivered Under and up through the Filter Plate, and exits Inside the Filter, Between the Filter and Opposite the Holley Primaries. NO Oil has ever Appeared Here! No Hose clamps are needed here, as we are dealing with Vacuum, and the Hoses Fit Tight.
The Physics:
The Two Systems MUST NOT be In-Line...The 90 Degree Fittings are the KEY! This is a Restriction, that Dis-allows 'Suction' of the Oil, Along with the Expansion Chambers.
The Entrance to the Seperator MUST Be lower than the Exit! This allows for a 'Drain Back' into the Covers, by gravity and by the reversed direction of the Air Flow, as in Idle...WOT...idle.
Being transparent the Expansion Chambers provide Proof , No Oil is getting to the Manifold and Carburetor! As Witnessed when removing the intake Filter...On the Carb, No Oil, No Dirt!
That about covers it. Any Questions, Ask.
P.S. Anyone Still want a Catch Tank?? I have one for Sale, NEW. I'll post a Picture....Gorgeous Chrome Steel, about a Quart or Less. Photos to Follow!
