Thank you for your help | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy SD66Burb, the short answer is yes. Whatever your engines displacement, what is displaced above the pistons also is displaced below the pistons. We don't want the crankcase to be a negative pressure area or a positive pressure area, we want the air to be able to circulate freely, hope that helps. | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | what BBB says, if you're asking about the vented oil fill cap - if you're referring to the road draft tube, it should be gone
Bill | | | | | Joined: Nov 2008 Posts: 293 Shop Shark | | Shop Shark Joined: Nov 2008 Posts: 293 | Yes, that is exactly what I was looking at. I am putting in a 350 crate engine,from my 283, so I will be running a PCV from the carb to the valve cover, but I still was going to run the oil fill tube in the intake with the breather cap, to try and look a little period correct. The road draft tube is going in the trash.
Thank you for your help. | | |
