Oh and Narly Dude I have never ordered from JCW. But your right I'm sure the
oil filter kit from CB Performance is the way to go, think thats who I got the one from for a 1776 engine we put in a 67 21 window came from. I was just stating you can find the same quality always cheaper if you look around. Just a service anouncement Mario Vintage Werks Restoratins thoes who can fix cars do those who can't sell parts |

Amen John! I really miss the heck out of Knight's. Leroy's death was a very sad ordeal for all that knew him. I've know those guys and have been a loyal customer for many years. Most of the time I would just stop in to BS with Angel, Dave and Leroy. I'll tell ya if you had any question what-so-ever on parts Angel was the man to talk to! I wonder what happened to him? Since the closure of Knight's I've taken my business to V-Dubfolks in Irving. They are very knowledgeable and have always treated me right, yeah you might spend a dollar or 2 more... but it's all about service and it's money well spent. As you know there is one place I would NEVER go back to......that is Piston and Plug. I've been screwed one too many times there. Narley DudeŽ |

Ideally the crankcase is closed, and the vapors are routed to the air
filter, then to the carb, and into the engine for burning in the combustion process. This "suction" is to prevent the crankcase from coming pressurized, which increases the incidence of oil leaks. Having a slight vacuum on the crankcase will pull "in" on any leaky seals, minimizing their leakage. This vacuum also maximizes the pressure differential across the piston rings, which makes them work better. The stock pulley "threads" are there only to "throw back" oil DROPLETS. The crankcase is open, and it will suck in DIRTY AIR on decelleration or other high vacuum conditions, bringing in contaminants into the crankcase and obviously the oil supply. A sand seal closes the crankcase, and allows you to EFFECTIVELY create the PCV system that makes the engine (and the EPA) happy. regardless of whether you have an open crankcase or a sealed one, you need to route the crankcase breathers to the air filter. Routing it to the open air is bad for our air, and not the best for the engine for the reasons discussed above. John Aircooled.Net Inc. "Mike Rocket J.
