the cranckcase in the early years evacuates with a road draft tube.... on the rare accasion with high mileage and/or dusty conditions, they can clog near the end from buildup. keep in mind they start working at about 15-20mph, so when still, its a pointless system- you need a jetstream of air to creat a low pressure beneath the vehicle in motion to "suck out" the blowby... so even a tight engine will show blowby from the breather when still. a car that sat for a long period of time may have also formed varnish deposits that bind rings, thus until some good run time and luck will they free up, raising compression, cutting blowby and also lower oil consumption past rings.... there's hope- i've had luck freeing up moisture-locked cylinders- where after less than 50 miles of driving the rings on the affected cylinder freed and no longer smoke. i like to keep the road draft tube for appearance, but you can cut it back a few inches and install a PCV valve at the end, and discretely run a 3/8 line back up to the intake and T into your brake line or depending on what carb, the rear of the carb. if it has an AFB without a rear-center tapped plug, remove the carb, and drill and tap it- that is a better location for a PCV line since it will distribute the recovered blowby to all cylinders instead of mailny to rear cylinders. -----Original Message----- From: ajl <alacaria@xxxxxxxxxxx> To: L-FORWARDLOOK@xxxxxxxxxxxxx Sent: Sat, 30 May 2009 5:47 am Subject: [FWDLK] 1961 Newyorker Breather cap Hello;
I just got my 61 Newyorker on the road after 25 years. One problem I am getting smoke from the oil breather cap. Doe anyone know how the oil crankcase ventilation works and what could be causing this problem?
