How do you get the oil out of an 88 Harley which has filled up the crankcase?

Answer 1

Answer

a twin cam 88 incher should not have that problem since the oil tank, (pan) is mounted under the tranny, but if it gets oil in the dry sump, run the engine at idle , the scavenge portion of the oil pump will lift it out, some will go back in the tank, some will go into the crankcase breather and spew out the air filter. Clean the breather out, change the oil remaining in the pan, put on a filter and don't store your bike lying down on the floor and that won't happen

Hello, I presume that you are talking about a 1988 harley and not an 88 inch? If the oil gets into the crankcase, most of it will scavenge back to the oil tank when the motor turns over. If you have a fresh battery, remove the spark plugs, put bike in neutral and if possible place a catch pan under the crank case vent (CCV). Look into the oil bag and note the oil level. Crank the motor for 30 seconds or so while looking for oil returning into the bag. Let starter cool for a couple minutes and repeat this process. You can do it the quick way, by starting the bike but if you do, be sure to have your bike out in the dirt somewhere or something under it because some oil will be pushed out of the (CCV) tube after starting the motor. This looks bad and if not prepared makes a mess for a short time. This should only take a few minutes. Be sure to look into the oil bag shortly after startup to insure oil is coming back up into the bag as you don't want to run the bag dry. After the CCV stops spewing and the crank cases have cleared (you will know this as the oil level in the bag is constant and the CCV is no longer spewing oil) you may top the bag up and go for a ride!
