Briggs 18.5 engine blowing smoke
Hi all, I have a Craftsman lawn tractor with a Briggs 18.5 hp, model 31P777, type 0348-E1. I did a tuneup using one of the briggs tune up kits that have the oil, filter, plug and air filters in it. After the tune up, started and went to cut the grass and the engine is now smoking a lot of blueish smoke. I checked the oil level of the sump several times and it is good, I don't think gas with oil was added. There is a component on the engine that has three tubes that go to the gas line, dipstick and breather, I do notknow what this. if You pull the line off of the dipstick the hose is pressurized and blowing oil. I don't get it, this was not happening prior to the tune up, had to drive the tractor from the back yard around to the garage and there was no smoke. any and all help is greatly appreciated. what do You guys think this is?
