my 2.0 l engine smokes from a hose on the oil fill cap this hose goes to the air filter housing and the speedo jumps at speeds over 15 miles per hour any idea what to do to fix this

The only thing I can tell you is that its and old truck and that speedo is gonna jump a little no matter what. My 88's speedo does the same thing.
