My 97 f350 is getting pretty lazy to start. When it fires it still seems to have all its power but just seems lazy. Pull the dip stick while the truck is running and there is quite of bite of smoke coming out of the dipstick. And oil is getting all in my airfilter also. any one eles have this problem. The old girl has 230,000 miles on it. Like i said it still seems to have all it power and all when running
