Yukon5.7
TYF Newbie
Recently I have noticed that my 99 Yukon has been loosing about 3/4 of a quart of oil about every 500 miles. I'm lost the truck does not burn oil going down the road. There are no signs of leaks. Where else can it go..?
I have also noticed the lifters will knock on a chilly morning.
