So I know that my xj leaks a little bit of oil but how can I tell if its burning oil? Will white smoke come out of my exhaust? because that happened the other day but it hasnt been driven in a while. Thanks

 

If I'm right, White smoke means it's burning coolant, blue smoke (typically on heavy acceleration) is from burning oil.

 

Blue smoke would be oil.

White smoke is one of two things. A small amount of white smoke when it's humid, cold, or just after startup that goes away after the motor warms up is normal. This is just condensation. A large amount of white smoke all the time that smells sickly sweet is coolant, and indicates one of three things: Cracked block, blown head gasket, or a cracked head.

 

ok well it was only when i was accelerating but its seems to have gone away, thanks for the responses!
