Re: 2001 Windstar is burning oil
Get a compression test done. If any cylinder is low on compression then the piston rings are gone and you should get a new engine ASAP. If compression is fine it could also be a valve issue, where a valve doesn't seat correctly due to warpage, or the most common - carbon buildup. Seafoam or Auto RX are good at getting rid of excess carbon/sludge buildup in the engine. Again, that's if your compression is OK.
Be sure to change the plugs every 40,000kms with copper tips. If you go with platinum or iridium it's a waste of money as you should change them every 40-50K kms anyway for best performance and so the plug doesn't seize into the head!
