1999 Lincoln Navigator Q&A
1999 Lincoln Navigator Question: is it normal for the exhaust to smoke white after changing the spark plugs.
it was not smoking before the change. When we pulled the plugs out there was oil/brown liquid. The vehicle has 217,000 miles on it and I bought it from a gentleman who has owned it for about eight to nine years, he has never changed the plugs. It was missing a little bit so I decided to change them and that what I found and when we started it up after wards it smoked real bad. Will it go away or should I take it in and have it checked. - BriaJay
WHITE SMOKE USUALLY IS THE RESULT FROM HEAD GASKET LEAK. If your are able to smell an antifreeze smell , t hen that will confirm head gasket leak. GOOD LUCK. AND NO IT IS NOT NORMAL AND I DO NOT THINK IT WILL GO AWAY. You should have it checked by an experienced mechanic. - jims56chevy
