2004 Lincoln LS Q&A

2004 Lincoln LS Question: At idle have exhaust fumes coming thru aircondition system

Was told it was the PVC hosing on top of engine...replaced...after 2 weeks same problem. Was also told the head gasket was NOT leaking. Smells like oil burning! -
Answer 1
Check for oil leaking onto the exhaust system. Check the valve cover gaskets, as these are right above the exhaust manifolds -
