2005 Toyota Camry 100600 miles. Had drive belt tensioner replaced 2 days ago, and tonight I noticed large amount of white smoke coming out of exhaust. When idle, it’s less. Engine sounds good. No check engine light. It drives normal. Temp guauge is normal. It’s an odd coincidence that white smoke started after drive belt tensioner replacement. Is it possible during the tensioner replacement, they unintentionally stressed the head gasket? White smoke is the only symptom so far. Is that enough to diagnose this as a blown head gasket?
If I sell this car, I don’t think I can get more than $2500. Head gasket replacement can cost up to $2000 in my area. Should I just sell the car as is, if someone will buy it, and shop for a used car?
