2003 Ford Windstar White Smoke
It seems like it takes about 3 yrs for the defect to show up. Maybe there will be more complaints as time goes by.
Suggested Repair
Have a Ford dealer perform a cylinder leakdown test to confirm whether coolant is entering a combustion chamber from a failed head gasket, a known 3.8 issue that can bend rods. Verify the installed engine serial number to confirm it was actually replaced, and limit driving until the leak is diagnosed. Unseated valve stem seals typically cause oil burning and blue smoke, not white smoke.
Conversation Summary
The owner of a 2003 Ford Windstar 3.8 V6 reported heavy white tailpipe smoke. A shop first found nothing wrong, then later reported bent rods and a cracked O-ring and replaced the engine, but the smoke continued. Experts said white smoke indicates coolant and is commonly caused by head-gasket failure on this engine, which can damage rods if coolant enters a cylinder. They recommended a Ford dealer leakdown test, checking any applicable extended coverage, and verifying the replacement engine's serial number. A later report of unseated valve stem seals was identified as more consistent with oil smoke than white smoke. The owner said they were dealing with Ford and awaited further results.
