If we replaced oil pan with part number FT4Z6675D but neglected to do valve covers as referenced in the TSB could that cause the car to start smoking intermittently?
My parents have a 2017 Continental with the 2.7 turbo. It has seen meticulous maintenance from them with no issues other than the terrible oil pan leak. In December my husband replaced the oil pan with an aluminum pan purchased on eBay and the OEM gasket. It's an aluminum pan part number FT4Z6675D. A week later they drove 1500 miles to Texas. On the trip my elderly dad thought the engine sounded noisy. He stopped and checked the oil and it wasn’t showing on the stick. He added oil and said it quieted down. He then began checking it and saying it was reading low about every time they fueled up so he was adding more oil. We went to visit them and my husband replaced the PCV valve, looked for leaks, put ats205 in it. Since returning home the car developed intermittent smoking issue. Husband then replaced left side turbo since it seemed to smoke more on that side. Smoke cleared up for about 3 weeks. Car then started smoking again. Another shop checked and says oil (my dad had added again) when car is first started oil reads low and then after an hour reads over full. Their hypothesis is worn valve guides or heads. Car runs great, sometimes smokes, sometimes doesn’t.
Brian is wondering if this pan could be causing drain back issues. (Missing or covered passageways?) He did NOT replace valve covers as is referenced in the TSB posted earlier in this thread by @Haz. Could that be contributing?
Hoping to get some insight. Have you run into anything like this?
