Idle too long? Burnt oil smell

[will2222]

That’s interesting - if It was a cracked valve cover would the leak be fairly obvious? I have gone over the engine best I can with but see no signs of any leaks. Plus it hasn’t had the oil smell in recent days.

I suspect FordTechOne’s explanation may be it.

Also wondering on this???

Well, an update for my truck on this one - no issues since I posted this originally. Truck is behaving normally, no oil smell. Reinforces what FordTechOne advised.

When mine was cracked it was the same circumstance. There was slight build up of oil on one of the lower valve cover bolts and would drip on the exhaust if the truck was at the right angle. i Actually had it happen twice on my 17

I have the exact same problem, right at 100k miles. If I let it idle for quite a while, there seems to be white smoke and a bad smell. I noticed it in the fall two times before it got super cold outside. I'm waiting for it to get warmer again so I can see smoke vs water vapor before bringing it to a shop/etc.

@Sonicsunspot do you have any other thoughts/updates since you posted last month?

@bentonville Nothing new for me - it hasn’t done it since the one occurrence. Next visit to for maintenance I am going to have them look for any leaks.

Sounds like a turbo seal maybe?
