spin_dry Posted June 7, 2022 Author Share Posted June 7, 2022 My nieces husband has a 2015 F150 Ecoboost w/115,000. Front cover started leaking oil. While in there they replaced the timing chain for an extra $800. It was ready to fail. He got it back and now there's an oil leak at the rear of the motor. I've come across several overlanders with either vans or trucks with the 3.5 that have had similar issues. Timing chains and oil leaks.

My dad owns one of them and it’s showing no signs of slowing. The truck will rot out and fall apart before the motor is done Of the 3 people I know that bought the ecoboosts, one was a 2.7 and the other 2 where 3.5's. The two 3.5's had there engines replaced at around 100k and the 2.7 is over 100k and still going strong, just uses a lot of oil Quote Link to comment Share on other sites More sharing options...
