When it comes to having trouble with something as important engine of your vehicle i would always suggest you to take it to your nearest memechanic and get it diagnosed and repaired as early as possible as overlooking such a problem may lead to a bigger trouble and complete failure which might led you to having a major over haul, and would cost you dear.

It sounds like a lifter is bad and is not getting oil pressure, or the lifter or it's bore is scored.

The knocking of engine isn't a normal issue no matter how many miles it has done and there has to be certainly some trouble in the vehicle and you do need to get another view about it and does ensure and get it diagnosed before it leads to any other trouble.

They've (3rd Ford Dealer) had it for a week now, and probably will have it most of next week from the sounds of it. Right now, they've said that it's not in the block etc..so not in the engine, but they feel the knocking is coming from the header exhaust somewhere. There going to test the piston ring pins?? by shutting down cylider at a time to see if the noise goes away. Frankly it didn't sound like they were that confident and also made the comment that it maybe something that just cant be fixed..???WTF???? What does that mean?? I just want my truck to sound like everyone elses...normal. If its exhaust related, wouldnt you just replace the parts that are making the noise???? I've issued them per council "fix it, or buy back"...so..we'll see I guess. To expect a customer to just deal with it, and to say its just one truck out of thousands that happens to be loud is rediculous...I will NOT accept this...

Well not in the block to me mean that the problem isn't coming from the lower half of the engine, like the shortblock. There are so many moving parts in the top half of the engine. Hopefully they can pinpoint the problem soon.

Ford is so close to having an engine that just purrs, but no, every engine has to have a knock,tick of some sort, just enough to be embarrassing and frustrating. How much longer do we all have to put up with this????

I wouldn't accept that either, nobody should. Just hope you don't end up having to deal with a mentally impaired regional manager like another poster on here who had tons of problems with his eco boost, she told him it was going into limp mode because the eco boost isn't designed for towing. https://www.f150forum.com/f38/ford-f...issues-157704/

Wow...I was waiting for Ford to send me a bill. Why you ask? Simple, I didn't pay for that noise!! Anyway, the RSM that I'm dealing with is Marysol. She seems somewhat responsive, but really it's been the final notice of defet sent to Ford that's had the best results. We'll see. Trucks been in for 9 days now. I was just told that one of the techs is going to take it home tonight???

SO...I thought I'd update everyone who's been watching this post, or at least commenting on it.

As the poll at the top of this thread would indicate, the engine noise (knocking) is in fact NOT normal.

As I've said in this post and others, that I've had this truck to several (3) dealers and has been in the shop collectivly for almost 4 weeks. It's been for the most part dismissed, stating that it's normal and NO harm or damage will be done (yeah right!).

Slowly, I have been putting a lot of pressure on FORD to fix the problem; the last was an official legal notice of defect to Ford Motor Company - per counsel advise. This seem to get the engineers at Ford engaged in finding a solution..and really, admitting that it was not a normal sound.

After two weeks of testing, the truck was ticking away and they one by one shut the cylinders down. Low and behold, when #4 was shut down, the knocking stopped. After further investigation, the #4 cylinder is "oblong". When the at top-dead-center the piston is slapping around. I will say the the dealer was very aggressive with Ford, and really pestered them. Ford in turn, was very MUM on the potential problem so that they wouldn't start "throwing" parts at it.

The fix? Complete engine replacement. Yep, they are replacing the entire engine (long block): everything but the intake and ancilarys. I'm negotiating other compensation, but extended warranty etc for sure will be included.

So, for those of you who have this issue, or do in the future...somthing to consider is a defective bore.

Thoughts??

It should never have had to get to that point of council in the first place. Just fix your damn product, and make your customer happy! Is that so hard, ford?
