I believe some of the sludge and build up is due to direct injection but most of it is due to the previous owner not changing the oil. I've only put 12k miles on the truck since I've had it.

I'm going to trade it in tomorrow unfortunately (I loved my truck). I'm looking at trucks with 30k miles or less. Would it be worth getting a 17 bc of the port injection. The price difference between a 15 and 17 is about 5k.
You need to be more specific about the reason for the motor being about to let go. What is worn out exactly??

I had a 2011 3.5 EB and it had the timing chain rattle fixed. That is a known defect with those trucks, the chain/tensioners wear out prematurely. Its an expensive job, but one that should not have to be repeated. You also may have some success getting ford to pay for some of it, even if out of warranty.

I had mine done at 100k and it looked flawless inside. No visible wear on the cams, clean, no sludge.

The injection issue you speak of will only result in some buildup on your intake valves that may rob you of a little efficiency after 100k+ miles, but it will not hurt your engine. Mine had 160k on it and ran like a top when I sold it. I have no doubt it would have made it another 100k without issue.

This is everywhere in the motor. In all of the oil galleys, everywhere, it's a mess and a damn shame. My mechanic who I've used several times and trust said it's the worst he has ever saw. Previous owner did not change the oil. My plan was to fix the timing chain and drive it another 100k miles. Rest of the truck is in great shape. I'm pretty upset over the whole deal.

Couple heavy doses of Berrymans and flush. Then replace 1qt of oil with 1qt of transmission fluid and change every 1000 for about 3000 miles. Clean as a whistle.

Holy crap! You weren't kidding. That is the worst I have ever seen...

Mine was absolutely clean as a whistle as I mentioned, at 100k miles. Yes if the compression is still good, and there is no visible spalling on the cams or anything it can probably be cleaned out and run for a long time. You'll want to change out those oil control solenoids visible in the pics too. However, it may not be a bad idea to just move on.

Iím going to try and trade it tomorrow, unfortunately. I was looking forward to no truck payments.

Sounds Ike itís not worth the extra 5k for the port injection.

I'm not a Ford guy, but that sucks. I'm sure you are getting a huge hit on trade in and someone will clean that up and get a ton of miles out of it. Are you sure you can't just get it cleaned out?

Iím not really a ford guy either. I go with I think is the best truck at the time. 2011 to now is ford IMO. Although I think ram may be taking that away from them.

My mechanic said the only only way to clean it would be a a tear down and he didnít recommend that. You canít clean a turbocharged motor like a natural aspirated one. It will take out the turbos.

The only place i could find a complete long block was from ford $5100. Then Iíd have to pay the install.

The timing chain rattle is fixed for now. Itís going to come back soon tho. If heads and cams look like they do I can only imagine what the rotating assembly looks like. Itís not a gamble Iím willing to take. Low trade in for the truck is 10k. If I can get that I will be happy. I paid 16 for it.

It's crazy how people refuse to change their oil when they are supposed to. For most people, their vehicle is the second most expensive thing they will ever own. This is a v6 hyundai. Told them to junk it and they didn't listen. Put chains in it and it knocked. Your truck might be worth fixing though.

The sludge has nothing to do with the injection system. Your oil and fuel are separate. Port, direct, carburetor, TBI...none will cause or contribute to your issue.

Btw the new ones are direct injection as well. They just also include a port injector on each cylinder.

Mine looks worse than that picture. What makes you think I could save mine? Iím not arguing your statement. Just curious.

I mean it might be worth putting an engine in it.

That is all purely due to a lack of maintenence. All the DI does is carbon up the back of the intake valves.

Now, button it back up and you can slowly de-sludge it. Lots of posts on BITOG about it. In 10k miles it can be pretty clean.

I agree that you have a problem, but before you get downhearted you should research the problem a little further.

I would suggest going on the big Ford Truck forum and throw out the pictures to the experts on the motor. They easily can tell you what your options are. It might be as simple as running Marvel Magic Oil, Liquid Wrench or other such liquids thru the engine. But since it's a turbo motor, get good info.

There are so many half ton trucks totaled out that engines are very easy to find. Unfortunately, 2011 used motors with warranties that are low miles are in the $4000-$4500 range. It's usually about a 1 full day job to switch out the engines.A new Ford engine BL3Z-6006-CARM can be bought at AutoNation Ford of Bear Lake (MN) for $4594 plus $1000 core charge--the cheapest source of new Ford Parts. They are actually a bargain vs. high mileage new engines. Most of the new engines have had inherent problems of the past fixed and they have a 36/35,000 mile nationwide warranty.

Likely best to Trade it or Replace the Engine the magic cleaners are not going to cut it you start breaking that sludge down & it will end up clogging/restricting the oil pick up screen plus plenty of small passages that are likely partialy clogged already.

That is exactly what my mechanic told me. He is a good mechanic that me and my family have used many times and he has always been honest. When he called me about the sludge you could tell he felt bad and really didnít want to tell me.

If the engine locked up going going down the highway I would have just slapped a new motor in. After paying 2k to get the timing chain fixed (I told him to go ahead and complete the job since he had it tore down and I had already ordered the parts) then knowing a complete long block was inevitable I wouldíve had close to 10k in repairs. I just couldnít swallow that much change on a 9 year old truck. Traded it in on a 17.

Whoever owned that truck before must have done 20k mile oil changes those motors should be done no less than 5k miles because it's a over head cam motor and synthetic oil must be used or motorcraft synthetic blend oil the motor sludged up because of being over maintenance.Damn shame people can't take care of their vehicles I work on diesel's and I see the same kind of stuff but not that bad ive seen plugged fuel filters that weren't changed when recommended and customer bitches truck has no power or a injector went bad because of the plugged fuel filter.

I would have liked to have seen if it had a production line filter on it. It looks like the oil was never changed. This happens more often than you would think with lease vehicles.
