So my truck was diagnosed with a streched timing chain at 105,000. I live in Denver but am currently working in San Diego. I decided to replace the whole engine. Sourced a 2019 engine and transmission with new miles on it (approximately under 100). Donor vehicle had engine removed for V8 supercharged replacement. Mechanic that i was referred to did the swap and I currently have about 20-25 codes throwing. He kept the 2019 harness on the engine instead of putting the 2017 engine harness on the 2019 engine. Im assuming the main harness plugs are wired differently. Wondering if any techs could aid me in this situation.

Who diagnosed the “stretched” timing chain and why would you replace an entire engine for a timing chain issue?

Just pay for any replacement. Get it going, and dump it as fast as you can. The engine harness for the engine should be fine, but just dump it. Move on to something else.. like a gen1 that doesn't have these same problems over and over.

These engines don’t have the “same issues over and over”, your posts are the same ******** over and over. All you do is troll threads with your regurgitated, misleading nonsense.

The OP asked for help and you told him to get rid of his truck...you’re not here to help anyone. Funny how you have so many accounts as well, why are you so jealous of Gen 2s? It must be tough to go through life with such a severe inferiority complex; you should seek professional help.

I would also like to know who diagnosed it as a stretched timing chain, what symptoms you were having and how come you replaced the whole engine. Not super common but timing chains do stretch sometimes. Ive seen them in Hondas, Minis, Audis and others. Most cases is always negligent. Usually not keeping up with oil changes or poor/wrong viscosity oils. What are your codes? How can someone help you if you don't even say what the codes are.

Or have I been "sasquatched" as you guys always say??

Almost sounds like the case of having a noisy rear end wheel bearing and the guy decided to replace the entire rear axle assembly. Why??????

Suspicious

The Gen 1 3.5L EB engines are notorious for timing chain issues. Seems to not be as common the Gen 2 engines.

Chains do "stretch". It's not actually stretching, it's simply wear. A tiny bit of wear on every link and roller all adds up to a sloppy chain. The longer the chain is- the more it becomes an issue. It's not a problem until the tensioners run out of adjustment range, but then it immediately becomes a really big problem.

I agree that replacing the engine for a bad chain seems a bit, uh, strange? That's like doing a full gut of your bathroom because the wax seal on the toilet leaked.

OP should fix the original engine and put it back in.

This is a weird thread but it's true that the 17 and 19 sensors are a bit different. Not sure if it's a completely different wiring harness but it wouldn't surprise me. The tech that did the engine install should know. If not then a quick call to a Ford service center would answer the question definitively.

Depending on the deal you got I can see why you'd swap out a 100k mile engine for a new one just not sure why the guys doing the swap didn't address the wiring harness issue up front.

The harness from the 2019 engine was making the vehicle throw 20 something codes the mechanic swap the harness is putting the 2017 harness onto the 2019 engine basically all the codes disappeared except for one the driver side waist gate is slow to respond. The symptoms for the stretch timing chain was the crank pulley was wobbling like crazy I wouldn’t exactly call him a tech and the reason I put in a new engine I felt to have a new timing chain and 105,000 miles on everything else I felt the new engine would be the better way to go. I kept the old engine I do plan on putting a new timing chain in it Possibly selling it or even building not sure exactly yet
