Typewriter tick

[howlins550]

Ok, well i will re-scope cylinders and try to get better pictures for you guys. The pictures like mentioned were compared to pictures of another block. That block has since been torn down and you can clearly feel the scores with your finger, that is why im kinda pissed about this whole thing.

If you read the articles i have posted about the PTWA, it is the thickness of a human hair, and if the liner was scored through, the block would need to be replaced. Now of course im just putting 2 and 2 together here but if you can feel a scratch in a cylinder with your finger, you can be sure its past that point.

As to growler with the whole smoking bs, you can absolutely have oil being burnt off and not notice smoke. If i had smoke coming out of the exhaust, not only did my point get proven, but it would be a lot worse than im taking it now.

Lastly, my friend also heard about an internal memo stating that they are seeing the liner coming off and clogging up ringlands. Take it however you want, but that is a very possible scenario with how these are put in and how thin they are.

I read so much what people may have heard, could have heard, thought they heard, it's all taken with a grain of salt now. To sum it up... combined everything you have heard from others and say 5% of it may be true.

Engines aren't blowing up left and right, nearly all 2018's/19's have the tick .. Dealers make little on warranty work and even lie to ford about what they checked just so they can get a short block or long block approved without ever popping the hood of your vehicle. When I start seeing some hard evidence, I will be a believer.

Just found quite a bit of metal flake in my cylinder 1. Will upload the other pics tomorrow, this is all i have for now.

Like just sitting on the piston?

This piece was on the spark plug, there is quite a bit on the piston and wall. I'll have those pics tomorrow, i dont have my SD adapter currently

See now this is hard evidence... Keep posting more pics!

Well here they are, I also took a picture of where the oil stays on the side, you can clearly tell the difference between the oil, and what in the original pictures looks like pitting. Also, there is one picture of what looks like to me, hot spots or oxidation in the wall as well. Was hard to see and couldnt get a great picture unfortunately.

Also note the top of the piston, looks like a bunch of metal burnt up....Also, you can see oil on top of the piston as well.

The Ford fanboi's will just say that's completely normal and to just drive the hell out of it. Isn't that what a 5 year 60k mile warranty is for? Dur dur dur.

This car honestly has me looking at a C7 hard now

That looks like carbon kinda but guess it could be metal covered in carbon as well! Wonder where it’s coming from that’s Fd up man! Hopefully ford fixes this shit with the 2020s!

There definitely is carbon build up, but I found a lot of metal flake in it. On the plug, bits kept sticking to the camera too haha. Each cylinder looks different as well which I really don't like

Pretty strange that metal flakes would even stick around on the combustion side of the piston - seems any loose stuff would get blown out the exhaust valve when the engine was running.

It looks mostly like carbon breaking off! That piston is fucking filthy! I don’t recall other DI pistons looking as dirty as the ones in this current coyote do. I’ve seen a few guys pics and the pistons are pure black and nasty looking. The carbon breaking off would score cylinder walls maybe the metal flakes are pieces of cylinder wall?

Could be that the layer of PTWA is coming off the walls ... that wouldn't be good.

That would certainly make sense. To me it seems the scoring is from carbon removing the PTWA material. Maybe the coyotes problem is simply with the new DI system causing too much carbon buildup in this particular engine and it’s breaking off! It could be the location of the DI injectors, spray angle, etc. causing severe buildup or even the piston design is causing it to excessively collect on it.

I don't get how the carbon would scratch and score though. I had a piece on the camera I cleaned off and you can break it easily between your finger and thumb. I will say however, the piston build up is ridiculous. Carbon and oil, more gunk than just carbon. The metal is like flakes though which makes me think the liner is coming off in sections, other sections (and most of) still has cross hatching
