Ford is replacing the long block - corroded cylinder

[Lcr3000]

(Part 1 of 2) I was hoping to evade this problem, but it seems I've fallen victim to the ol' water draining down onto the spark plug issue. My 2021 (1st revision 2019- early 2201) Ranger Tremor has 57k miles and has run fine until it suddenly didn't, this past Saturday. Driving it down the highway at 60mph, it suddenly started missing on one cylinder. I pulled on to a safe distance off the main freeway and took a look under the hood. I couldn't see anything identifying the issue (I was looking for maybe a loose vacuum or something like that). Water level was ok. I decided that it could limp the remaining 7 miles home with it sputtering. Monday, I limped it into my local Ford dealership and left it with them. I've got a good service agent, so I'll spare the Ford review here. It is now Friday and after various diagnostics the company requires to approve a fix, the verdict is in. A cylinder is corroded (assuming #4), and the plug is burnt up (black). The order for the new engine is in. The arrival will take a week. Install, up to another full week. I'll follow up with the situation once all has been completed. I did ask if the new block would be the newer revision. The answer is yes; they will only put in whatever latest revision is of that particular engine (which is the late 2021 - 2023 revision). The factory power train warranty covers all of it including my loaner vehicle with one exception, the spark plugs. I'll have to buy those (16$ a piece) I know, kind of petty right? The real question is, will it come with the engine cover, being that Ford does have a TSP open suggesting putting one on. Even the tech doesn't know, but we'll see. If not, I will purchase the newer one. (2 of 2 coming soon)

Sorry to hear that happened to your truck. Hope that they'll make it right for you.

Sad story but really glad to hear Ford is taking care of you.

Sorry to hear about your Ranger and glad to see Ford is taking care of it for you. It is pretty cheap of them to not cover the plugs and you'd think that they'd just throw them in considering what you're going through.

If it doesn't have an engine cover you could always PM Benny @LevittownFordParts.com to see if he can help you out. Patrick @My12SecRanger sometimes gets them in too so between the 2 of them you should be able to get one reasonable.

Edit: If needed, Patrick has one for sale now.

Glad they’re taking care of it for you. But what is the “revision” ? Never heard of that before.

My 2021 came without the engine cover and when I asked, they told me that Ford discontinued using it because the cover was keeping too much heat over the coil packs.

Is this the cover that goes over top of the engine?

Sounds like you are not sure it is cyl #4. Water in the spark plug well shouldn't find itself scarring the cylinder wall, but a leaking head gasket would.

Usually water in the #4 spark plug well corrodes the spark plug threads and causing them to bind to the aluminum threads, stripping out the head threads when you attempt to remove the spark plug. That outside water never finds it's way into the cylinder. Usual fix is to replace the head.

It sounds like you had bigger issues. I've seen cylinder corrosion only when cylinder heads crack or cylinder head gasket fails and water begins seeping into the combustion chamber. The corrosion occurs after the engine is shutdown and the engine heats up before cooling down. The head gasket allows water to seep into the chamber and collect/sit in the cylinder until you start the engine the next morning. The whole time it is sitting it is eating away at the cylinder wall. Once the engine starts, the water is vaporized and goes out the exhaust. I've seen it several times in my life. It takes a while to show up as corrosion. I suspect it has been failing for some time, and simply reached critical mass.

I'm really curious to see which cylinder the failure occurred in.

 

[airline tech]

yes - this had me puzzled as well - Ford approved an engine assembly for something that can be replaced (head) - even so - with some finesse the plug will come out - you just have to know the tricks - and #1 if the plug shows it's going to fight - STOP - and take a step back and be cautious on how much force you apply - Kroil or similar is your new best friend - get the engine to (WARM) not cold or hot - and gradual turns CCW & CW - alternating and extending the turn CCW farther as you back it out (using the CCW / CW) method - it will come out and if it lets go - (easy out) is your next best friend - the problem is - and where the techs (mis-step) is trying to force the plug threads past the corrosion - it will the seize up.

Kroil is the bees knees. The reactor coolant pumps at the nuke I retired from are four inch diameter bolts that take a 6 15/16 inch socket, weigh about 140 pounds each, and take an XLT50 head (50,000 foot pounds) to break loose. We use to pour Kroil down the heater rod holes in the center of the bolt to start soaking the threads for bolt removal. I keep cans of it here at the house.

Yes - I like it - it works great but STINKS - I hate the smell of it.

Cool Beans!

I've never visited a nuke generation plant but would love to tour one up close.

When I stationed at NORAD CMC, I remember visiting the generator area. 6 very larger diesel generators lined up pretty as you please, with cat walks up near the top of the engines. 2 running, 2 for backup, and 2 down for overhaul. (Nothing like a nuke power plant in scale)

I remember seeing two men up on the catwalk with what I would describe a very large ratchet, both men working it to remove the head bolts, there was a large electric hoist installed onto a big I beam mounted into the top of the granite ceiling that lifted/moved major parts,

I remember looking up and seeing copper infused into the granite ceiling. When I inquired about it, one of the mantenance crew told me that one of the previous generation of generators had caught fire when the fuel line was breached and ignited when the fuel hit the hot exhaust manifolds, that they had to evac the area, seal the area and pull the air out the generator area to put the fire out.

That copper was what was left of the electrical mains that powered the entire complex. This incident happened years before I arrived for duty there. The facility was still mission critical back then, before the fall of the USSR and the end of the cold war.

I found this 9 year old 3 minute video, and those generators look just like the ones I saw back in 1976. Same light blue engine, green fuel rail and lines, and the same black catwalks. The video gives you an idea about what's there and even shows the generator room. I grabbed this image from that video. And I remember that row boat in the water reservoir!

This picture is taken from the control room that overlooks the generation plant. It is behind glass and actually very quiet until you open the door. The squeal is deafening without headgear.

The place is an engineering marvel!
