Engine Failure at 18,000 mi

[dphorton]

I had rhe Engine fail at 1800 mi. I am surprised as all of a sudden it started pinging and lost power. Unit is currently in Prescott AZ awaiting new Engine. Anyone ekse had rhis issue?

[dphorton]

Sorry forgot 2016 Georgetown 328.

[kenandterry]

Tell me this is a warranty issue. 1800 miles? Really?

BTW....Your make and model are in your signature.

[dphorton]

Yes it is covered under warranty but only 18,000 miles. Waiting for a new Engine.

[kenandterry]

I saw 1800 in your story versus 18000 in your title.

Either way.....I’m hoping it’s a warranty issue. Have you heard yet?

Catastrophic failure of the V10 is pretty rare.

[dphorton]

Sorry for the mistype, it should have been 18,000. I agree that I was surprised when the Ford Dealer told me I needed a new Engine.
So waiting for new Engine to arrive as the old one is out. Don't have specifics on what happened internally. Waiting to hear that information.
Thanks for replying.

Please post what caused to the engine failure. Lots of V10 engines out there.

[Cold Lake Kid]

I have the Ford 10 cylinder in my unit as well.
I too would like to know what happened.

X2 !!!
Maybe a Great thing that they are willing to replace it,,,
and not try to repair it !!!

[dwreefs]

Ejected a spark plug maybe

[dphorton]

Hi All,

I found out today what happened. Two Cylinders ingested the Spark Plugs, causing the breakage of both Pistons and ruin the Engine beyond repair. The Service Department at Gaplin Ford Truck and RV in Prescott AZ have never seen anything like it before. So waiting to hear about the new Engine arrival and installation. I did joke with them about don't use the old Spark Plugs please and I was assured they all will be new ones.

[W5CI]

It used to be quite common for that type of engine to Blow out spark plugs that came loose but I have never heard of and engine Ingesting a spark plug much less two of them at same time. Pleas keep us informed

Can't believe in this day and age this is still a problem for Ford. My '97 Expedition V8 had a plug issue with plugs blowing off cuz some knucklehead Ford engineer didn't think that the plugs needed more then a couple of threads in the head.

BTW, is Ford still recommending 5w20 for a V10 pulling a heavy load? I can't imagine the bearing wear with such a thin viscosity.

So you seem to be smarter than the FORD engineers,,,
what oil would you recommend ???

This is a known problem with 5.4 and 6.8. too few threads in the head. 4 threads VS 8 until 2003, at least in the 5.4.
I never spit one out in my 2001 lightning because I was religious about checking them. I can't believe a brand new v10 is spitting out plugs. Good that your getting a new motor. Make sure you keep tabs on the install.
Post some pics of the carnage!

My neighbor,,, a Great old Mower machanic,,, once owned a Garden shop,,,
Tells me you should never change plugs with out using anti-sees grease !!!
I have never had any engine spit out a plug !!!

I thought that I would pass along what I found out about my Engine failure. First they told me that Two of the Spark Plugs disintegrated in tow of the Cylinders. Then when I went to pick up our Motorhome last Friday I got the actual Work Order. I says that the Exhaust Valve on Number Two Cylinder went through the Piston and the same on Number 3 Cylinder. They could tell me if the Spark Plugs cause the Exhaust Valves to become Jammed by the Spark Plug pieces and hit the Pistons. Anyway I will never know for sure. That is the best I can do. The new Engine runs better that the original in my opinion. We will see how it all works out. Oh by the way I was wrong on the mileage. I only had 17,028 on the Odometer.

So it wasn't the spark plugs after all. Possibly a couple defective valves or valve springs or valve sorting retainers... you'll never know for sure.
Good to know they stood behind it and covered the repair.

Regarding viscosity... I'm not an engineer, and don't claim to be smarter than one... but I have read some things about it and I'm pretty sure viscosity is just a measure of pourabilityand really has nothing to do with wear of bearings except... a thinner oil can get to where it needs to be faster especially at lower temps.

5w20 synthetic is specd in some modern heavy duty diesels... if it van lube those bearings it van lube the comparatively lightly loaded bearings of a high revving V10... low end torque hurts bearings way more than high rpm ever can

[Mainframe]

A piece of porcelain came off the plug, got under the exhaust valve and held it open so when the piston came up they crashed and destroyed each other. Tech installed a long block and off to the races again.

In 1994 There were 300 accords came through with valve springs that were never heat treated properly, most of them made it 4-500 miles snd scattered, all they had were short blocks available, installed all new valves and springs and the cars ran fine.

It happens to all manufacturers.

They just fix them and move on.

My 2010 V10 used 5w20, my 2016 V10 now uses 5w30. The 2016 runs quieter and uses no oil between changes at 12,000 miles, the 2010 used a little.
