Also they have 2 different piston configurations, thats why the 2 different glow plug lengths.

 

The .047 difference between the 2 glow plugs are 1.2 mm as posted by Ford, so if a proper glow plug has 0 clearance (which I doubt) between tip and surface of piston using the wrong one would make a .047 inclusion in the piston. There is no way in hell this contact would compromise the compressive clamping force to cause a head gasket failure. I have seen over the years several gas engines that swallowed things through the carburetor embedded themselves in the top of the piston before being blown out the exhaust port. None of them resulted in HG failure.

So you can see they didn't shatter, shear etc. etc. they just bend. The pistons had round dents all over the tops of them. So I think they would hit and move around a bit with each hit. Which also explains how my truck was a lot noisier running than the new motor with correct plugs.

 

Oops, Oh yeah. I had this discussion with a buddy of mine and we were talking Ford vs Chevy. It was the Chevy Duraslap that had the aluminum heads. Sorry.

 

I have just finished going through 4 years of repair invoices. I brought the truck in 3 times for no start issues.

FEB 2008 - First no start, they determined it was a bad "stater trigger wire" replaced and tested ok.

MARCH 2008 - Second no start, they cleaned wires and grounds and tested ok. I also mentioned the truck seemed less powerful but it "tested" ok despite my comments.

DEC 2008 - First head gasket job. Tech said heads were within spec and no machining done. They installed ARP and ford gasket.

APRIL 2010 - Third no start, no codes. FICM syn PID out so replaced FICM and Cam Sensor Harness.

JULY 2010 Heads blown again. They offered a reduced price to re-do them. Say heads are fine again. Install ARP and Black Onyx gaskets

DEC 2010 - No heat and same symptoms of first head gasket blow. Tested and they are bad again. I talk to a performance shop and get a new motor installed think that that motor was cursed.

I don't see glow plugs replaced or mentioned in any repair. There are other repairs too but these are the ones related to "no start" and the head gaskets. For instance the ICP sensor was replaced 2 times over that time span as well as the cam sensor, oil cooler and EGR cooler. The EGR cooler was the first time only. When would you replace the glow plugs as standard procedure on a repair? Wouldn't the tech mention it in the invoice? I had one repair done under a 3rd party warranty shortly after I first bought the truck used in 2006. I don't have any paperwork on the repair, but I don't think it involved the glow plugs. They did a bunch of stuff but the biggest repair that time was replacing the power steering gar box I think.

I am starting to think that maybe the truck was bought with the wrong plugs in it? But they don't look very old do they? I'll talk to my service rep supervisor and see if they have any record of the glow plugs being replaced by them. If not, then I will apologize and focus on the dealer I bought the truck from. Someone must be accountable!

 

you need an OASIS report IMHO

 

Side note: "etc" or et cetera means 'and other things' or 'and so forth' which in this case would include 'bending'.

Those are some wild pictures. When I buy parts from my local slinger I always make him double check with my engine's number because mine, like yours, is right in the weird gray years...

 

Yea, I am learning a lot about diesels lol it's been an expensive lesson but this forum is a great help! I just assumed that the tech etc. at the dealer would know more than me and install the right part. But if they didn't touch the plugs then it must be from the NON-Ford dealer I bought them from. Would a NON-Ford dealer have repairs show on an Oasis report? Or just if they used warranty to cover it?

 

BTW how do you get an Oasis report with FTE? Does it matter if I'm in Canada? I had a CARFAX done on it and it showed no accidents etc. but didn't give info on repairs.

 

I think the above three incidents are pretty alarming! To not deck the heads is criminal. I know some techs will disagree but I trust a fresh deck over a tech with a straight edge (yes, I know there's more to it) some techs know what they are doing but I bet most don't. Always deck the heads anytime they are off, especially because decking the heads is only going to cost a few bucks more (relatively).. Saves a lot headaches and/or troubleshooting down the road because with decked heads at least you can rule out a potential cause of problems (problems which in your case might easily be attributed to warped heads....) I bet they even reused your TY bolts too!

New motor? Whiskey Tango Foxtrot!?!?!?

 

Ford won't deck it's pass or fail so if your pro active and the dealer will tie up a lift for 2 day definitely take them out for inspection
I wish they would do better ,,
an OASIS is getting hard to come by but the dealers are your best bet

 

Ford wont deck heads? (liability)? What's the tolerance? Do they just replace instead of machine?

 

"New motor? Whiskey Tango Foxtrot!?!?!?"

Huh?!?!? I don't get it lol

Checked Build Date: 07/03

 

I don't know the tolerance theyspec ? but the max u can mill is very little ;; but ford doesn't have the capabilities to machine them //or actually check them properly ,, so yes they replace them if they are obviously out of the straight edge they use or if a crack is visualy detected

 

Wow, it's interesting how different the "industrial diesel" (CAT/Deere/etc) vs. "passenger diesel" (Ford/Dodge/etc) is. The passenger side seems more cut-throat and/or unwilling.

Rep'd ya!
