Hello, I am new to this forum but not diesels.
My background has been diesels and hydraulics for the past 31yrs.
I look forward to meeting all of you and helping out.

Welcome to the site it's great to have you here

Thanks you

We will see what happens when a 6.7 guy posts his regen valve shake and gets my failure analysis essay. It has caused rioting on two other sites. It is dead on accurate gets people who don't have it extremely insecure it will happen to them and they get mad like its my fault the resale is falling out of the bottom like what happened with the 6.0 and 6.4
Oh well 31 yrs in diesel and hydro with no lies and almost 0 comebacks, I'm going to continue to do good work, write it up like it is and try to help those that are in need of it.
Glad to be here.

You lost me. Maybe it's too early for me. You found out why the shake in regen?

I was referring to the regen shakes some 6.7s experience.
It is caused by some engines having valve guide to stem clearances that are too tight.
During regen, the exhaust valves get blast furnaced during the exhaust stroke.
This heat causes thermal exhaust valve stiction.
This stiction is not a seize. It is a stiction.
The valve geometry is a strait up and down.
The piston actually impacts the valve knocking it free from its static state.
Due to the geometry used this event does not put lateral force on the valve, so this collision is not immediately catastrophic.

Most that have stem clearances that are too tight will develope the the violent regen shakes in the 3k-20k range.

Ford's first attempt to rectify this was to remove your cab and left head. Then the valve stems were to be cleaned and reinstalled. Trucks would come right back after this was performed.

Anytime back pressure exceeds atmosphere, exhaust gasses will escape vent right up those exhaust guides. These gasses will leave a film. This is normal for all engines.

Some heads came thru with guide bores that created stem clearances that are too tight.
The exhaust valves used can be purchased for $7 and change from a vendor that sells for 10 .percent over cost.
During this blast furnacing of this valve with temps reaching over 1400 degrees it experiences thermal expansion. This thermal expansion causes this stiction.

There are over thirty cases I'm aware of. Many trucks have been put thru the Lemmon law process.
Ford went from the stem cleanings to issuing a TSB saying if a customer came in with this condition to put the TSB in the customers hands stating it is a normal condition. This is after they had made statements engineers were aware of the problem and we're working on a fix and after the stem cleaning campaign.

There is a case on the diesel stop and ford truck enthusiast. The repair order has the mechanics notes stating they were too tight and that was on his bench at room temp. backing up my failure analysis for those looking for corraberation.

Again fellas I mean no harm or anything like that at all and hope I'm not viewed that way.

 

[Jomax]

So, what's the fix? ****** it?

I'm At 25k Never experenced anything Like that. Hopefully I'm lucky lol.


Also, why are you banned on some sites lol.

I was suspended after I "snapped" at 3:45 AM and partially spelled out an expletive after the mod allowed three or four guys shred me for about 6 hours.
There was oppososition to that move. I have received many emails offering support. At least one thread was started asking where I went and conveyed wishes that myself and my family are well.
Autoguide received many emails from members and at least one vendor expressing concerns over how the situation was created to run me off. Autoguide is owned by Vertical Scope. I discussed with them on the phone the situation. In the end their desire to follow their mission statement that " the interest of the OEM vendor trumps all but would " make sure wings were clipped equally" referring to my question how the moderator allowed the others who were attacking me to grossly violate these rules they referred to when I had partially spelled out the expletive.
I did not come over here to further upset some but to rather explain what was happening mechanically and offer suggestions as what to do when Ford would refuse to acknowledge the problem let alone not fix the truck.
I have had some say, I was saying the sky was falling and calling me Chicken Little. I'm not saying the sky is falling, despite that's how many owner's feel when it's their truck and ford is unwilling to take ownership of the problem and rectify the situation.

I thank all that have welcomed me here.

Sounds like you suffer an inability to suffer fools.
Hope you can stick around and contribute!

 

[Jomax]

sounds good Nick, all the other Forums are lame anyway. looking forward to more good info from you. i assume for us to fix this issue, means getting rid of some epa parts

 

[mandkole]

is this that 6.7 rattling/shuddering/clatter during regen that a handful of dudes have 45s on their foreheads about??

I like your analysis ...welcome!

 

[Maryland dieselnick]

Thank guys.
Regarding doing the D word, I remember the air, water and soil conditions in the 60s and 70s and never want to see us back there. In addition pros get caught get crucified. Two things I don't want any part of.
If your truck has it, the key is getting it to a dealer that knows what is up. They need to yank the driver's side head, get it on the bench and THEN call the hotline to say," we pulled the head and the stem to guide clearance is too tight. We will be installing a new head.
It does not end there. The tech must relieve the springs and physically check that this new head does not have the same clearance issue as this is not a straight across the board problem, so the new head my or may not have the same clearance issue.

As disturbing as this component quality control issue is, what is more disturbing is how Ford has been handling it. Some are getting year newer trucks plus 200k warranties and others are being left to twist in the wind.
