Melted #6

[sick_ram]

Well got the real word on my truck today. The dealer had told me that all six pistons were melted. Had a friend go and check it out because I live 400 miles away from where my truck died. And come to find out it is only number six that was barly even melted. Dealer said the the valves were all pepperd and, truly the head was fine no damage. I think this dealer wasw trying bend me over. Still going to put a new engine in it though.

Well I think it could have been better but still could have been worse! At least you have a friend near by so he can make sure the dealer is being honest! Good luck SR.

 

[WUnderwood]

yes, you need Lady Luck on your side!

Did you have gauges? I see you have 600 hp Do you know why it got so hot?



Luck to ya

sounds like ....

ker ching to me... ... I mean - this is out of your own pocket :--)

 

[sick_ram]

Yes, I do have gauges. My EGTs were only 1300, and I only held them for about a qaurter mile. And I dont really run it that hot very often so not really sure why it burned up. I could see it happening it I had run that temp on a regular baces.

Where's your probe loacted, before or after turbo?

 

[mattymac]

I wonder if there was an injector issue in the #6 hole? and it was getting more fuel than the other cyls? I know #6 runs the hottest but alot of us run hotter and longer than that?

 

[CLAYTON]

1300 isn't really that hot either.

 

[mattymac]

thats why im thinking maybe something went wrong in that cyl. in that particular run.

 

[RankRam]

Plugged cooling nozzle???

 

[Diesel Power]

or too much timing

 

[mattymac]

or too much timing

Wouldt that do damage to more than just one cyl?

Sounds weird? to many variables. I run my truck around 1300-1400 daily to pull a couple grades, and they are long grades. I've got 33K YTD and have not melted anything and my engine runs fabulous. Not sure if it matters but I am a Powerservice/ MMO ***** and have a few other things I mix into the fuel :-laf but I'm just as baffled as everyone else, these engines can take much more abuse than that. Only thing I'm not clear on is your Pyro probe pre or aft the turbo? makes a huge difference, mine is pre turbo and I hit 1300-1400 daily with no problems.

6 would burn first. But at 1300... ..... those parts shouldn't degrade below about 1400 sustained. Where exactly were you getting EGT's from?

600Hp is quite a bit of heat, sorry to hear of your misfortune!

My probe is just after number #3 exhaust port on the manifold.

Yet we are all still assuming his gauge was accurate.



I've had several gauges reading horribly low.



Just a 10% error at 1,300 puts you at 1430.



Not to mention lag on the t-couple, if it is touching the otherside of the manifold, if it's too close to the head, or put in a web of the manifold.

thats another good point

This all sucks for you dude, I've been following your threads and I am sorry about your misfortune. There are many threads on TDR of guys pulling grades with stock trucks and seeing 1300+ continuously. I gotta think there was a problem specific to #6. 1300deg. just isn't that hot!!

 

[sick_ram]

What Diesel Power is saying might have some fact. A truck with 1300 deg stock might be different than 1300deg with a truck that has lots of timing. But still About a mounth ago I was on a dyno with all kinds of load on it running 1400-1550deg and the boxes all of the way up, and held up fine.
