This is only the fourth CTD fail we've seen in six or so years, but it's interesting that all of them have been modded in some way and all of them have not come in with a Mopar/fleetguard/Cummins oil filter. This one has an EZ edge on it and they do have a post turbo pyro. Said it never went over 900. Sounds like this one has a rod knock rather than a scored piston as the noise goes away after oil psi builds on start up.

 

what cylinder is making the noise? post turbo and never over 900? were they pulling?

 

I bet you find piston oil squiter(s) in the pan!!..the shoulder they put on the plastic crap breaks off and the whole thing jumps out of its home!!!!!!!!!!!!!!

 

How many miles does the truck have

 

Truck had 85K on it and it was a very nice rig, very well taken care of, and yes, they were pulling a fifth wheel but we didn't get to see that. Said it was only a 30 footer. They're hauling it back to Texas so I won't be breaking it open. Couldn't tell which cylinder because it would only make the noise until oil psi built up. I'm sure the noise was there, but couldn't pin point it over the nomal noise. Cancelled cylinders and listened to the block with a stethoscope and honestly could not hear a difference anywhere. I did pull the oil filter off and poured some of its contents on a piece of plex glass and you could see the shimmer of metal particles in it. Most likely bearing as the magnet didn't seem to affect it.

 

LOL , I think Thumper has a really bad taste about plastic oil squirters that are use in the engines, now I am not gonna say they are crap , I dont care for them either.... but the number of failure of the oil squirters are very few. I have done a number of engines and can only remember one failure and it was coupla weeks ago in a 4bt engine. anywho at least now you can put the steel oil rail piston coolers in the new blocks or 02 blocks and newer. the new 600 do come with them ..

 

I kind of tend to not believe that...that's silly if they expect people to believe that stuff.

 

So.......what brand of oil filter was on it?

Even it the pyro didn't go over 900*, that is still living on the edge. If you decide to run with temps that close, it would be a good idea to have the pyro calibrated on a regular basis.

 

i thought that from reading different forums that 900F post turbo was the equivelant of 1400F pre turbo which is way too hot, # 6 starts melting away.

 

It would be 1200 degrees (their is a 300 degree diff.) ..this whole article shakes me, i have a 98.5 w/ 81k on her and i love pushing the envelope...i too would love to know exactly what the problem is and how hard he ran it.

 

Hmmmmm... Wonder if it was a Fram

 

No fram this time. It was a NAPA filter I believe, the one with the blue print on it.

 

are we all stabing at this or dose someone have this apart to see what actually went wrong???!!!!......
