Clay at RiffRaff has OEM BABY forged rod rebuilds.

It's NOT the PMRs.

EDIT: *IF* he even had them.

 

Sorry to hear this. I hate reading about these things, it makes me nervous as poop and I think about taking off the tuner and going back to stock injectors.
I wish it were true the forged rods never blew. I think someone might have a bit too much faith.

 

They are NOT bomb proof by any means. There were several on here running less HP than me on forged rods with scrap metal blocks now.

 

But he read it on the internet....
It MUST be true.

 

that is just bad. i dont like to see a good truck die.

 

Very funny... y'all take me wrong!

Guys, I don't think that PMR's are the only problem. PMR's, IF the OP's are PMR's, just aggravate the problem. I'm sure if anybody tried hard enough, they could break anything! I'm just saying that if he had PMR's, it would explain his mess pretty well. As for the forged rods breaking, I'd have wonder about their tuning... from what I can tell, cylinder pressures seem to dictate whether or not the motor lives. I know tuning can determine whether or not PMR's survive... to screw up a forged rod motor, I would think there'd have to be some poor tuning involved. But what do I know? I just go by what I read... then I call up Clay and find out what holds water and what doesn't.

 

I don't know much either. But I know enough to know that most of that is still all wrong; or at least only half right.

 

Just curious:

Did you normally drive around with the +80 tune, and tow with the +40 tune?

When did you install the DP, and did you ever have the tunes updated?

From what it sounds like, Jody updates his tunes regularly. But I've never heard any specifics beyond that, like if it's a set schedule, if he keeps track of what updates are made when, etc.

 

FWIW, I start up, drive, idle, etc in my hottest tune. Good or bad, it's been working for me. I guess I should knock on wood now...

 

Real sorry to hear about your unfortunate luck. Sounds like you took care of your engine as well as the rest of us. Sometimes stuff just happens and we never find out why. From time to time it's possible to tear down the engine and discover the cause of failure but many times it's just speculation really. Did you get your oil sampled by any chance? If so, I would be curious to see the report.

If you decide to tear down the engine, take lots of photos and notes about what you saw and where. I would look at the top side first and see if any part of the valve train is compromised and keep the parts organized by cylinder. Then later on when you get to the bottom end you can look at the valves and pushrods more closely if you suspect something weird.

Same for the injectors, keep them organized in case you discover something weird on the piston tops etc. I'd also be curious about the cooling jets and if any of them are missing. Good luck.

 

I usually drove around with the 80e setting. Thats what it was on last night. I got the tuner from jody in 2007 and never sent it back. When it let go I was just driving easily home.

I'm not sure if I'm going to put another 7.3 in or fix up the body and do a cummins conversion. Going to do same calculations tonight.

A Cummins conversion would be sweet! I would take the motor apart first if you can and find out what caused it... if it was because of PMR's, then I'd drop in a built-up 7.3L and be done with it. I've got 303K on mine (forged rods) and I have yet to kill it! My live data checks out great and the only leak is an oozing oil pan seal.

 

just curious, what do rebuilt 7.3's go for?
