If it's at 100k, it NEEDS to be done...the timing belt is a ticking time bomb right now, and is waiting to go-and that's a bad thing...

 

he is def. right about that. on lostjeeps.com there are a lot of horror stories of belts failing and causing a laundry list of additional problems. better to get it done and dodge a bullet

 

Way back when, I saw that some company had a gear-drive contraption to replace the timing chain for some gas V8s (seems like for a smallblock Ford). Anybody do similar for these? I've just never been a fan of the whole timing-belt idea.

 

Haven't seen anything about it for these...and as big of an issue as the TB's are, someone over on lost would have come up with it or found it by now.

 

yes they would have. the guys on that forum are obsessed with everything about these motors. everything i have learned about my libby diesel has been from the lost forum.

 

Update!..... no update. : between tuition, rents, etc, etc, etc, the Libby's still parked for a while. maybe later this spring or summer we'll address its issues. T-belt, probable new turbo (I think OEM again, if the GDE is fixed-ratio.... I like the exhaust-braking action when I get off the go-pedal, and my kids do live in the mountains.)

 

I have an 06 liberty diesel that my wife drives is there an actual delete kit i can do for it? I have the GDE tuned on it cant remember which one i did but i would like to know if i can get a delete kit??

 

There's no actual delete kit...most people either run the GDE tune, which disables the EGR unless it's an emergency, or the SEGR, which was a custom made kit that completely disabled the EGR, but kept it from throwing a code. I forget who was making the SEGR kit, but they aren't making any more, so now you have to look for a used one.
There have been a few that "self-deleted" the egr, whether it was pulling the entire assembly off the side of the block, and rerouting the coolant hoses, and blocking off the exhaust and intake ports, but I think most have simply blocked off the intake and exhaust ports, and left everything else in place.

 

Thats mostly why i got there tune was cuz they said it shut down the egr but is there anyway to tell that it actually has? The reason i would like to do both is cuz my brothers truck was shut off but not deleted and then we ended up doin it and it made a big difference in the egts and his exhaust sounded way less restricted once it was blocked. What do yal think?

 

Update..... This time, there is an update. Kids have moved back to Texas (son and the infamous blue RhinoCharger in the Fort Worth area; daughter and the broken Jeep to San Antonio) Jeep's central turbo-shaft sheared (WTH causes that on a system that doesn't exceed, like, what.... 25PSI, or maybe even less?) The guy told me that all the broken metal went down the exhaust, rather than forward, towards the intercooler. For simplicity, what would be entailed in a block-off of the EGR system? A piece of sheetmetal sandwiched between the exhaust pipe and the EGR tubing? Unless there's some really dreadful plumbing (I haven't looked and seen how it's made) it seems that would be the most direct approach, "check engine light" or not..... Next question: If we did that, would the computer be confused and angry, and then not allow the engine to run correctly? ------all three pieces of my Diesel knowledge are most applicable to a 12-valve P-pumped Cummins 6BT, and I pretty much don't know jack about a VM 2.8L.
