I was curious too see how many miles do others have on their Blazer, Jimmy ect... I am closing in on 250,000 and I did find out it is the original motor I know there are many of you that has mine beat... Who is currently at the top looking down for us too catch up I have a 98 4x4 Blazer... I suppose I have rather low miles considering it is a 21 year old SUV

 

I have almost 140,000 on my (as far as I know original) engine. The transmission was rebuilt a few years go. The rest of the drive-train and other components are original.

 

115k, all original. I picked it up at a local county vehicle auction for peanuts, it's an 04 2wd 4dr, used by the local health Dept for inspections.

 

Mine has 291k, but I don't know for sure if the engine is original. I think it may have had a valve job at one time. Pretty much everything else (except the body) has been replaced by me.

 

I've got just over 270k, passed it last week before killing the transmission, no major engine work has been done yet.

 

325...km / 202...miles

original motor/trans

 

199k on my 96 all original drive train.

 

There are already 2 or 3 threads on this subject. Here is one of them:
