just wondering how many miles can a 5.9 motor have on it before it dies , mine has 122,000 on it , an running fine

 

anywhere from 1 mile, to 1,000,000 miles. Depends on how its used, and tooken care of...

These on average will hit 200+ without any problems.

 

I've seen quite a few guys on here with well over 122000 miles and I'm hoping for another 100000 at leastmyself. I have 95200 on mine right now, and I'm hoping for a lot more.

 

bought my 2000 with 121k on it, within a couple of weeks it had mobil 1 in it. put 65k~70k on it and it was running awesome when I sold it. I had the heads off for a head swap and the cylinders looked awesome, very little ridge on the top of the cylinder and still showed a nice cross hatch in the cylinder bores.

 

My '01 has 268,000,no problems out of the motor at least.I did the timing chain at about 160,000,and it had alot of slop in it..something to consider.

 

Mine's got 134,xxx. Runs like a charm. Only slightly major problem I have in the exhaust manafold leaks it's got. I have some flowtech headers sitting next to me going in sometime next week.

 

150k & one of the valve springs broke taking out a valve & pushrod so I went for a rebuild. Strange, I don't race the motor, I don't tow & the spring broke while coasting through town.

 

when my magnum blows...that will be the place where a hemi goes

 

Mine has 187,000, bought my '95 1500 on June 1996, runs good.

 

I'm just about to hit 139kits running just fine.
