the only way I'll get rid of this thing is if the insurance totals it out.

 

I put every spare penny I make into mine, the only way I will lose it is if someone steals it.Hey Drew,just wondering.I know part of what makes the big diesels run forever is that you can replace all of the internals and its good as new. Can we bore our cylinders and use piston sleeves if we need to rebuild a 5.9? Would it be worth it? When is it time for a rebuild? Sorry bout all the questions, Thanks buddy

 

i think they are pretty easy to rebuild I think cummins says 300k is the estimate for life span.

 

those are the kinds of answers i was looking for...... glad to see how many people said they'll keep it till it falls apart.....

thanks for the intrest in the topic

 

on our engines, if the engine ever needs a rebuild it mostly involves the crank bearings. Thecompression rings on the piston are stout enough you would have to realy trash the engine to dammage them. they have the same keystone design the OTR truck engines use.

yes, the ISB block can be bored out, Tritons engine is. but whats the point unless you have substantial damage like he did. Also our engines are too small to have sleeves.

even though Cummins has stated a 300K life span on these engines, there are quite a few on the road to this day sporting well past 5-700K and a few that have gone past the million barrier.

 

Wow, 1 million miles. When do you know its time for a rebuild? Whenit craps out on ya, or when you think itstime? Good info, thanks Drew.

 

mostly when you start having excessive blowby from the vent tube, compression rings. Rod knock is another, when the crank bearings are gone.

 

More good info. Thanks, Drew!

 

I know 2 people that have 600k+

 

I am going to see about trading mine in at about 75000 miles so 2 or 3 years. just for the fun of it.
