I am looking into buying a 24 valve cummins and I was wondering if there was any real realiability issues with them. I used to have 95 12 valve and I never had a bit of problems with it. and if there are any issues how hard is it to counter those issues? thanks guys

 

53 block has a bad habit of cracking, the lift pumps are notoriously bad for going south, and when that happens you are going to lose the VP44 shortly after.........

 

There is some issues with em but no more then any other trucks out there and fewer then some. I personally wouldn't have any other truck myself though.

 

Logan got most of em down. If you buy a 2000 or up you're pretty safe as far as the 53 block. When you get it I would go ahead and upgrade the fuel delivery to the injection pump (Fass, Airdog, Walbro) and get at least a fuel pressure gauge.

 

Lift pump, injector pump, some 53 blocks, dash cracks.

 

Front ends - balljoints, steering boxes etc. can be troublesome as well (as in any truck).



But the biggest concern is the lift pump, and Injection pump (VP-44).

Before you buy a truck, make sure you check it out - have it scanned for codes, and try to check the fuel pressure from the lift pump. The 24Vs are entirely different animals than the 12V's.

 

WOW all the problems I had with my truck whenI got it!! But I love the truck and will never get rid of it!! all easy stuff to fix and EVERY ONE on here will help you every step of the way (The only thing I have not lost yet is the VP44) Good luck with what ever truck you pick out!!!

 

Mine is on its second VP44 now acording to Dodge. Had one put on at 68000 and always had fuel PSI over 10psi at WOT, died at 124000. The rotor seized in it I believe.

Can you get a report from the dealer that tells you every time the truck was in for service, and what was done?
