CM2250

The ceramic plungers have been recalled for a. Steel plungers I think or some other material. Been hearing stories of those upgraded plungers not lasting either

 

My 2013 isx was upgraded before the recall , I've got 650k on it now with no problems.

 

Nice! I’m still hearing in certain circles to rebuild the pump around 300-400k miles, even on the updated ones. But I’m not a mechanic per say, but these guys are smart! And one owns a shop with his fair share of traffic

 

I have the 2350, I upgraded to the latest version, hardened and redesigned roller pins, gotta get with a parts guy that isn't stupid though, the kit is a new pump, gotta order everything individually.

 

I've heard of people just going to the old 2 piston fuel pump to fix that issue.

 

3 piston were the older pumps. Obsolete for awhile now. Everything is 2 cylinder now.

We have had good luck with the updated tappets and plungers. Not seeing blown pumps and windowed engines like we used to.

 

How's the oil consumption going? You doing samples?

Samples will identify the EGR cooler and fuel pump starting to wear out.

Talked to a guy that bought a truck like ours and lost the engine to EGR cooler failure.

But when you get the whole story, he drove it like 5,000 miles with considerable coolant loss. Just kept adding gallons.

 

I'm still confident the 2 piston pumps are the old non ceramic junk pumps.
@Justrucking2 may know.
