Who has the highest mileage 3rd gen??

No one cares.

 

Saw this today. He said it has just seeped a little from the timing cover since 250k

 

140000 on my 2017.

 

Still the only reason I check this thread is see if @bigoldbeef updated his mileage and its kind of fun to see people who can’t read waste their breath and get shamed for it.

 

I think it’s great seeing all these 3rd gen’s starting to rack up some big miles over the years , I’m planning on keeping mine for a long while yet so it’s cool to see people having some long term reliability , helps offset the posts about burning valves and leaky timing case covers

 

I’m at 428k. Truck still runs but cylinder head is shot. Cylinder 2 only has around 40psi compression, bad exhaust valves.

I can drive on the interstate all day but shortly after I start putting around at 15-30 mph it goes into limp mode.

Trying to find a solution to limp it along further.

 

If my truck makes to even HALF of those kind of miles without major engine work I’ll be happy

 

yeah it’s been a great rig! I’m surprised it made it this long with all of the abuse. It’s gotta have around 17000+- hours of run time with idling. Wish they had engine hour meters.

 

Would certainly be interesting to see a tear down of the engine, the bearings, cylinders, and so forth. Sounds like these engines should go 600k+ miles under less strenuous conditions.

 

I wouldn't be happy unless I made it to at least 300K without needing major engine or trans work. That's one of the pitfalls of having owned a 5vzfe.

 

Why not just replace the cylinder head and keep going?
