Crankshaft Replacement

Could always plastigauge the mains and rods. Only thing I could think of.

 

I’m sure you can have a machine shop magma flux to check for stress cracks and mic’ed out I guess not sure. Never heard that one before. Why on earth would Crank be damaged?

 

Depends on its shape and what your trying to do. If your trying to build another million mile motor it might be worth it. Plus you get the ECM, turbo, wiring harness and etc. if you do get a long block, it might be worth pulling the head off at the cost of a gasket and some labor to check the liner height. Heard some true stories of liner heights on new long blocks being mismatched and etc

 

I agree.
Unless your bearings seized or connecting rod broke. How would the crank be damaged.

I think the shop is trying to upsell you something you don't need.

I was in a Cummins shop. I had the overhead done because I had a loping idle. I couldn't get fixed. They said I had a crack in the fuel filter housing. They changed that.
Still had the problem.
I asked the tech at Cummins if there could be any O-rings in the fuel system other than where the filter spins on.
He said no.
Than the Shop Forman (salesman) came over and starting to spew why I should just put a crate motor in my truck, instead of Overhaul. He implied my problem is most likely head related.

When I got home, I got my hands dirty. I didn't know the fuel lines had O-rings where they attached to the fuel filter head. I found this out as I was installing the Fass system.

My point couple O-rings could have saved me $350.00. Not to mention the crate motor he wanted to sell me. Some shops like to maximizing the profit. Not having the main focus of helping "you" the truck owner.



Good luck.

 

Now that makes sense. I’m sure you have seen Rawze on Utube. He may know a bit about all that and the economics of it all

 

1.6m miles, it would be wise to pull the crank and have it checked.

 

That’s a great story!! Perfect example of how some so called reputable shops try to rip you off . I love it . Be tempted to go back and politely educate them on this. With a” Thanks for your help anyway.”

 

I wouldnt do that on a longblock, it'd probably void your warranty.
