My cost to replace my 6.6

[spongebob]

In 2021, I replaced the head gaskets (plus new factory head bolts, fuel system banjo seals, etc) in Lil Red for about $300. I added ARP studs, a new water pump and new injectors to my 2001 GMC head gasket project, also in 2021. That wound up costing about $3300 total, if I remember correctly.

The mileage that your original engine has wouldn't concern me if it's not been abused. In fact, I'd rather trust it over than the quality of a questionable rebuilt engine. One question I've yet to see answered concerning a Duramax reman is "Did the engine need to be bored?" I've yet to see a cylinder bore on these engines that was worn. The cylinder bores are induction hardened at the factory. Boring them removes the hard layer.

all I know is what they say..and in todays world you cant believe anything..I was thinking when this engine is delivered to look at the cylinder
walls from under .you should price injectors today some are going for $500 each..I provided a link to the injectors Ill be going with, they are rebuilt by
Bosch trained techs..fuel lines and glow plugs for $2500 yob got a good deal those days are over.

The LB7 reman injectors I installed in my 2001 GMC came from Kennedy - $2200, if I remember correctly, was the cost for 8. I also installed new injector fuel lines at a cost of about $650 and ARP studs for $650 - plus misc consumables. I'd have to dig out the receipts to be accurate on prices, but this is in the ball park. I actually wound up not installing the new water pump, so that cost isn't figured in. I also could have cleaned and re-used the fuel lines if this had been a budget squeaker - saving another $650.

I re-used the injectors and injector fuel lines when I did Lil Red, because the engine only had about 8,000 miles on it. Lil Red's heads didn't need to be decked, and I installed factory head bolts when it went back together instead of ARP - that saved $500. Glow plugs can be tested before they're re-installed. No need to replace them if they're still in good shape.
