Looking at buying a 2001 Chevy 2500HD with the 6.6L. After checking the vin, looks like the following work was done:

belt primary acessory drive replaced - 30667 miles
injector, fuel replaced - 50378 miles
replace all 8 fuel injectors - 73173 miles
plugs, glow (diesel) - Left - replace - 81572 miles
replace fuel filter - 85590 miles
plugs, glow (diesel) - Left - replace - 85590 miles

I am wondering why the glow plugs were replaced so close together and only on the left side. Is it possible that the fuel filter was the problem they were looking for when they replaced the first left glow plug? Should I be concerned with this?

Thanks for the help.

It wouldnt concern me, it may have only been 1 or 2 at a time

Yeah, I just realized that. Thanks.
