Good afternoon. I was just told that my 2013 Yukon Denali 6.2 has a bad lifter. The mechanic recommended replacing all 16 lifters and told me it would be around $4,000.00 to complete the job. Does this sound reasonable? I don't know much about this sort of thing but have read that the lifters are a problem.
Thanks
Yes, I've seen quotes for that much and higher, up to around $5000 or so. I've done this job on that engine 3x so I know it first-hand. I can do it now in about 16 hours, including the cam.
That said, the book time for the job according to Alldata is 12.6 hours to R&R the lifters for both banks, and it goes up from there if the cam has to come out. Add another 4-6 for the cam, etc. if necessary because the radiator has to come out, front cover and timing set, harmonic balancer, power steering pulley, etc etc. So, book time for just the lifters at $150/hr will run about $2K, add another $600-$1K if the cam comes out, plus parts, which will be $1-1.5K for OEM parts, gaskets and fluids. Summary: $4000 is a fair estimate that will leave some wiggle room. If the cam doesn't need to come out then it will save you probably $600 off that estimate.
You can also do this job yourself if you're handy. I have a writeup here on it that you can use as a starting point.
