I just had the lifters changed on my 2013 Yukon XL. The camshaft was not changed as the mechanic said it was in good condition. However, the oil manifold was replaced and one of the valves was damaged and had to be machined. The total cost for parts and labor was over 4100 dollars. Wondering if someone can look at this invoice and see if it seems reasonable.

They got you on parts. Looks like they charged you for 15 to 20 hours labor depending on rate which the invoice does not show.

Yeah, those parts prices are steep, but I don't know your region'* market so maybe those prices are competitive. Costs today are going up and skills are going down. If you got it repaired by a shop that could actually diagnose this caliber of problem, take it apart, fix it, put it back together correctly, then warrantee it for 12mo/12k miles, then you're doing pretty good in many areas. Real diagnostics is becoming a lost art.

If you have a bunch more money in it doing diagnostics prior to this invoice, then maybe that'* another story.

This isn't just about comparing your invoice'* part prices with retail prices. The shop also has to factor in all of the costs of keeping the place running, cushion in case the car comes back on warranty, and still compete against the other shops that undercut them on labor prices while likely not having good diagnosticians on staff like the one that you got.

Personally, I wouldn't fret about it if it lasts through the warranty period.

. . .and separately: the time to question prices has passed anyways.

I spoke with him candidly. It'* a good shop and the company I work for takes all of our vehicles there. He settled the bill for $3500.00, so I think I am satisfied with that.

Wow, that'* great! I don't often hear of that these days!

There you go.
