Service shop identified engine performance problem, replace all fule injectors, test drove, still had problem, then checked on internet for others with same problem, identified #1 cylinder needed to be fixed. Gave me quote, then in the process of removing engine bolts, service shop broke 11 of the 14 engine bolts, now quoted me new price to tap and remove all these engine bolts. Questions, should this be part of the original quote, or is the "oh crap" lets charge the customer for additional hours it is going to take us to fix this problem. Thanks in advance for your help in this matter.

Yes, service salesmanger showed me the 11 broken head bolts. I agree, perhaps the service tech is not very good. If you happened to break a head bolt, who would pay to remove it. 11 of the 14 bolts broken off sounds like the tech does not know how to do it. I do not want to pay for stupid time. Salesmanager told me it would cost thousands to remove head bolts and then the tapped bolt locations may not be as stong as they need to be. What a mess.

After some checking found TSB on broken head bolts for that engine. They are torque to yield and tend to break on removal. Proceedure is to tap bolt head with punch and hammer then remove. But still could break so if this is not a GM dealer and TECH not trained then that is why such a high number broke.There is an extractor tool to remove bolts you can get from GM part # EN-47702. TSB is 05-06-01-026B OCT> 21, 2008.
Hope this helps

Back to original question, what is the industry standard, WHO PAYS the labor to remove broken bolts, customer or service shop. Thanks in advance for your help in this matter.
