Mazda service are the experts, not me. Worst case scenario, they should have informed me that oil sludge caused the turbo to fail. Even though the Mazda CX-7 has a known oil sludge problem and an "F"ed up PCV valve configuration (to the Mazda service shops…not Mazda owners) on the 4 cyl turbo (hence they stopped making the CX-7), I paid $3,000 for not changing the oil more regularly. My bad, but I paid the price. Mazda should have diagnosed the problem, cleaned out the sludge and informed me to follow a specific regiment of maintenance tips, ie more regular oil changes. I was already using synthetic oil. Most of the mileage was interstate and my wife drove it 150 miles to and from work daily or about 850-1000 miles weekly. Am I supposed to change the oil every month or 12 times a year? Stop blaming the owner and tell me what should have been done by the Mazda dealer. I don’t tell my doctor what needs to be done…he…she…tells me what I need to do. They are the expert. After the rebutle I just gave, don’t tell me what I did wrong, because my problems should have ended after I forked out $3,000 to replace my defective turbo. Mazda didn’t tell me my arteries were clogged and to start eating more healthy and to get more exercise, they just put a stint in my artery and sent me home. The doctor diagnoses the problem, repairs the problem and provides a preventative maintenance program and so should a professional mechanic. Now I have a car with no engine or turbocharger. Now…blame me. See below… “Definitive Guide for Your Mazda CX-7 Turbocharger”. > **[The Definitive Guide for your Mazda CX7 Turbocharger - Mazda CX3 Forum](http://www.cx3forum.com/forum/cx3forum-com-forum-information-help/2225-definitive-guide-your-mazda-cx7-turbocharger.html#/forumsite/21270/topics/2225?page=1)** > > Mazda CX3 Forum The above procedure outlines the specific steps when replacing a defective turbocharger in a Mazda CX-7. Bob Moore Mazda Service in Oklahoma City, did not… 1. Diagnose the problem and repair it. 2. Change the oil 3. Change the oil filter 4. Change the air filter. The procedures outlined above are specific, detailed and clearly defined. Do mechanics not have a procedure manual like this one to guide them through most every repair or are mehanics born with an inate ability to fix anything by flying by the seat of their pants? I’m Sick and Tired of mechanics hiding behing the “it’s your fault” methodology of why your car blew up…it’s not mine! I’d love to hear your thoughts on replacing a blown turbo with shards of metal and plastic pieces floating in the old contaminated oil, when all they had to do is follow the procedures outlined in the link provided. Since they charged me $3,000 and handed me an invoice 3 pages long, do you think I would have told them not to change the oil that would added $40-$65 additional cost to my invoice, especially since that’s what caused the failure in the first place and I needed a damn oil change anyway? I even told them to change the oil and they didn’t. OMG! They should make everyone change the old crap oil, because if the turbo fails within the warranty period for the replacement turbo, they are on the hook for another turbo repar at their cost. They changed the fricking spark plugs…and not the oil. They had the car for 7 days. Mechanics are drivig me CRAZY! --- _[View the full topic](https://community.cartalk.com/t/turbocharger-replacement/97648)._
