I so appreciate everyone who is trying to help me with a very challenging situation. I need assistace here, but if you're not going to read what I wrote below...don't bother. Skimming the below info and thinking you know what I'm going to say, isn't going to work.
It's clear from some of the responses, my info isn't being read. Some people are so ready to read me the riot act, they don't take the time to read and understand the situation I find myself in.
I understand what you are saying, but pease stop telling me what I should have done and didn't do and enlighten me regarding what Mazda Service DIDN'T do and what they SHOULD have done.
He we go...again!
Once I received my car back from Bob Moore Mazda, what I did in the past is over and done. I now need to know what shape my vehicle is in after service and what needs to be done, if anything, from preventing this from happening again.
FYI...Regarding what "I" should have known and what "I" should have done...
I'm not a motor guy, but I wish I was. You guys are so much smarter than us drivers.
I was very young when my family raced competitively. I've been testing with NASCAR teams for many years. Not because I'm such a great driver, but my family's ties to racing. Buck Baker and Marvin Panch were close family friends and my Mother's driving coaches. My Father was business partners with Tiny Lund. All three men are in the NASCAR Hall of Fame and won the Daytona 500. It doesn't hurt that my brother in law is a famous country music personality. It's not what you know...right?
When I get to the track, my seat and setup are ready to go. All I do is shake the car down, in an effort to get the primary dialed in and occasionally, tire testing .
This is where the rubber meets the road and I need your help. Please understand what I'm about to ask and give me an honest, but reasonable answer.
Yes, I was partialy responsible for sludge buildup in the engine. I got that! Hence the $3k it cost me to have fixed. The turbocharger was not under warranty.
The 4 cyl. Mazda CX-7 has a design flaw in the PCV valve that causes terrible engine sludge buildup. I only found this out when my car died and I googled the problem. That's why Mazda doesn't make the CX-7 any longer. (CX-3, CX-5 and CX-9) Like clockwork, most CX-7 4 cyl. turbo owners lost a turbo at 75k miles, primarily due to premature sludge buildup in the engine.
...so everyone please stop crusifying me for this disaster for one minute and assume what I'm telling you is correct, so I can begin to better understand who should have done what.
Now...Bob Moore Mazda has my wife's CX-7 in Oklahoma City and she returns to Arkansas (6 hours away). The car died while she was spending the weekend with family in Oklahoma. The turbo had a high pitch noise and the CX-7 lost significant power. She had it towed to the local Mazda dealer. Bob Moore Mazda kept our car for an entire week.
This is what I believe should have happened and hopfully every reasonable, non-mechanic would have as well.
Here we go...In my opinion, Mazda should have...
A. Diagnose the problem. (Damaged turbocharger)
B. Diagnosed the reason the turbocharger failed.
C. Fix the underlying cause of the problem.
- Remove the sludge from the engine.
- Make sure the PCV valve was clean and functioning properly.
D. Repair and replace all of the components that have anything to do with the defective turbo/oil eco system of the vehicle.
"CHANGING A TURBOCHARGER"
Section Two: Oil Pipes and Engine Oil
Before you install the replacement turbocharger, the first job is to change the oil and associated filtration systems. Remove and replace the oil feed pipe from the turbocharger and ensure that the new pipe is free from kinks and blockages. Then replace the oil filter and replace the engine oil. It is important to have new, clean oil as impurities in older oil could play havoc with your new turbocharger’s bearings. Finally remove all the crankcase hoses and filters, and either clean or replace them in line with the recommendations in your owner’s manual._**
IS THE ABOVE SO DAMN HARD TO UNDERSTAND??? OMG!
E. Explain to the car owner why the turbocharger failed, what had to be done to remove the sludge from the engine and tell them exactly how often to change the oil,oil filter,air filter and fuel filter. Specify the type of oil, synthetic is recommended for turbocharged engines.
F. Charge $3,000 for everthing and thank the customer for choosing their shop, because they could have gone anywhere.
THAT IS THE WAY THIS DEBOCLE COULD HAVE BEED AVOIDED AND HOW A PROFESSIONAL AUTO SERVICE REPAIR FACILITY SHOULD BE RUN.
Stop thinking like a mechanic for just a moment and put your customer hat on...a customer that knows nothing about a car, except fill it with gas, change the oil and check the air in the tires. Hypothetically speaking...
Why did I get my car back from the Mazda service shop without my oil, oil filter, air filter and fuel filter being chaged?
Why didn't the Mazda service shop diagnose why the turbocharger failed?
If the Mazda shop had diagnosed the problem...why didn't they attempt to remove as much of the engine sludge as much as possible from the engine...if not all of it?
Why didn't the Mazda service shop tell my wife what they found and how we could possibly prevent it from happening again?
