We took our well loved 2004 VW Jetta wagon to Zahntech for diagnostics regarding engine noise. John seemed very knowledgeable and courteous. It was determined the noise was coming from the crankcase and we decided to have them replace the block with a good used one they had at their shop. It was close to $5000 when all was said and done. The vehicle broke down on the highway after leaving the shop. It was a crank sensor and was fixed. The first long trip after picking it up, the check engine light came on and my wife took it to the VW dealer in San Luis Obispo. The check engine light was on due to a faulty sensor but vehicle was also 3.5 quarts low on oil. She had to keep adding a quart every 600-800 miles after that. We called John Zahn and explained the situation, he asked us to have it looked at again so we took it to the local VW dealer. They performed an oil consumption test where they weighed the oil they added and we drove 600 miles and they drained and weighed it again and determined it would consume approx. 1.5 quarts every 1000 miles John Zahn asked us to bring the vehicle back to him. My wife drove up and left the vehicle with them for over a week. They called her and said they fixed it. She went back and picked it up and drove south to Oregon where I met her. She was complaining that it drove poorly and wasn't the same vehicle. I drove it and thought it was sluggish. I called Zahntech but John was unavailable. I was told he would return my call. On the way home I followed her and noticed the car would smoke on any incline. I took video of the smoke clouds. When we got home I parked the vehicle at my shop on a new poured concrete slab. When I came the next day there was a giant puddle of oil underneath the car. I was very upset. I called John Zahn again and got him on the phone. He was very defensive and rude to me. Accusing me of making up stories of how the car was broken and that I didn't want it to be fixed. He said and I quote "there was nothing wrong with the engine you had in your car! I know because I put that engine in my son's car and he drives it every day". I said what engine did you put in our car? He said "I put my son's engine in your car, it's a good used engine". I took the car to an independent VW repair shop. They looked over the engine thoroughly. They were appalled by the condition of the motor. I have an extensive list of issues I sent to John Zahn. Who told me there's nothing he's going to do to help us. Honestly, I've never been treated like this by anyone. John Zahn was very immature and unprofessional and rude and accusatory as soon as there was a legitimate problem with the work performed by his shop. On top of everything he totally disrespected us by removing our drivetrain and replacing with his son's??? He never called to explain he was going to do that??? Who does that? Nobody does... I called and demanded to have all our original parts back. And he said "that will be impossible because I sold that car I put your engine in." Seriously.
We installed a used engine in your car 3 years ago. Sometime after that you told us it was consuming a significant amount of oil. 13 months later we replaced the engine under warranty with another used engine with lower mileage than the engine that we originally installed. We also installed a new camshaft and updated lifters as well as a timing belt and water pump with all related components. The engine was from a car I personally owned. I did this because I wanted an engine that I knew for absolute certain was in excellent condition with no oil consumption or any other issues. This was way more work for me because I had to remove and install two engines instead of one. However, because the car was returning to California and we were dealing with used parts I wanted to be extra certain there would be no problems. We did all this at no cost. When the engine left the shop, it was in excellent condition and had 450 PSI of compression in all 4 cylinders. I know this for certain because I installed it myself. Having been two years since we have seen the car, I no longer have the information required to address the apparent communication issues. However, it is clear you aren't happy, so we failed and I'm sorry. Sincerely, Matthew
