On 3/3/2021, it was confirmed that an internal engine valve was broken and Dat recommended an engine valve job/service to replace the broken valve. Because the engine valves were covered with my maxcare warranty plan, I was not expecting additional costs. The labor and hours are consistent with what it would take to replace the engine valves, however Dat claims another 10-15 hours, which will be my out-of-pocket costs, and I agreed to the extra costs. To be more exact, it took 4 weeks to finish. There were multiple phone calls and texts made to provide updates to my car, as I heavily depended on my car to commute to work. On 4/1, the car still wasn't ready and that was when Dat transferred the car over to his other shop to finish it. On 4/2, Dat confirms that the car was ready for pick up. On 6/21, I took my car to another shop and they denied me service because of the previous poor quality workmanship; I had missing pieces/poor quality installation, and my engine is upright. The current shop mechanic that was inspecting my car had noted varying differences in how the engine was bolted back together; he continues on to show me the previous service that was done; the engine had bolts that were either too long or too short. The long bolts stuck out halfway which means that at a certain point, it either hit something internal, i.e. my intercooler bolt was too long and did not get a flush bolt installation, meaning that it could have the potential to have been drilled into the intercooler itself and can cause damage to the intercooler. The short bolt on the other side of my intercooler looked to be too short and was stripped in the process as the current shop mechanic wanted to verify if the correct bolts were used. After failing to pull it out, he noted that the threads must've been stripped and is unable to pull back out. On a component that extends from the intercooler and connects elsewhere, the current shop mechanic noted that the bolts were brand new and was questionable about what could've happened to the original bolts. The concern here is that the new bolts did not indicate whether or not it was spec'd out to be used as engine bolts and can be seen as defective as time goes on. Because of this instance, there is a potential damage to this component if it fails because the bolts may not have to proper material spec and torque to hold it down. Nearby the timing belt, there is a bolt that was used that just didn't seem to be like it belonged there. The bolt head itself somewhat resembled a wavy round design. Again, this bolt is questionable to be used as I don't know what the specs and torque requirement for this is, and if at a future date this bolt fails, it was because the precision and quality was not there to replace these bolts based on spec requirements.
It was also brought to my attention that there are several missing bolts from the undercarriage of my engine. As it was lifted for us to be able to check the missing bolts, the current shop mechanic noted that there were missing bolts that held my transmission together. If that being the case, I was at risk for driving without any knowledge that the quality installation was not present at the time of dismantling my engine and re-building it and dropping it back into the engine bay. Knowing that I was missing a bolt on my transmission was a risk to me, clueless that I was potentially driving on a loose transmission for 2 months after the car was returned to me. The current shop mechanic then went on to point my driving/steering axles and that it was leaking fluid. If and when they took the engine out, there needed to be a precise and slow lowering of the engine so as not to damage other components. I wasn't sure on how to stop the fluids from leaking and this was a potential damage when my car was being worked on. As we lowered the car back down, he made a quick note on the whereabouts of my intake valve cover and that it was missing. I hadn't noticed that my valve cover was missing but I was sure that when I replaced the air filter, I had to remove my valve cover. Seeing that it was missing shows the quality of work that was being performed as they put everything back together. The current shop mechanic also point me back to the intercooler where the cover was loose. Both sides typically are held down with some sort of angle closure, bracket, etc. But in this instance, my cover was outright loose, meaning that I've been driving with a loose cover all this time and had the potential have gotten caught in something, dropped throughout the engine bay, and can be validated as a potential damage to my car and my well being. The most noticeable feature that lacked the quality of work was the service of my belts. The current shop mechanic went on to point out the dangers of this as he noted that the belt was eating into the belt cover and exposed a metal component. read more
