As I was driving at a speed of 45mph the low oil pressure sensor light turned on and then turned off. The next day I thought it was gone but then it turned back on and this time the sensor light did not turn off. After this light was still on I decided to take it to jo tech (972) 494-2100. When I took it to jo tech I was told that this was not just some small sensor issue but an engine problem. After finding this out I towed it over to courtesy Nissan. At Nissan I was told the engine warranty was not valid and I would have to be paying out of pocket. I asked for a quote from them and they were giving me a price of $56,000 to repair. This quote was obviously way too high. I made the decision to get it out of there and over to t1 race development (214) 607-9022. As they opened the engine they discovered the following, " well this is definitely an odd one. It looks like a stock tensioner/guide failed and allowed the chain to dig into the front timing cover which through a ton of metal into the oiling system". I was trying to attach images/evidence that t1 sent over to me to show this engine problem was because of a manufacturers defect but file was bigger than 5mb. Feel free to contact both shops for the full report and to get the rest of the images. Feel free to contact me directly as well. (469) 432-1623.
