Man have I got a story for you guys. For the past few months my 02 Altima 2.5S has been running like ass and since the last oil change I have had to add oil 3 times so I figured since it just rolled over 100,000 miles I needed new plugs so I got new plugs and some fuel injector cleaner. Well, nothing I did seemed to help, in fact it was getting worse. Well last week I went to pass another car and when it hit the passing gear it made a noise that sounded almost like a blow off valve. Over the next few days it got to the point that it did it all the time and I realized that there was a clogg in the exaust system and the back presure blew out the doughnut gasket. I took it to a repair shop and the guy said that the catalytic converter was clogged up so we called the Nissan store in Pensacola FL, and they gave me a price of $377 for a new converter. I went ahead and drove it home and decided to do the work myself. After I took off the heat shields and I realized that the converter was made into the exaust header and because of where it was it did'nt make since. The clogg had to be behind the doughnut gasket because thats where it was blowing out. I went ahead and took off the converter and to my amazement it was hollow, totally empty, the only thing in there was a large metal ring and of course 2 O2 sensors. Well, I then realized that the clogg was behind the converter. Well behind the converter is a cylinder that looks like two ice cream cones stuck together and then what I assume is the resonator and then the muffler and I did'nt know where the guts of the converter went. I use to work at a Nissan store and I had gotten the sales manager to go ahead and get me the converter with his discount and for those who care his price was $175 plus tax. so I called him and told him I did'nt need the converter, I figured for now I would just run mine hollow. I called the parts manager to see where he thought the clogg was and he decided to check the vin for recalls which I had already done at Nissan's webb site and all I came up with was the crank position sensor recall but when he came back on the phone after checking he said that there was a complete exaust system recall. NOW AIN'T THAT SOME SHIT! Im a little upset with Nissan because noone bothered to contact me to tell me that I was destroying my engine slowley. It has'nt been that long since I took it in for the crank position sensor recall and they did'nt say anything about it in fact when I got it back the "check engine" light was still on so I took it back and they said that 2 O2 sensors were out. Now that should have rang some bells. Before the warranty ran out I took it in for an oil change and I told them that it was starting to be a little sluggish and that the fuel milage went from 32 to 22 mpg and they told me that there was nothing wrong with the car and that my driving habits would determine my fuel milage, now I admit at times I am an aggressive driver but this was not the problem. I talked to another guy that was selling the engine out of his 03 2.5SE that was recalled because of an above average oil consumption rate that lead to pre-mature catalytic converter failier. Kinda sounds familiar dont it. I dont know if they are going to replace the engine or not but they need too. There is no telling how much perminate damage has been done.
