Hey everyone, I have an interesting first post.
I recently bought another vehicle to replace my wife's 2008 Nissan Pathfinder. We ended up selling the Pathfinder to a family friend. Before that friend bought it, he took it to the Nissan dealer to have them look it over. It was throwing codes for the camshaft position sensors and I reduced the price accordingly so that he could have them replaced.
Fast forward two weeks and he takes the Pathfinder to the dealer to have the sensors replaced. By the end of the day, they are telling him that it has a crack in the cylinder wall, a crack in the head and low compression in that cylinder.
The buyer isn't mad at me but he keeps asking if I knew that there were issues with it.
My wife has been driving this Pathfinder for four years and we haven't had a problem with it other than replacing a wheel bearing. The engine ran smooth, didn't make any noise, didn't burn any oil, and never lost coolant. It had 115,000 miles on it when we sold it.
I have a fairly extensive knowledge of engines, and also spoke with an independent mechanic about the issues. Both of us agree that there is no way the vehicle was driven to the dealership with the mechanical troubles they are telling the new owner it has.
I believe, during the course of the sensor replacement and when the intake manifold was removed, the tech working on it inadvertently knocked something into the head. Once the engine was buttoned up, they tried to start it and heard all sorts of racket prompting them to do their compression test and bore scope inspection. After all, why are they checking compression on an engine that came in for a sensor replacement?
I'm hauling the Pathfinder to another mechanic on Thursday for them to inspect it as well as get away from the ridiculously high prices that the dealer charges.
So, in everyone's opinion, would we have been able to drive the Pathfinder for any length of time with a cracked cylinder wall, cracked head, and low compression in a cylinder without noticing it?
Thanks
