I have a 92 maxima with the VE30DE engine. I got it cheap b/c it was making a top engine noise. Previous owner said it was the timing chain. I did some online research and decided to start with cleaning out the tensioners which went smoothly but the sound remains. I removed the valve cover again and found the vtc assembly at the end of the intake camshaft way out of line pulling the top timing chain toward the from of the engine. So much so that the VTC assembly has made wear marks on the valve cover and the front cover. I also notice that this VTC assembly is missing a cap that is on the other VTC assembly. At this point I'm hoping that if I can install the missing cap my problems will be solve.
Any input would be soooo appreciated. And even more so if anyone has a old vtc assembly that would be willing to part with this cap I would be super stoked. (I know it's a long shot right )
Many Thanks
