I can hear the knock when parked and revving the engine by hand. My heatshield used to make some noise but I took care of that. I am pretty sure it is coming from the engine. That said the heatshield was making a terrible noise before I secured it. Has anyone done a valve job on the VX? I thought we had hydraulic lifters but read somewhere otherwise.
On a better not I am reupholstering my front seats with european leather .
Did you guys know the back seats are vinyl?

I really appreciate all inputs.
