Hey just to let you know what is going on with my attempts to view that zcar. The owner sent me an email last weekend and said he had the compression checked and it was 100 psi on all cylinders. So he has put the z in the shop with to get it checked out. He was told by a mechanic at the nissan dealership that it could be that the valves need adjusting. I emailed the owner back and said that I thought it was probably time for an engine rebuild due to the compression being down on all cylinders. I also asked if the mechanic/dealership would guarantee their fix to remedy the low compression. He said he would be in touch when he had further information. I like this z but now I am scared to even think about what else is going on with this vehicle.I will give the owner hats off for being upfront about the issue.
