One Cylinder On The Low Side

  1. Well since rebuilding my 2v about 1500 miles ago the car just hasn't been that impressive, even with 410s in the rear so I decided to run a compression test and the results were, 7 cylinders all had between 180 and 185 PSI but number 5 only had 150 PSI.

    Would that make that much of a difference in power ?

    I ran the test on that cylinder wet and the compression shot up to around 210 PSI.

    Im guessing the rings did not seat completely,either that or I set the top ring with the bevel downwards.

  3. Oh ok thank you for telling me what to do
