Q: Engine not running correctly after rebuild

asked by on February 04, 2016

I recently had my engine rebuilt, but the mechanic who did the work, did a rush job. I believe my issue stems from bad valve seals or possibly piston rings. I feel like I should get a compression test done first to help determine the true nature of my problem.
