Hello all. I had a shop perform a compression test after they completed the water pump swap. Here are the results: 130 125 115 120 This was with a cold engine. Plus, the altitude at the shop is about 5350'. Mileage = 130,000 They suggested valves. Any opinions? Thanks! Eric A. Cobb 91 Black Classic Driven to 130k SE-R.Net Multimedia and Parts Editor
