I just got my compression results in for my 2008 3.7L Colorado. I performed the test due to the fact that I am experiencing some of the issues posted on this thread. The compression falls between 172 and 180, a variance of about 4.6 percent well under the 15% that may indicate a valve leak. The variance seems okay but the pressure seems low compared to the 215 I have read to be normal on these engines. Any help would be greatly greatly appreciated! Thanks
