Chime in if you have had issues with your cylinder head on the 3.7L engines only.

We are not interested in the 3.5L issues, we all know them well.

Chime in if you have some experience/input on this subject.

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
