f6 man New Member 3 Member For: 8y 3m 13d Posted 08/10/16 08:17 AM Share Posted 08/10/16 08:17 AM Hi guys ive recently purchased a 2011 fg f6 with 85000 kms it had a slight miss when I brought it. I'm trying to determine why one cylinder has only 120psi compression. Ive had a camera inside the engine the pistons appear to be fine. Ive also had a lot of oil in my cooler pipes and delete pipe does anyone have any ideas what this might be. Does anyone know what tests are usually done to determine if the rings are stuffed or the valves. Thanks. Link to comment Share on other sites More sharing options...
