| So look to the CAS and the CAS sensors at the rear of the heads. Based on the compression numbers the valves appear to be ok. To verify follow up the compression test with a squirt of oil in each cylindere and if numbers go up the valves are most likely not the issue but some air loss there would indicate the rings are somewhat worn. The degree of increased compression will provide a measure of the ring wear. According to this link TT perfect compression is 174 (per Ash) and 121 min with 14 psi max difference from high to low.
