the lifters were definitely opening the valves as to why no compression. i went to advance and purchased one. i noticed right away i could compress this on holding in one hand and pushing down with finger. i filled it with oil and was still able to compress at a slower rate, oil was pushed out the bottom as i thought it should. went back to advance and purchased complete set and installed and as of now the engine is running. although it still has the original ticking as before it was worked on. now i will try to get reimbursement from dealership, by the way i purchased one extra lifter and will not open it until in the presence of service manager. thanks for your help
