Reading your other post, regarding valve clearance, You stated that you're using Comp 911-16's, These go in at 1.900/ 122lbs to 1.850/141 lbs. I'm gona ask NO click/tick when engine is cold? I watched the video. Low oil pressure when engine is warm? 10-12 or 13 lbs at idle aint gona cut it at keeping a hydraulic lifter filled with that kinda seat pressure. Especially with a 1 size fits all lifter program from Comp. SBM and BBM lifters kinda aren't the same.
