Oil pressure question.

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.

Yes.. cold I got aprox 40 PSI at idle, I'm pleased with how smooth engine runs, as it warms up to operating temperature I'm at aprox 13 PSI warm at idle, I get the tick/ clack from I'm assuming lifters, I did readjust the preload lastnight on drivers side bank to 1/2 turn. Didn't seam to make much difference.
