We have a problem with low oil pressure. This problem started after a valve adjustment. So did a valve adjustment created this problem or something else.
I have sent the oil for analysis will get the result shortly.
That's an Acert, which has 3 small oil transfer bridges going from the head to each actuator housing. I'd pop off a valve cover and check them out. If they pulled the actuator housing off to to the VA, they may have put them back on wrong, cracked one or forgot to put them back on. I've seem them cracked if the o-ring is not in the groove and they're tightened down.
Any noises or engine codes? If it's oil going to the top-end, you usually get a intake actuator pressure fault.
