I can count the number of Hyundai oil pump failures I've ever seen on one
hand. According to the service manual, the pressure should be about 21PSI
at idle. The dealer isn't likely to ask for service records unless it
actually appears that the oil wasn't changed at the proper intervals.
If you have the 1.5L engine, the most frequent cause of lifter tap is
sludge clogging the oil feed holes in the rocker arms. Usually, removing
the rocker arms and cleaning out the oil feed holes cures the issue. Of
course, sludging isn't a warranty issue.
If you have the 1.6L engine, check to be sure the flap inside the oil fill
hole isn't pushed down into one of the rocker arms. If it is, it'll sound
remarkably like a lifter. In that event, simply take a hook and pull it
back up.
