GLS 6CYLINDER WITH WHAT SOUNDS LIKE A VALVE TAP

2002 Hyundai Sonata • 100,000 miles

The car sat for awhile I changed the oil added some lucas and it went away for about 3 months and now its back and I only put maybe like 400 miles on it in those 3 months

Is it constant? Only on cold start? Does it change in noise level with different rpm/temperature?

Ya it stays there even after car has warmed up and it gets faster with rpm's

You might try a heavier grade oil? Or pull valve cover and inspect for visible defects.

Has hydr lifters directly under cam lobes on top of valve. A single tap could be something else or just 1 bad lifter.

It is advisable to replace all lash adjusters as you do not want to repeat the job again if a second one fails in the near future, remember that they all have done the same amount of work, so another failure may not be far away.
