I took my car to Doral AutoTech this weekend to do my major tune up & I had ask him to see if they could adjust them & the owner of the place told me they are hydrolic self adjusting valves, that there is very little adjustment to be made. So does anyone really know what the problem or fix is. I've read the other threads but most of them are old to let's see if anything has changed. Thanks....
