Re: Valve Lash Adjustment
Dave - Thanks for your detailed response. I don't know a lot about the motor, other than the year of the block and any other info that I've deciphered from casting numbers, which isn't much. I was told that the motor had been rebuilt about 2 years ago, and I've had it a little over a year. I have changed the oil a couple of times, and the first time noticed a few metal flecks in the pan, but not in the filter. Second time, a few less metal flecks in the pan, and none in the filter. According to the maintenance records, not a lot of mileage had been placed on the motor from the previous rebuild, so wasn't sure if I actually this was normal break in or if something was eating itself.
I had a friend tell me the exact same thing with respect to hydraulic lifters, in that they shouldn't need adjustment, and if they do, then it can indicate another issue. The passenger side of the car under the valve cover is very quiet, like a small sewing machine. As I mentioned, the other side was a little louder (like marbles), close to the PCV, and from videos I've watched, assumed that perhaps the lifters needed a little adjustment.
I'm planning on my first engine build at the first of the year, but wanted to be sure that I get as much as I can out of this motor, and thought that adjustment may be in order to assist with its longevity.
I don't have a dial indicator, but might be time to invest in one.
