Hello everyone, I recently completed a rebuild of the engine in my Healey
3000. At 48K miles i noticed metal during an oil change. I dropped my oil
pan and found even more metal and a silver ring in the block that lined up
with a cam lobe. I had been using Mobil 1 for years and always had good oil
pressure and a very quiet motor. I pulled the motor and upon teardown I
found one bad cam lobe and several lifters that had mild pitting. I
thought about how I used my car and came to conclusion I, rather than the
oil might be the reason for the cam failure. I drove my car every couple
of weeks in nice weather. This is just enough time for the oil to leave the
cam and lifters to drain into the pan. This meant the next time I started
the engine the cam and lifters might have been metal on metal. My new
lifters are short bucket lifters with a drain hole to lubricate the cam
lobes. Now using VR-1 20/50
