A few things I disagree with:
I dont believe the HLA ticks because the ball valve cant hold pressure. I believe it fails because it cannot get pressure. The HLA gets so dirty inside that It doesnt get the presssure needed inside the midlde part to function properly (usually at idle). On the motor I rebuilt, The HLAS ticked as normal. When I took them out, they were as hard as a rock. I could barely get them apart, couldnt push the plunger in by hand. Id suggest that as a HLA in need of cleaning. I cleaned them, installed them, the motor sounded like brand new and ran like brand new. Now I have that same motor in my garage, untouched, still brand new as ever. with the VCS pulled off it, and I can push in every HLA by hand. And I know I can put it in a car someday, start it up.. and it would be just as quiet as ever
The motor pressurizes the HLA via the oil pump. The HLA's should operate at whatever your oil pressure is at.
YOu dont need to put oil in them. Simply assemble them, hold them under a tub of oil and pump them a few times. Let them soak in it for a few hrs if needed. Upon start up, the motor will fill them.
Also, Diesel fuel is good to clean them in. It eats off all of the grime, while still having a petroleum base to keep from ruining any parts.
I used silver bullets write up on probetalk back in 2003.
