RE: quattro-digest V4 #803

1st off what kind of car is this.  2nd I very seriously doubt that the 
synthetic ruined your lifters.  Did you change your oil at 3k miles?  If you 
did not this explains it.  Audis are very sucsessable to lifter noise after 3k 
miles.  Mine start clacking at exactly 3300 miles with dino and 3800 with 
synth.  This is with new lifters.  Also if your car has the famed vacuum pump 
it is probably that and not the lifters.

No hard evidence.  However, it gradually started to happen about 4 =
months after the switch (slight ticking sound increasing to a loud click =
in the end) and nothing else changed.  The oil level was always kept to =
the proper level. Also, an automotive engineer friend of mine suggested =
that the synthetic oil caused a difference in pressure in the hydraulic =
lifters that wrecked them.  In fact, I used Mobil 1 very successfully in =
a 1986 Chev Blazer for years...I've got nothing against synthetic oil.

Whoa, hold on here! How did using Mobil 1 (a generally LOVED and =
engine oil) cause your lifters to go bad? I've heard that a broken-in
engine will leak synth oil when first introduced, but did your oil get =
low as to cause this type of damage?
