Re: my recent solution to noisy valve lifters??

[Brett N Augsburger <augsbbn@eng.auburn.edu>]

 I used the same engine cleaner to successfully rid my own car of noisy 
lifters. Just make sure you don't drive the car with the stuff still in 
there at all(not even to the oil change place)! It has been 20,000 miles 
and a year and a half since and I have not heard a thing from the lifters. I 
believe synthetic oil also helps because it eliminates deposits formed 
from the high heat and breakdown of conventional oil.
