Engine Ticking 900

posted by  someone claiming to be 93-940 & 99-V70 on  Fri Apr 2 13:38 CST 2004 [RELATED]

The B230f engine has what are called valve noise dampeners (I am not sure if this is the same as a B234 engine, if it is, then the following applies). They are essentially "Y" shaped rubber "bushings" that quiet the tapping sound of the valves. Sometimes the mechanics will actually remove them when doing a valve adjustment, and not replace them, as they do no other function than quiet the valve tapping. The engine is not harmed without them. As they get older, they start to resemble a "T", and thus to not stay in place and move up and down the shaft. At that point they work sometimes better than others. When you get the valves adjusted again, have these checked.
