Problem Reported: Valve lifter noise
December 03, 2010, 09:13 AM
<p>A hydraulic lifter type noise may be noted, often worse at idle. This can be caused by air being drawn past the <a id="ce_90" class="ct_selected tooltip" href="/oil-pump">oil pump</a> seal allowing aerated oil to reach the valve lifters. Replacing the oil pump seals generally will correct this issue.</p>
