lifters?
My '02 Tahoe only has 53,000 miles. For the past year the lifters make noise when started in the AM, gradually goes away after 1-3 minutes. A mechanic friend suggested switching to Valvoline in place of Pennzoil, didn't help.
Question #1: Is this a problem? (I'm guessing not)
Question #2: Any easy fix that I should try?
