Ok guys, got one for ya. I did a search on lifter noise and only could find threads that say "upon startup". I too have that noise, but also right before it shifts from 1st to 2nd and sometimes from 2nd to 3rd. I looked at the oil life monitor when I first noticed it, and it said 46%. Now I change my oil at 3000 miles anyway and do not go by the monitor. Just changed oil today and still doing it. Is there anyway a timing sensor could be intermittent ar something else? Thanks in advance for all the help.
