1991LS400 Posted November 28, 2004 Share Posted November 28, 2004 Hey guys, I believe I saw a post on this somewhere before but I'm going to ask this anyway because I like it when I'm replied to rather than read someone else's post. This only happens when I first turn on my engine and I'll hear a knock like a "thunk" when the engine turns on. What could that be? Please help. Thanks everyone.

1991LS400 Posted November 28, 2004 Author Share Posted November 28, 2004 No, I'm sure it's not "normal." Anyone else have any other ideas? :whistles: Quote Link to comment Share on other sites More sharing options...
VBdenny Posted November 28, 2004 Share Posted November 28, 2004 You sure it isn't a clunk from the starter disengaging? These old starters tend to hang engaged sometimes and give a clunk like that. Quote Link to comment Share on other sites More sharing options...
