I just replaced the starter and did spark plugs on my 98 Ls? I also replaced all the vacuum lines and new radiator and upper and lower hoses. I was wanting to have a base level of engine service going forward. I have had the car for a couple of years before the starter failed. Long story short......
I have noticeable valve clatter/noise now that I do not recall having before doing the work.
Any thoughts?

 

how is your oil level? are you certain the vacuum lines are in their correct positions?

 

Oil is fresh and to the correct level. Vacuum lines were replaced via photos prior to tear down for the starter. I'm still running the same tank of gas that was in it when the starter failed back in January. It was way to rough a winter to get to it any sooner.
