Another one of those guess that noise thread. Bill/Scotty ready..set...go....
04 87k, vs cam, 90lb, stock timing chain, heads were cleaned and decked. SD headers, lq4, ls7 lifters etc AL 104 gapped at .50. Stock pushrods
Decided to go ahead and get the car on the road again. I had a massive exhaust leak as well as what I thought was a bad lifter tick. I tried the seafoam trick.. Still was there. Tried some Lucas in the oil.. Still had this ticking. Decided to go ahead and pull the SDs and modify them since I needed to replace the crappy Felpro gaskets. I also went ahead and changed the lifters thinking one may of collapsed. Pulled the lifters and they all appeared fine but I went ahead and changed them. Finished the SDs and installed them back (no more exhaust leak) but ticking noise is still apparent and I'm having a hard time pinpointing where it is. Rockers were torqued and none of them appear loose.
First video was before I fixed the leak and with my old stock lifters. (Ignore the belt squeak)
Today's video
Already checked the basics
-no cel
-plugs changed and old plugs were fine
-oil changed and no glitter
-doesn't seem bottom end related seems to quite down when I idle it around 2k or so. Will have to double check once I have a buddy that's free
-I tried the old screwdriver trick and still can't seem to pinpoint it but it does sound more apparent from the front of the motor then the rear.
I'm open to suggestion. I don't remember how much the heads were decked but it was just enough to clean them up. I haven't ruled out maybe the pushrods are to long just yet but rather double check here and get some suggestion before I order the tool.
