Lifter tick???

**A RAIR 99** · 10-13-2008, 05:53 PM

Hey, guys-I just did cam/LT's/ORY/LS6/pr,spr,ret/oil pump on my '99 SS, but now I get a ticking sound from the car that sounds like a lifter, but not sure why it comes and goes every now & then? When it develops, it gets progressively louder- especially when I'm on the gas, but the ticking slows when I push the clutch in. 1 time 2 weeks ago the tick turned into a knock right when I got home to put in garage, but why would it come & go & not stay constant? So, is it a bad lifter or what else could it be? Thanx for the help

is it more prominent when the engine is cold? if its constant or doesnt vary with temperature have your oil analyzed its possibly a faulty rocker arm, when you put your new springs on when doing the cam its possible you may have upset one of the roller bearing trunions causing one of the rockers to make a small ticking noise, good luck

If it's adjustable lifters, you might have lashed them wrong. I had that on my engine swap, it will sometimes take a couple times to lash them.

Yes-usually only happens w/in 10 minutes of start-up & I didn't put the car back together, so I dunno what they did, but a friend of mine & a guy who had a 7 second dragster that I met a couple times b4 did it, so I'm pretty confident in their work. However, they did forget to put in the new oil seal & front cover gasket that I gave them & used the old ones!!! Thanx for the help & keep it comin' anyone else

Mine was ticking after i put the cam in, and I ended up going with a longer pushrod... did you check the base circle, and compared it to the base circle of the stock cam?
