Well... we need more info on the tick you are experiencing.... is it all the time when the motor is fully up to op temp? Or is it only noticeable on a cold startup and you hear it for a few mins then it goes away?
when i start it up about 15 seconds in ill hear a slight tap. 3 out of 5 times.. Before it was a SLAP and everytime. But it will come and go Sometimes it's a perfectly sounding engine and then taps randomly then back to perfect sounding.
An oil filter lacking, or having a defective antidrain back valve can cause lifter noise upon start up as the oil pump must refill the filter, which inturn reduces oil flow to other engine bits, like the lifters. I have had this happen, it was the filter issue. different, i.e. better filter fixed it.
I believe it's a sticky lifter. And the zinc has made a thin barrier making it less noisy. But I still take it to Redline when I merge onto the free way. If don't beat on it just it the Italian tune up.
