If it is that noticeable, I would try to norrow it down to a point in the motor, then yank the intake and take a look at those lifters in that area, look over the cam etc. then button it back up and see.

Oilo additives are a temp fix, but if its a sticky lifty (disk inside lifter not responding etc) then they can "loosen" it.

 

Mine started doing that. Only after it warmed up. Kinda subtle sound. It turned out to be the #8 rod knocking. I had to pull the motor out of it and put a new crank and bearings in.

And YES, it will affect your performance because the knock sensor picks it up and retards the timing. Makes it run like a dog.

 

Car runs great... picksup fine and cruises no problem. So you think I should just try the Slick500? Should I do an oil change asap? Because I just did one less then 2 weeks ago

 

Also, car sounds NOTHING like the audio sample from Shoebox... it sounds like a clock ticking... very subtle and weak but noticable.

 

No one?

 

You said the knock sensor picks it up... but I got the OBD1 conversion, doesn't that conversion turn that sensor off?

 

No OBD1 uses the Knock sensor as well.

A clock tick does sound more like valvetrain.

 

So if is no knock sensor... it wouldn't pick up the knocks and retard my timing giving me very poor performance... right?

 

You have a knock sensor and unless someone programed it out your pcm, your pcm will retard timing if you have vavle tap.
