One of my lifters were ticking at 2000 RPM. I put a bottle of Engine Oil Supplement (EOS) and was wondering if the ticking will go right away or does it take some time before it really kicks in (Like a week or 2)?

 

once the engine warms up you would notcie but it prolly wont help.

 

Most engine additives are snake oil. I'd do some research before adding "fluids".

 

Should i wait till i get an LT4 hotcam kit or replace the lifters now?
