hey everyone whats up i got a problem with my 1998 N/T she's my baby

and iv treated her bad

i let her sit all last winter

i recently moved her to my friends garage and when she is completely cold and i start her she ticks a bit then it goes away after a few seconds but a very faint little tick stays in between the valve cover and the intake mani i was wondering if there was anything i could run through her to clean everything up cause she was sitting so long any ideas? thanks
ps. i hope its not valve tick

colud thi be and why?
