uhhhh ok my car is making a knocking noise like it needs oil but i put oil in and it sounds the same. i dont think its a engine knot or anything but i i dont know what to do cause its kinda my only ride right now and i need to get around town and im short on cash so if i need to fix something how much is it gonna cost me

 

those are the valves.... hmmm... if you want you can fixed them... but basically wouldnt do diff... i had the same problem with my car later i put sum lucas oil and now only does when the car is cold.... now if you're talking about.... something else like your valves aint seeling... then defntly get them fixed..... spec a little more.... car,year, only does it on cold or hot or all the time.... etc
