Bike crankset is clicking when pedaling?

[ethan]

So I just got a fixie, and I already had to replace the crankset but I got that some out of town cause I don't have a bike shop here, but now the new one is clicking when I pedal hard or resist on them to slow down, and I can't take it to the bike shop out of town, but I heard it could be a tight chain or the crankset could be loose, and I loosened the chain good enough, and I tightened the cranks with an Allen key, but it still clicks? What can I do? Please help

Most likely it is the crankcase bearings.
