Weird noises

[wd8984]

When ever I put real heavy pedaling to the pedals they make a clicking sound, not sure if the bottom bracket , chairing bolts or what. Any suggestions?

sounds like Bottom bracket. check for sideplay in your crank. swap pedals out to cross check those
post some pics of your bb area

Well I have switched pedals, tommorow I'll check that. And the bb did had some play . It doesn't matter if its little play, it still has to tighten right??
And about the pictures those where the best ones , my tablet doesnt have a rear camera

free spinning with no play is what you want.
remove your bottom bracket clean inspect and replace the bearings.
if you see any pitting then replace.

Ah okay well thanks for the solutions and one last question, if the drive train makes a noice in certain gears like the fourth one out of seven, is that still the Bb??

might be.

Might also be a worn cog (or never used cog with a worn chain).

How can someone check for a worn cog?
