my engine has all the symptoms of a bad chain tensioner, now that i know i will replace because i have been wondering why it was making so much noise on start up

it has done this for a while will a bad tensioner do any damage to the chains or sprokets or will it just break them

should i replace all the sprokets and chains or will a tensioner solve the problem

my car has done this for a while and now im going to fix, but do i need to replace the sprokets and chain or should the tensioner be enough because it has been like this for a while

A bad tensioner can cause broken rails, and worn chain and sprockets.
Get it changed soon.

To check the sprockets pull the valve cover (very fast and easy, and no gasket required) and look at the cam sprockets, if the teeth are sharp, time to do the whole assembly (rails, tensioner, chain, and all sprockets)
