Starter Knocking

i have a 2007 cobalt lt and when it starts fine but after the car starts up for a split second it knocks a few times, its not my motor because my friends dads car does the same thing and he says its the starter, when its running and driving it doesnt make a noise (same with my friends car)

I highly dought its that, if the tensioner was loose it would knock and tick all the time, the car hasn't done in a few days now, it could of been because the car sat at a used car dealer ship for 5 months with nobody moving it to much until I bought it.

Our cars are known for the timing tensioner to make that noise upon start up but then go away. It could very possibly be the tensioner

Tensioner first design loses it's hydraulic prime after sitting. It get's worse and worse until it will make noise everytime you start it up until Oil pressure builds up, but if you highly doubt it's the tensionner I will never mention it again.

if i did have to replace it how much would a new tensioner cost? and for someone who is pretty mechanically inclined, how long would it take to replace it?

Tensioner works from oil pressure. Super simple to replace. Use ecotec oil filter socket to remove it, install new one. Pull ignition and fuel pump relays, turn over a few times, put back relays and then start her up
