2012 Prius pumping rattling sound after cleaning intake manifold, EGR valve, and EGR cooler.

So I started with engine knocking and went onto the adventure of replacing the spark plugs and coil ignitions.

then I went onto the intake manifold and EGR valve.

the knocking still persisted so I took out the EGR cooler and cleaned it out.

I put it back together today and it runs perfect besides one issue.

the issue: For some weird reason their is now a pumping sound that is going on when the hybrid battery is recharging.

when I put the car in reverse and the engine kicks on, or the battery is recharging the sputtering kicks on.

did I just forget a hose? I mean if I did wouldn’t the issue turn into a check engine light?

I also hear a major liquid flush behind the driver side when turning on the AC system or the hybrid battery charge kicks on which was not there before.

I recorded a video but it won’t let me post it here because it says the URL needs to be removed to post the thread.

 

Along with that pumping sound there is smoke coming out of the exhaust. Prior it was not like this before cleaning everything like I did.

I posted a short video of it. But so far it won’t let me post the link here.

it only comes up when the engine battery kicks into its recharge.

 

I will check that out and see what I can make happen.

 

I’m adding the video to my post so everyone can see it. I think I am no longer in moderator block

 

UPDATE

Here is the video of the pump sound. While driving it’s not there. Sometimes it is not there when the recharge comes on.

if seems when the battery recharge is low and it’s kicking on the sound shows up.

As of right now the issue still persists. Car runs normal but can’t seem to find any data online to link the issue or what it may be.
