Drove the car yesterday with the air on and it drove fine down to crown center was driving back and pull in to a parking lot heard a loud ticking and then a loud knocking noise after my husband said he open the Hood and it was hot he could barely touch the oil stick but the temperature gauge did not read hot it stayed in the middle like it normally does tried to let it cool then drove it home the sound was still there seemed to get louder as u drove. Parked it and let it set tell the next day. My husband started it and the sound was still there. WE TOOK the manafold top off and there's one cylinder that is dry on the lifters the two front one's wiggle around but the back one is solid don't even move a little the oil level was where it should be. Doe's this sound like a pully are a blown engine it runs just alot of noise coming from under the hood please help

This is a tough one not being there to actually hear it. Is it a ticking or a knocking? Also, is it the valve cover gaskets that were removed to see the valves?

We did remove the vavle gasket we can see the lifters on the passanger side there oily like there suppose to be but two of the lifters in the front have space unlike the one in the very back that is solid and don't move they move and when you move them the make a metal to metal sound like clunking the front cylinder is bone dry but the other two are oily I believe it the number one cylinder the oil was good no sludge my husband said it sound like a baring is bad we've Google it and got tones of different things it could be we YouTube it and found a video of the exact car making the same nose they said it was a idler pulley it didn't happen tell we ran the air conditioning for the first time this year. Should my husband leave the manafold top off and start it to see if the oil is pumping where it needs to be and how would he test to make sure the Water pump is working and the heater core is good he said that when he started it today the your day went from cold to about the middle in like ten minutes is that normal

I need to confirm something. Is it the manifold that is removed or the valve covers? As far as the idler pulley, just remove the serp belt and see if all belt driven accessories are free moving and don't have excessive play.

My 2001 Chrysler 300m is doing the same thing. People saying it's the motor. I don't what it is. I like to know what it could be.
