Changed my oil for the second time today, and had the noise happen again. It is a sequence of clicks, probably 6 or 7 and then they go away and don't come back. This happens after the oil and filter have been drained and replaced. Anyone else have this.

 

Only a guess without being able to hear it. Could just be lifter noise until the oil gets pumped up to them. You could try filling the oil filter before you put it on, if youre not already.

 

Do your own oil/filter change and prefill the filter before installing it...I'd be willing to bet the sounds at start-up will disappear.

 

FWIW most engines make a little noise on first start after an oil change. It takes a few seconds for the oil to pump thru the new filter and into the system. It isn't going to hurt anything. There is way more than enough oil already on surfaces to provide lubrication during these few seconds. The only concern would be if the noise didn't go away.

 

You can put some oil in the filter as was said (you should) but the best way to stop that noise and unnecessary wear on start up after an oil and filter change is to unplug the crank position sensor.

This will allow you to turn the engine over without it firing allowing it to build oil pressure and fill up that empty filter. Plug the crank position sensor back in and start it up and there will be no noise. The crank position sensor is located in between the a/c compressor and the timing chain cover, just unplug the connection and pull it out of the way of the serpentine belt and you'll be fine.

 

An expensive alternative, but useful for oil changes, would be to install an external pre-luber oil pump...about $400. And, you change oil by activating the pump from the ignition switch and pumping the oil into a milk jug for future disposal.

 

I am a firm believer in and will not do an oil change without pre-filling the oil filter.

Fill the filter to the top, let it sit for 2 minutes and refill and let sit for another 3 or 4 minutes.

The filter will wick up alot more oil than you may think. Done properly its not messy.

When you start the engine, it will pressurize almost instantly.

Its free and definitely much better for your motor.
