Wow prolly a broken piston, rain water leaks past the windshield cowling and runs down on top of the intake manifold. The intake is loose and the water leaks past the seals and into the engine. As you start you slug a cylinder with water and it hydro locks breaking the piston-rod etc. Good Luck.
I knew it wasn't a bearing.....

Geez I tell ya its not rod bearing noise and i'm right.........hmmm
Sorry next time i'll join you guys in the ITS ROD BEARING NOISE standard BS.
It broke a rod not a rocker, that why it didn't run properly.
If it was a "ROD BEARING" It would have run fine and just knocked....
You guys are so smart.................

I have an 01 Camaro Z28 that sat up for 3 yrs fixed her all up and drove several miles to make sure everything was ok...no knocks no abnormal noises or anything. Parked it and came out the next day to show her more love and this same exact noise occurred on start up. I was cringing the whole time and it ran like complete crap...just like in the video.
Here is what fixed it...gave it a few revs and it went away and the car instantly ran smooth once the tap stopped. To this day after 600 miles it hasnt tapped or ran erratically. I chalked it up to a lifter that wouldnt pump up or was stuck since the car sat for so long.

Yea I had my wife key on and key off the ignition while I held the shrader valve open with a allen wrench until I got clean fuel. That fuel was terrible I thought for sure Id have an injector or two go bad, but the car runs perfect and pulls hard just like before.
