Ok Situation is 2 nights ago... I was driving around and somehow the crank pulley Bolt Loosened..the Key pin keeping the pulley and crank sync'd slid out a little then got twisted and the pulley practically separated from the crank and knocked around for a couple secs before i turned off the engine...i get it back home and take a good look at it...
Visible Damage is twisted Pulley Pin Crank Bolt Loose and the timing belt jumped about 4 teeth...So the next day i go to honda get a new Pin and reinstall my spare pulley. After finished there i TDC the Crank and head and put the belt back on...
After all that i go for a mild test drive and everything seems great...feels good and im happy...

Now for the Problem...
Today i get in my car and begin to drive...all seems well and i hop on the freeway...All is good then i get off Its Begins to get hot then all of a sudden i hear a slight knocking noise...and the temp just rises...
So i pull over instantly and check it out...I was low on coolant and my overflow was FULL...So i fill the radiator and i try driving...Drives perfectly fine to me but still the noise...Thing is the noise only comes at low RPM like under 4k and none at all in neutral...

I drive it home on the freeway and it continues...but not getting worse or better...
I get home ok but i still cant figure it out at all...so i listen to the idle and it had a slight misfire like a quiet pop noise every once and a while..

Im so clueless right now...all i can think is maybe when the pulley incident happened it possible messed another component up like a pump on the block...
Or possibly bent a valve but would only 4 teeth off do that?
It doesn't seem to be a rod or piston because the motor still feels somewhat smooth and i currently have no smoke whatsoever from the muffler...

Lets Get some opinions out here please to i cant know where to start tomorrow...Thanks

2 teeth is enough to screw the engine over. i believe you have a bent valve for one, and two something is wrong with the water pump. do you see any leaks anywhere?

 

finally somebody helps me...and yea im having it checked out monday...i drove it around for a while today and it stayed at normal temp...but the RPMS Seem to take for ever to drop after i put it in neutral now...
It also has i slight knock on startup
