does this sound like a spun bearing to you?

after seeing this video my motor does sound like this

My oil pressure is at 20psi at idle, 3k rpms 60-65psi. The motor is a bone stock d16z6. If it was a bearing, wouldnt my oil pressure be drastically low? I drove around all day like this yesterday and the sound didnt get worse. it stayed the same. it doesnt sound like anything like the youtube video. what do you guys think it could be?

 

Have you checked anything? Compression? Sounds like me when i had a rod bearing go...ticked ticked...dead.

 

it sounds like a spun rod bearing or bent rod. in your first vid, you can hear the crank grinding really bad.

 

heres another video i took revving it. i hope its not what you say it is =(

it sounds weird like its the valves tapping, but i just checked the valve lash and its on point.

 

sounds kinda like a blown head. any white smoke coming out the exhaust?

 

Rod knock, little end bearing is worn. Rev it further and the piston will hit the head.

i dont know for sure but id say rod bearings as well. sounds like mine before i built it. it doesn't have to get worse right away i drove my **** for like a week before it got any louder.

 

what the hell is a blown head? lol

 

turn your motor on...

as the motor is on start pulling each spark plug one by one.

If the noise goes away on a certain cylinder then that sir is your spun bearing. Drop oil pan afterwards see if there is any damage to the crank. If non no scaring then i would see what bearing color it needs. Or see if an ACL bearing is within tolerences.

only if there is no scaring on your crank.

oh and i would stop reving it and making videos...
