Camry Duel Cam Oil Pump on a 22R

I blew the motor in my car and my husband is rebuilding the motor.

It ran out of oil pressure, spun two rod barons, Mains were good, crank is standerd, rods turned 10s.

He sees one baron that looks like it spun a little bit on the front of the duel cam pump.


He is having me to ask if there is a need to change out the Duel Cam Oil pump that is under the crank shaft? What does this duel cam do? what is its function? does it balance for the crank shaft, what is the defects of it? Whats its purpose?


He said the oil pump is picking up oil, but have been advised to change out the Duel Cam pump do you feel this is needed to be done and why.

Thank you for any help.

See note for other question.
