hi ! look i have a 2003 explorer 4.6 liter
Problem !
installed used motor, had issues lining up flywheel , but got it in , started motor and it sounded so good , cut off . And finished tighten bolts to exhaust and did oil change, checked other fluids ,also . then started it up and heard a slight knocking sound so cut off checked again and dash board had no pressure on oil , so cut off and scanned truck no codes, so checked the wiring and sensor (oil pressure sensor) was not plug in ,by oil filter . So pluged it in and started motor again and heard the knock . it is not , very loud but i can her it , sounds like something is turning and hitting something . motor runs very strong,no misfires, runs perfect,except for that knock, can anyone tell me what i should do .NEED TO KNOW ASAP, LIKE 2 DAYS AGO ASAP , PLEASE HELP .
