Hey guys
i have a rb Tomei oil pump I’ve purchased used. And is hard to turn… as in couldn’t turn the gears by hand. Installed spool billet gears this arvo and doesn’t turn by hand aswell. Does turn when dummy fitted on the crank with no binding just has resistance. I’ve only delt with factory pumps. Is this normal?? Inspected pump housing and it looks basically like new. Thanks in advance!!
