shelbyluvv Posted July 22, 2014 Share Posted July 22, 2014 Onyx has devolped a nasty rattle and low oil pressure when warm. I just put a pump in it a few years ago and it still had a rattle and low oil pressure when warm. Before I blow another $50 on a new pump does anyone have a good used pump they would like to part with? I would like to verify that it is in deed a crap pump. I would need it shipped to a PO Box in 31703 Albany GA Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted July 22, 2014 Share Posted July 22, 2014 What brand oil pumps are you buying ? I have a melling high volume pump in my stroker and having the same issue . It has less than 2k on it . I still have my old one that I took out before I built the stroker that you can have for shipping costs ,It had good pressure . But when I tackle mine and go through all that work I wouldn't want to put a used oil pump in . It's a 4.0 right ? Link to comment Share on other sites More sharing options...
shelbyluvv Posted July 22, 2014 Author Share Posted July 22, 2014 I have a Melling HV pump as well. I am not sure if it is bad bearings or lifters but the new Melling pump did nothing to change the way it ran. Granted this was a few years ago when the pump was swapped out. It is not a faulty guage either. You can hear the valves talking when the oil get hot. It is a 4.0 as well Link to comment Share on other sites More sharing options...
