        The oil pump is seized? If that’s the case and the engine was starved for oil, you may just want to get a used or reman’d engine, unless you are really looking for a project (which you very well may be)… But if that’s the case, have you pulled the main and rod bearings? The cam? You will need to inspect for damage at all these critical junctions if the oil pump failed/seized up. What is the history of the car that you know of?

          The oil pump was running with pressure but has seized under hand pressure (i.e i cant turn it by hand) ive looked and theyre in good condition with no scoring or marks and no metal flakes in the oil. the P.O is a buddy of mine who didnt wanna put the money in it so i got a good deal on it.

            Well then, I’ll pass this one on to someone more familiar with Honda motor rebuilds. I will keep an eye on your thread though for learning purposes. Good luck bro 🙂

            Oh, and by the way, welcome to the forums! There are many smarter folks than me that will help you out.

                I’m curious what the deal was with the car when you bought it. No start? Running rough? Etc. Any more info you can provide will help the forum help you.

                    So, the car ran fine but the oil pump was bad? That doesn’t add up. I am not being sarcastic, but how was it determined that the oil pump was bad? Was there no oil pressure?

                      A buddy of the P.O Is a mechanic. he took it in because there was a whining and when he took it in the mechanic told him the oil pump was seizing. my buddy didnt wanna pay the 1+k for it to be fixed.

                        I would have been interested to see what the oil pressure readings were if a mechanical oil pressure gauge was used on this motor.

                        Either way, if the oil pump started to ‘seize’ which would be odd, the engine would be starved of oil so i would expect so excessive wear.

                          Man, this sounds fishy to be honest. I’m not sure how an oil pump could ‘seize’ without severe oil change neglect, or something getting caught in it… I suppose this could be a super rare issue, but this is the first time I’ve ever heard of it happening. There’s not much to an oil pump. Some sort of driver, a belt in your case, and something to create pressure, which is usually two gears that create a vacuum on one side that draws up oil, and pushes the oil forward. I really need some more info. What is a ‘P.O’ by the way?

                            p.o=Previous owner. Its because he took it in right away. it was still turning just was very hard.

                              OK, but how was the oil pump diagnosed? How many miles are on the car?

                                  I’m with Beefy on this one, Oil pumps do not normally (that I’m aware of anyways) seize up other than from lack of oil or neglect in some other area. I’d be wary of what the P.O. and the buddy mechanic said, friends or not. If this thing is starting to seize then there’s probably considerable wear to other parts in your engine too. This is outside my scope or abilities to help but keep us posted on what you end up doing.

                                    This has red flags all over it. In all the years I’ve worked on Honda engines I have yet to see a seized oil pump, think about it, it’s the first thing to get oil in the system so if it’s bad somebody did something to it. That argument doesn’t solve your problem however, given that you have a problem with the oil pump it’s probably a good idea to check out the rest of the engine out to be sure you’re not wasting your money on a new pump as there’s no point in putting a new pump on a junk engine. You might want to put it back together as much as you can and do a leak down test on it to see what kind of shape it’s in.

                                    Was it running when you got it and if so did it sound OK? It would have been nice to know what the oil pressure looked like when it was running IF it was running.
