Hi all, can someone know if the above pump is it the upgraded one or the old pre 2003 one ?

Any benefits in upgrading it ?

Thanks.

If the tolerances are within spec & the gears/shaft turns freely, you are prolly good to go. I hadn't heard about upgraded oil pumps in these cars.

When I looked up the part # for a '08 and '01 I got the same part # for both years.

There was an oil pump update. I did mine a real long time ago, don't remember the particulars.

Mine is an early 03, the update was in late 03.

True, because Honda will list only the updated one.

What's the difference between the old oil pump and new one

Yeah, this is a bit new to me.

The difference is the that the old one has a rotor with 4 bump and the new one with 6 so more presure si made, but I need to check it next week to be 100% sure, when I'll open both.

One thing I miss on modern cars is an oil pressure gauge.

Reading this you start wondering if you should upgrade the oil pump in your pre update car just as a matter of course. I know we have an idiot light, but boy it would be nice to see a gauge.

I'm curious now if they increased the oil pressure spec for the engine when they did this. Why did they do this anyway?

Was there a recall to install this oil pump upgrade?
Like they did (*) with the oil jets?
(*) or better: they didn't in the US because the "sustained high speed/rpm wasn't much of an issue in the US"
