There was an oil pump change, somewhere in 2003 production. Anybody know when this started?

 

My 2000-2004 Honda OEM parts manual shows only two part numbers. 15100-PCX-013 for the 2000-2003 cars and 15100-PCX-023 for the 2004. Usually if there was a mid-year change the parts book will show the new part number begining with a particular engine number.

If there was a mid-year change in 2003, that would be cool by me as I have a late model 2003.

 

My production #is 7544. I always thought the the S2000 had a high volume or high pressure oil pump anyhow

I didn't have time to read all 9 pages of this thread to double check, but it does appear that in 2003 hond gave us a new oil pump. not sure what changed exactly.

In MY2000-MY2003.x we had oil pump part number 15100-PCX-013
and MY2003.x to MY2005 we have oil pump part number 15100-PCX-023.

Can't say what the difference is, but just FYI.


Maybe he'll chime in....

NOW....with the oil pump...I'm going to get my self an oil temp, and oil pressure guage, and monitor temp and psi under different conditions. I have a new pump coming, and I'll monitor the differences between old and new. Off the top of my head, I'm thinking...

-Time to psi on startup
-cold pressure
-hot pressure, and max temp
-rate of temp increase

Hopefully we can see a reasonable difference here, I'll post what I find.

Feel free to add any other parameters you guys feel I should keep track of....

 

cool

 

Oil pressure at a constant 7k rpm as in sustained high speed driving vs normal freeway speeds (65-75 mph). I am interested to see if the new pump will help prevent catastrophic engine failure due to severe driving conditions such as sustained high speed driving.

Ps, Yo billman, don't crash trying to test this $hit out for us

 

I'll try to keep it on all four
