Hey guys I’m stumped, picked up a 02 rsxs had a small oil leak and wasn’t really hitting vtec, the oil was leaking somewhere behind the left side of the motor, I also had a cel for camshaft position sensor circuit A, I replaced the camshaft sensor and replaced the whole vtec cylinoid, it feels like it’s pulling a lot better and smoother but still not quite 100% , I got home and noticed it’s leaking oil again around the same location but Dosent seem to have any on the cylinoid I replaced, the check engine light came back on for the camshaft position sensor I just replaced as well, I’m stumped like I said but I’m thinking maybe it could be the oil pressure sender as it looked like it was a little wet from oil, any help is appreciated I added a picture for the code that I replaced already

Left side when looking at it from the front or left side when sitting in the driver seat? Pictures would be helpful. If it's back passenger side of the engine it could be the VTEC solenoid assembly, oil pressure sensor, or oil filter. You should clean everything really well then start the car and see if you can tell where it's coming from.

Was it an OEM part or one from a parts store? In my experience these only like OEM sensors.

How many miles? You may want to check engine timing.

It’s on the left rear of your looking at it from the front, already replaced the vtec solenoid assembly and the camshaft position sensor was denso, same company that they use from factory

It has 300k, which is a lot I know but I runs smoother then other rsx I drove with half the kilometres, that’s why I think it’s not off timing , other then the small oil leak it runs good besides going into vtec it Dosent seem to fully engage and it rev limits itself at 7500 instead of 7900-8100

Since you mention kilometers I'm going to assume that 300k is also in km (186k mi). I would definitely check engine timing. It's not too difficult to do. You have to remove the valve cover but that's about it.

best bet is to clean it up and look for where it's leaking. Some of this may help speed up the process https://www.amazon.com/Liqui-Moly-20228-Generation-Fluid_Ounces/dp/B076ZNRK12 as it will allow you to shine a UV light and see exactly where it's coming from.
