Normal Oil Pressure in the Block, 2PSI Oil Pressure in the Head
I was testing my new motor the other day, when I noticed that the Vtec wouldn't come on.
I tested the Solenoid, it check out fine. I also check the Vtec Oilpressure switch and it was clean.
So I decided to rev the engine and click the VTEC solenoid manually. Well I heard the solenoid clicking and it trying to work, but It just wasnt working correctly.
My oil pressure in the block was 80 PSI at warm up, and it would hit almost 100 psi at WOT. Which I thought was a bit to high. I thought it was my cheapo Sunpro oil gauge so I got the AEM digital gauge and plugged it into the head.
The results came back a 2 PSI in the head. I immediatly turn the motor off, and thought **** this sucks.
So I pulled the oil pan off looking for any sign of blockage in the Oil screen, and there is nothing. I looked around the bottom of the block, for any broken shavings that would result of a direct result of oil pump failure.
I did not notice anything. Same thing when I removed the valve cover to inspect the head. Clean.
Since the screen in the oil pump is clean, Im guessing there is a clog somewhere, or the oil pump is bad.
But before I do that, I would like to verifiy that there is no clog. How can I do that.

As Im looking at the oil flow chart in the Helms, if the Oil pump was actually bad there would be no oil pressure at all, correct.
The oil flow goes from the oil pan, to the Oil filter to the oil cooler and than it splits in 2 directions. 1 is to the Block, and the other is the head.
What can I use to snake through the oil orifices.

Did you check the pressure at athe sealing bolt near the water outlet? There is only oil pressure at that port when the VTEC solenoid is activated. Apply 12v to the green/white wire.(it wont hurt anything) You should have oil pressure at idle.

Yeah well I hope I just did a noob move here and did that. But I was going through the helms and I was pretty sure it said to take the pressure there.
Now I have to wait until tomorrow for a new oil pan gasket to come in.

Do you have an oil control orifice installed in the block?

Re: Normal Oil Pressure in the Block, 2PSI Oil Pressure in the Head
I double checked the Honda manual this morning. There should only be oil pressure at the VTEC test port during VTEC operation. On this engine, oil pressure comes the main galley up through the center rocker girdle. There is an o-ring between the block and girdle. but I dont see how you could lose 70 psi of oil through an o ring groove. But never say never!

This is quiet posiblly the stupidest thing I have done in a while.
I managed to put everything back, and I turned the car back on and manually connected the Vtec solenoid and poof, there it is oil pressure.
Man I feel like a retard. I wonder if autozone has any job openings.

Its probably fine. I jump the gun to much and assume the worst sometimes. I did that before when my swap wouldnt start. I took apart the whole wiring of the car, and rewired the whole car up, just to find out that the dizzy was bad form the start, ahhaaha. Talk about talking the Hard road.
I also have a CEL code that might be preventing it from working. Thats why Im looking to get some sort of Vtec controller or tuning system.
Change an oil pan gasket, get a job at a honda dealership. Phft, Hahaha. Im self employeed at the moment, and wouldnt have my life any other way.
Although I might go after that Honda Certified technician exam one day, but you really have to know ALL honda engines and cars for that. That would be cool to rub in peoples faces.
