Odd Oil Pressure Symptom

Rojoryu

It has an aftermarket one installed. It was not registering any pressure until the throttle was blipped. I cranked up again this morning and it seems fine. I dropped the oil and didn't see anything weird in it. I’m thinking maybe a blockage in the oil passages. I probably went overkill on the RVT when I changed the gallery gaskets.

THE BULL

Well gallery gaskets should not need ANY RTV. I did coat my OEM new gaskets in really light RTV at the same time.

Your best bet is to install a manual gauge or wire up the glowshift manually so it can give you as quick of a reading as possible.
Depending on your findings I would change the oil and filter and inspect the filter as previously stated.

Continue to monitor this.

Thanks for the response. I should clarify. I didn't put any rtv on the gallery gaskets themselves but I did use a lot reinstalling the timing cover and oil pan. It’s plausible that some excess detached and could have lodged itself somewhere. I’ve changed the oil this point, inspected the old oil and filter. I even ran a magnet and a light through the old oil and didn't pick up anything. I used a Harbor Freight external gauge in addition to the one thats already installed and they are both reading normal pressure. I have no idea what was causing it but I will definitely continue to monitor it.

With the analog gauge what is the minimum pressure you see at cold start and for how long until you have to blip the throttle?

Rojoryu

Cold start I’m at mid 90’s PSI. I haven't been able to replicate the problem since the track event. I’m just going to keep running it as is. If something fails I’m OK putting a new engine in it.

That's low, it should be in the 100's. I beat you have an issue with the boundary gears. It has happened before on a new engine build. I suggest you go back to a new Nissan pump or get the Nismo pump. You could also be seeing
bearing related issues. Either way, you have an issue going on.

For what it's worth, the only time I have ever broken over 100 PSI on this particular car is a cold start in the Winter.
