What is your oil pressure after oil cooler install?

DriftKr6l · 07-06-2013, 01:43 PM

Did you pressure drip? If so what was it and what is it after you installed an oil cooler? (At idle and with revs)

Not a lot of people will have an answer for you because almost no one has an oil pressure gauge installed, maybe the FI guys

Not sure if this will help you, but I recently experienced a weird oil pressure drop after a road trip. (I have the Z1 25 row cooler) Generally, when the oil is heated up 90C (194F), I was seeing around 15psi at idle and 30psi at 45-50 (113-122F) degrees Celsius at idle. All of the sudden after my road trip idle pressures are now 15psi at 50C and 7-8psi at 80C.

Don't know the reason for this, however at least you can benchmark your oil pressures off of mine. FWIW I changed to Mobil 1 0W40 at my last oil change and now have about 2500km on the oil.

That sounds really strange. Oil pressure shouldn't change like that unless I'm reading your post wrong.

I had a gauge fail me before, scared the **** out of me when I saw zero pressure. Gauge might be crapping out.

I'll bet. How fast did you get the car turned off and onto the shoulder?

I'd put my money on a failing sender if the pressure changes like that.

edconline · 07-13-2013, 06:43 PM

Hmm.. Thing is the car feels a bit different too, and is a lot quieter than before at given rpms. That wouldn't be a sender issue. Gonna have nissan look at it next week.

Chuck33079 · 07-13-2013, 06:45 PM

Yeah, get it checked out. Something's not right. Oil pressure doesn't just change.

In to see what the problem was..

I have the same pressure before and after oil cooler. My idle pressure after oil is at proper temp or well beyond that is no lower than 35-40psi.

DriftKr6l · 07-13-2013, 10:16 PM

35-40 sounds high for idle at temp. What oil are you running?
I never got that kind of pressure at idle without the cooler.

Im gonna write down my pressures and post them here ASAP.

Mine when heated up is around 18psi.

I have no idea when it failed, but I looked, and pulled over immediately in a 35mph. Checked the oil, the factory light wasn't on so after a minute or two of thinking I knew it had to be the aftermarket failing and continued on my way.

Domestic cars run a lot lower.

I also run about 85psi at about 60-70mph. Which is normal. Sometimes it will go down to 30psi at idle. I run Mobil one but only cause I got 50qts next to nothing.

Maybe it's the location of the sensor. But it's getting moved to where the factory sensor is now for my TT build. Maybe my old location is a issue.

Mine is wired in at the stock location with a T adaptor.
