Default Hi, I have a question because I do not know if it's a problem or not.

I bought a 2004 350z but when I turn it on the oil pressure is 50 but at 5 min it goes down little by little and stops when it is almost 0 if I accelerate it goes up a bit but then it goes back down that is normal what happens or has a problem and if so, what could be the problem and what solution could have

It's normal for oil pressure to drop as the engine warms up and the oil thins a bit. It's also normal for oil pressure to rise as the throttle opens and more load is put on the engine. You don't list how many miles are on your Z, but it's possible the oil pressure sender is defective after all these years. The only way to know for sure is to bring it to a qualified Nissan tech and have them check oil pressure with a external gauge.

that is a very good answer

IMO
get under there replace the oil pressure sensor and report back with results

Per the manual, idle pressure should be no less than around 14psi. If your gauge is hovering around 0psi you either need to replace the oil gallery gaskets because they're leaking, or there is an issue with the oil pressure sensor. Hopefully it's the latter because gaskets are going to be costly unless you do it yourself.


*edit:


Just now seeing you said 04, I'm not sure if the DE motors had issues with the gaskets like us HR guys do.

Many carguys swaping their car, sometimes between JDM cars, sometimes it's only about germans. Some of them trying everywhere; having a musce than a Japan etc... Thoose people usualy still looking for their "bonds" or can't stay for a long with one car - needing somethink new every few years. That's what in my personal view is: sad...
What I believe, is every car guy should have his own loved car, taking care of this model for decades (like for a pet - make sure this model will survive to show it after 40 years). Indeed he should allso have another cars, like to follow all new performance technologies, turbos, V8's etc. But still he should have his own "oasis" of perfection.

My story start with Mazda 323F from 2001. BJ version after lifting, with 2.0i DOHC engine. In states, You call it Mazda Protege5. I bought it because I was allready Japanese fan and my family told me it's good car to buy as a 1st one, because it won't use too much fuel, it's easy to repair and it won't make any problem. Indeed after a few years I fall in love. It has only 131PK but still, with such light body it has a small "claw". I drove the car arround 6-7 years and I had an accident. At trafic lights the guy totaled my Protege.
Thoose time's i had just 2 weeks to buy another car withour rly supreme budget. I couldn't find nothink special from Type-R badge or nothink royal like Skyline or Silvia... All my friends was BMW fans (and indeed as a young kid i wanted to have a e46 Coupe), they was pushing me to try a german "machine". Because I couldn't find nothink good from JDM cars in thoose 2 weeks I tried a e46... Now I'm 4th year with my 328Ci and I'm absolutely love it. Way it looks, way I'm feeling sitting inside. At the begining I had alot of nervous for this model because it didn't handle like JDM cars. It cost quite much to "glue" this 328 into the asphalt but after good wheels, with branded tires, coilovers, joints etc; it start to drive like i wanted to.
At this moment I'm pushing to finaly install a turbo and wide body kit (Rocket Bunny), but to start, I need another car to drive me into work, shop etc.

Here "Zed" began...
Since I realy was a kid, from all car's I've ever seen - I mostly loved to have 350Z. In thoose time's I was too Young to have a driver license, even if - I couldn't afford of having it. I never sit in this car, I never drove it but from all materials I've ever seen about the "zed", i knew that's the one I want to own; when I'm going to be an adult.
After all of thoose years, I'm nearly 32 and I can easily afford old Nissan. During searching for one for me, I was testing (1st time in life) several Z's: bad, good, cheap, expencive and there's one thing I have to admit: I didn't dissapoint on this model. It is like I thought, that's the car I want to have, period.
I'm still bussy with buying it and I can't find one I want to own, but there's going to be a time...
At the end I just know I want to have a Rocket Bunny e46 and Rocket Bunny 350Z; one with angel eyes, another with demon look. If You like phantasy it's a bit like having one car which is subtle, kind but still with a "claw" for his driver and another one: a gore brute to rape the asphalt at midnight runs.

Hi Larry. I have a 2003 350z, and was experiencing the problem you describe. I changed the oil pressure sender, and that fixed things. I would do this first since it is the least costly repair. I always advise against just throwing new parts at a problem, but it's justified in this case because the part is inexpensive and the success is very likely.
