Help oil pressure issue!

so i know out engine are going to be around 60 when the engine is at 2000 rpm but i just did a freash oil change and all and mine will go to 60 at 1000 rpms and hit about 90 all the way to red like,could the problem be to much oil or what im stumped

Mine stays around 90 its always done that. Aslong as its not at 20 psi your O.K.

I would still check to see what's up. First check the pressure sensor. Use a mechanical gauge and see if the readings are similar. If they are then you need to investigate further. If the mechanical gauge reads OK then you know it's just the sensor.

i mean what could it be,i know its bad for the pressure to be to low but i never heard about it being hight but i just replaced the sensor not to long ago but it seems fine but ill check it with a mechanical one

Re: Help oil pressure issue!

If the pressure really is high, It's probably the pressure regulator, which I think is part of the oil filter adapter assembly, but others on here would know for sure. If the pressure is at 90 that's not too bad, it will probably not harm anything. I wonder if the oil filter could have something wrong with it. I don't know if the pressure sensor is before or after the filter, but you may want to change it just to see. It's cheap, and it seems odd that right after your oil change you suddenly have high pressure readings.

I changed mine the other day, but I've ran at 80-90lbs always.

Re: Help oil pressure issue!

Are there any other signs of [exceedingly] high oil pressure? Is this the original sending unit or a replacement? If it's original, it could be going bad. If it's a replacement from a parts store, those are known to read a little high.

Re: Help oil pressure issue!

Did you use something other than 10-30?

Re: Help oil pressure issue!

5w 30

Re: Help oil pressure issue!

I've used 5-30 & 10-30, same pressure..

Re: Help oil pressure issue!

Could be your sending unit. I've had those go bad before, they'll send up some nonsense readings. But like others have said, as long as youre > 20psi don't lose any sleep over it.

Most likely it's the oil pressure sensing unit. It's simple to replace, right up front on the block.

If the engines not knocking and sensor isn't leaking don't worry. Had same problem as you and did sythetic oil changes everytime it started get black now at slightly over 60. Currently running mobile 1 extended performance 15,000mile oil change filter at 5000 because it was getting black then added 1/2qt cleaned right up and still good oil pressure and less oil consumption than when I bought the car.
