Ok so i got a 09 motor put into my car.... At Idle cold its 65psi, Idle warm 30-40 but when cruising around and its HOT when i come to a light itll go to like 10psi idle... is that normal or something to worry about? ...


4/24 - Car will not make more than 40psi oil pressure cruising at any rpm..... wtf?

check your oil, make sure its not low. drain it, and see if you can find any metal shavings. if no metal shavings, try putting a thicker weight oil in the car now that its gonna get hot in the summer, see if levels go back to normal. try this first.

my oil pressure is the same and ive never had a problem

ElevationTC

Yea he drained it and had the filter cut open and nothing, he said it runs smooth as hell. when i called toyota they said if it dont goto 5 psi or lower its ok :O

Thats normal, i have similar oil pressure and i was running 5w-30/10w-30 oil. But now since i'm on much higher boost for the next tuning session i'm switching to Motul V300 10W-40

the book calls for roughly 4.8 PSI of oil pressure at idle and 36 psi at 3k rpms ....just so u feel better my car idles at 4.8psi...which is bare minimum, also the readings depend on location ur getting it form,im getting my reading from the sid eof the block which is also where my oil feed is so thats why my readings soo low, another reason is my sender unit is going bad

Yea when really hot I have hit as low at 8ish psi on 5w30. Your numbers sound normal to me.

When car is cruising it seems like the oil pressure wont go above 40psi, anywhere between 3k-5k and it wont go above 40psi? theres no external oil leak that we can see....

so the engine sounds and runs good and everything except for the oil pressure? try using another oil pressure gauge, maybe the gauge is faulty.. not going over 40 psi doesnt sound right, idle seems ok

ya i was thinking it was the oil gauge to but mike said its not... could it be oil pump or oil pump gasket related?

ElevationTC

My guess is oil pump/gasket for oil pump. We will find out soon :O

yeah i think its the closest cause to the problem, just thinking if you can verify the gauge is working well before getting some job done under
