When does oil pressure return to normal after a cold start?
When does oil pressure return to normal after a cold start?
Once the engine has warmed up the oil pressure returns to what could be considered “normal”. After the cold start, no oil pressure problem, the engine and the oil pressure is fine for the rest of the day.
What to do if your car has no oil pressure?
Once the engine has warmed up the oil pressure returns to what could be considered “normal”. After the cold start, no oil pressure problem, the engine and the oil pressure is fine for the rest of the day. Let it even set overnight though and I have a repeat no oil pressure with start up.
How does a cold start oil pump work?
The pump cannot begin to deliver oil or generate pressure until; it has sucked up oil through the screen and the pick up tube. Hence, cold start lubrication is greatly assisted by having a short; wide pickup tube and oil that has very good cold flow properties.
Why does my oil pump have no pressure?
Another possibility if you haven’t actually checked the oil pressure with a mechanical gauge is that the sensor is gummed up and sticks for a bit on the first cold start before it begins measuring properly. Thought all oil pumps had relief valve for cold starts? Cold oil is thick, high viscosity.

Why does my Cadillac have no oil pressure?
Cold oil is thick, high viscosity. Oil pump goes into bypass mode at start to allow oil to bled off and prevent filter from rupturing. Cadillacs are known for bypass sticking and losing oil pressure. Even an empty oil filter (faulty anti-drain-back-valve?) shouldn’t take a full minute to build pressure.
When does oil pressure come up does the engine Rattle?
(It comes up instantly, not slowly.) The engine “rattles” until the oil pressure comes up to normal. After the engine has been run, the oil pressure comes up within a second the rest of the day. (No rattling) Does the oil pump have to stay primed?
Can a Chevy Silverado lose normal oil pressure?
Until you know exactly what’s going on beneath the hood, you should assume that the warning light is correct and that your engine has lost normal oil pressure. If this is the case, your Silverado can be severely damaged if you continue to drive despite loss of engine oil pressure. Figure 1.
Why does my GM Truck start so cold?
Look up piston slap to study it more its mostly from the short piston skirts that allow the piston to rock around more when cold. Also different oils help, i run moble 1 truck 5w30 in my truck with 116k on it. I have heard that gm top end cleaner and the 3m kits work well.
