How do i fix oil going into air intake manifold ?

Based on the symptoms you have described, it is possible that you are experiencing issues with both the timing chain and the sensors. It is not uncommon for a low oil level to cause damage to the timing chain, especially in an engine with high mileage like yours. The reduced power and hard shifting can also be related to timing chain issues.
However, the oil leak and oil residue in the air intake tube could also be indicative of a valve cover gasket issue, as you suspected. This could also explain the brown liquid building up in the air intake tube.
In terms of next steps, it would be advisable to address the oil leak first and replace the valve cover gasket. This should stop the oil from dripping onto the exhaust manifold and eliminate the burning oil smell. Additionally, cleaning the air intake tube and replacing the air filter may also be necessary.
Once the oil leak and air intake issues have been addressed, it would be best to address the sensor codes next, starting with the camshaft and crankshaft sensors. If the codes persist, then it may be necessary to look into replacing the timing chain.
Given the age and mileage of your vehicle, it may be worth considering whether it is worth investing in the repairs. However, if the repairs can extend the life of the vehicle for a few more years, it may be worth it in the long run

You have replaced the gasket

Hi,
Symptoms of a bad or failing Engine Oil Pressure Sensor

• Oil Pressure Light comes on, and you check the engine oil level, But oil level is okay, you can blame the false reading on the sensor.
• Oil Pressure Light blinking constantly. This is the normal >check< oil pressure sensor Warning that the sensor is going out.
• If the sensor is giving false readings, Dispite oil level, the sensor could be replaced.

If the Sensor is currently not working, and does not warn you of engine oil level, and oil level gets extremely low, The Engine could burn up/stall due to lack of oil, and may not restart.
Then you could probably blame it on the sensor.
But really would be lack of oil.

Intermittent No Start,
Common causes deal with 3 basic systems/areas of engin

1. Compression, its the build up of air and fuel into the engines cylinders. Then is compressed by the pistons. And is under pressure. FAILURE An Air leak (vacumm leak) will allow pressure to escape.
2. Ignition System, good battery, good relays, wires are not loose or disconnected, good 10volts to starter, 10volts to distributer>gives 20kvolts to spark plugs>has strong spark to ignite compressed air in cylinders. Other sensors need to work. Crankshaft sensor(ccs) Throttle Position Sensor(TPS), +more
3. Air/fuel Ratio, Air Intake Manifold, and Fuel Pressure Sensor *Fuel Injection Pressure Sensor---if car is fuel injected*, air filter is clean and intake manifold hose, Throttle Plate Acuater, Idle Air Contro Valve(IAC). Also vacumm leak cause no start. To much air not enough fuel will cause lean fuel mixter==low power, low idle, no start.......To much fuel not enough air will cause rich fuel mixter==too much fuel could cause engine knock, flooding of engine wet spark plugs, No Start

Hi, I am a 3rd year apprentice 310s auto service technician. You are more than likely correct about your oil level being to high. During vehicle operation gases are produced inside the crankcase. For efficiency and emissions purposes a system is in place that routes these gases through the valve covers, through a hose and back into the intake manifold or air cleaner assembly. The photograph you took is of the post filter section your air cleaner assembly. If there is too much oil in the vehicle it will pool under the valve covers and trickle into the flow of gases being routed back into the intake, you'll likely be experiencing some thicker exhaust smoke especially during acceleration. I would suggest draining all your vehicles oil and removing and draining the oil filter, then refill with the specified amount found in your owners manual; you can catch and re-use the oil. Remove and clean your intake assembly as well. Now go for a quick drive on the highway to burn any oil you may not have cleaned out. Contact me if you need more specific instruction.

I'll explain the part. The manifold runner is like a venetian blind. It is suppose to move to change drawing air into different cavities under the Intake manifold. Sometimes the system works with Vacuum and sometimes with Electric solenoids.
If you see small pods or solenoids going through the Intake, the external solenoid or pod may be your problem. The plastic clip on these parts can break.
Also since your stereo was changed, and solenoids can be Electric powered, someone may have cut the power to the Bank 1 intake runner solenoid when they installed the radio.

The thick rubber hose from the air filter to intake manifold leaks (broken). Replace. Clear compuuter, enjoy

You have a bad valley pan gasket, not very expensive to fix at all, it is located under the intake manifold, happened to me and almost everyone I know that has this truck, goodluck

if it's 5.2 or 5.9 engine,the intake manifold plenum pan gasket may be drawing oil from lifter valley of engine..remove air cleaner and check down inside manifold with throttle plates wide open and look for oil pooling inside intake..if there is oil in there,you to remove intake manifold and replace gasket and bolts holding rectangular pan to bottom of intake..you will need intake gaskets as well..suggest going to dealer for parts..fairly inexpensive as well..i hope this helps

It could be burning and you don't notice. Remove air filter box assembly from top of intake manifold. Hold throttle wide open (engine off) and look through throttle body (flashlight may be required) and see if oil is puddled up inside manifold. If so then the intake manifold will need to be removed so the lower pan gasket can be replaced.

some cars have this problem when the intake manifold is loose or drawing air or the roteror cap may be defect, to check your manifold ,with a cold running moter spray a bit of starter spray (with eather) along the intake manifold , if it's leaking the moter will increase in rpm.
