Cracked intake manifold...
Intake manifold is leaking, or worse, cracked cylinder most likely tho, the intake manifold.
Don't generally see an intake manifold go bad, it is usually the intake manifold gaskets that go bad in which case you may see engine coolant leaking out in the corners or worse case leaking into the engine and mixing with the oil.
Intake manifold at top of engine?
if it is a vortec, there is a fuel line under the upper intake that goes from the manifold to the injector. check it for cracks and leaking or the injector itself. EGR Valve
on intake manifold
It is inside the upper intake manifold. It is attached to the fuel injector poppets with a bracket. To inspect/replace you must remove the upper intake manifold.
Most likely the intake manifold gasket is leaking.
Intake manifold gaskets are leaking, intake manifold is warped.
most time it is caused by intake gasket failure
It is located under the upper intake manifold.
leaking gasket try tightening the bolts a little might help
Usually when you leak oil that's an indication that the intake manifold gaskets need to be replaced or your intake manifold is shot.
If it is leaking from a bad head gasket, it is because of a bad head gasket. If it is leaking from a bad intake manifold gasket, it is because of a bad intake manifold gasket.
If really on top then probably the intake manifold gasket ,study it closely .
It would be very unlikely. Fuel injectors give very little problems.
To remove the cover box to get to the fuel injector on the 2002 Envoy, first remove the intake manifold and the valve cover. You can do this by loosening the four bolts that hold the intake manifold first.Ê
What's under the intake is not a hose, it's a pipe which a hose attaches to behind the intake manifold near the firewall. If the hose is leaking, it's a relatively easy task to replace it. If the pipe is leaking, you will have to remove the intake manifold which is not an easy task (minimum 6 hours to remove and replace the manifold!)
I just had the intake manifold gasket replaced on my 96 century yesterday and my bill was $450 but my gasket was only leaking out. If its leaking into your oil it may be more.
You have what is called a spider fuel injectors and it is located up underneath the intake manifold. You have what is called a spider fuel injectors, that is located under the intake manifold.
Most of the time - yes
The fuel injector would be located on the fuel rail up under the intake manifold towards the side of the engine.
It is located under the upper intake manifold. The bank of injector poppets are also known as the spider.
motor leaking check intake manifold really cheep gasket from the factory
you need to replace the intake manifold gasket.
