Sounds like you need a intake manifold gasket replaced it will cost you a couple hundred to have someone do it for you but if you have mechanical ability you can do it yourself if the coolant is in the oil you will want to get it done very soon because the coolant will wash the bearings in the lower end then costing you alot more. any other questions just ask.

My 2008 Chevy uplander engine light on and the code shows for cam shaft sensor and intake manifold what I do


The intake code means its leaking from the intake,bad gaskets, or a vacuum leak. check for bad gaskets on intake manifold. You can tell by putting a bit of oil around the maifold. if it is leaking the engine will flair up. To check this, External leak-- Coolant seeps through the broken intake manifold gasket to the outside of the engine. If its bad enough you will see coolant dripping from gasket. Coolant seeps through the damaged gasket to the inside of the engine, mixing with motor oil. If you suspect an internal leak, check your oil dipstick. Or if you have a substance under oil filler cap that looks like a milkshake, Oil is mixing with coolant. this means intake gaskets are bad, Now for the camshaft sensor, If you have a manifold leak. this could be giving you a false camshaft reading! Because, If sensor is bad vehicle will not start unless theres a wire problem. Symtoms of a bad sensor are--- engine sputtering, poor acceleration, stalling/inability to start. HopeI helped you out! Good-Day!

What is code 22 in a f350 Gas engine


Manifold absolute pressure (MAP) sensor circuit out of range. The MAP sensor measures the air pressure inside the intake manifold. Vacuum is created there and maintained in a running engine (so pressure inside the manifold should be lower than outside air pressure).
If you put a vacuum gauge on a manifold vacuum tap, and have a reading of less than 17-22 in., with the engine idling, you probably have a vacuum or air leak, and the sensor and its circuit is probably good. Or you could test the circuit if you have a voltmeter- then either the sensor is bad or you have a vacuum/air leak.

How to clean intake on 2001 vw beetle diesel


Hi Jay, What do you need to clean and why? If the intake is fouled with oil it would seem to me that the turbo has become defective and is leaking oil into the manifold. Let us know what the problem is and if you want to clean the outside or the inside of the ducting and manifold? there is a great big difference. Regards John

01 durango leakiing coolant nea trans and inside of vehicle


Leaking inside sounds like the heater core. If the core is broke right where the heater hoses connect, it might be losing coolant down both sides of firewall, inside and outside. Otherwise, look for a leak at the intake manifold. That might run down back of engine near the transmission, as you indicated.
Good luck.

You blew a head gasket. Remove the head and see if you can see where the gasket failed, have the head shaved and replace gaskets.

Where is the engine coil on a 97 astro van...?


The ignition coil is mounted on the intake manifold near the distributor.
Remove the dog house, or engine cover and it will be on the right side.

My daughter's 1997 Saturn is leaking coolant and overheating..


Coolant leaks can occur anywhere in the cooling system. Nine out of ten times, coolant leaks are easy to find because the coolant can be seen dripping, spraying, seeping or bubbling from the leaky component. So open the hood and visually inspect the engine and cooling system for any sign of liquid leaking from the engine, radiator or hoses. The color of the coolant may be green, orange or yellow depending on the type of antifreeze in the system. The most common places where coolant may be leaking are:Water pump. A bead shaft seal will allow coolant to dribble out of the vent hole just under the water pump pulley shaft. If the water pump is a two-piece unit with a backing plate, the gasket between the housing and back cover may be leaking. The gasket or o-ring that seals the pump to the engine front cover on cover-mounted water pumps can also leak coolant. Look for stains, discoloration or liquid coolant on the outside of the water pump or engine.Radiator. Radiators can develop leaks around upper or loser hose connections as a result of vibration. The seams where the core is mated to the end tanks is another place where leaks frequently develop, as is the area where the cooling tubes in the core are connected or soldered to the core headers. The core itself is also vulnerable to stone damage. But a major factor in many radiator leaks is internal corrosion that eats away from the inside out. That's why regular coolant flushes and replacing the antifreeze is so important.
oses. Cracks, pinholes or splits in a radiator hose or heater hose will leak coolant. A hose leak will usually send a stream of hot coolant spraying out of the hose. A corroded hose connection or a loose or damaged hose clamp may also allow coolant to leak from the end of a hose. Sometimes the leak may only occur once the hose gets hot and the pinhole or crack opens up. Freeze plugs (casting plugs or expansion plugs in the sides of the engine block and/or cylinder head). The flat steel plugs corroded from the inside out, and eventually eat through allowing coolant to leak from the engine. The plugs may be hard to see because they are behind the exhaust manifold, engine mount or other engine accessories. On V6 and V8 blocks, the plugs are most easily inspected from underneath the vehicle.
Heater Core. The heater core is located inside the heating ventilation and air conditioning (HVAC) unit under the dash. It is out of sight so you can�t see a leak directly. But if the heater core is leaking (or a hose connection to the heater core is leaking), coolant will be seeping out of the bottom of the HVAC unit and dripping on the carpet. Look for stains or wet spots on the bottom of the plastic HVAC case, or on the passenger side floor.
Intake Manifold gasket. The gasket that seals the intake manifold to the cylinder heads may leak and allow coolant to enter the intake port, crankcase or dribble down the outside of the engine. Some engines such as General Motors 3.1L and 3.4L V6 engines as well as 4.3L, 5.0L and 5.7L V8s are notorious for leaky intake manifold gaskets. The intake manifold gaskets on these engines are plastic and often fail at 30,000 to 80,000 miles. Other troublesome applications include the intake manifold gaskets on Buick 3800 V6 and Ford 4.0L V6 engines.
INTERNAL COOLANT LEAKS
There are the worst kind of coolant leaks for two reasons. One is that they are impossible to see because they are hidden inside the engine. The other is that internal coolant leaks can be very expensive to repair.
