A plastic piece that goes from the oil head gasket to the engine is called?

it means that there is no hole in the head gasket to allow the oil to get to the rocker gear. That means that either you have placed the gasket on the wrong way round or the gasket you have is not exactly right for your engine. Simple check is to remove the cam shaft and see how far a piece of wire can be pushed down the oil hole .

check the coolant flow,you know,how in detail it flows. I had a car,Buick I think, that cooling was entering the cylinders,so I checked in total detail how coolant flows and found out it WAS NOT the head gasket but a plastic piece the covered the valley (covered the top of the engine)and it was broken (from wear??)so when I replaced it (some seals),it solved the problem. I'm glad I didn't take the heads off ,machined them,replace head gaskets.....etc. Hope I helped.

I think you are being led up the garden path here big time ,why because iam almost certain this is the head gasket ,the oil is pumped up to the head to feed the valves and in doing so passes through the head gasket which on numerous occasions on various makes its the head gasket .Some vehicles have a rubber seal around the hole like a seat ibiza and some dont like the focus but with a bit of wear as the motor gets old with over 100.000miles or so the head gasket can and will fail now the only ones that dont are the old morris minor with a copper head gasket .What happens is the head gasket material just breaks down ,the rubber ring in the gasket goes brittle or the material around the feed to the cam breaks down ,All this water in oil and oil in water junk you here so called mechanics blab on about is brown stuff ,this problem can also cause oil to leak out the side of the head and run down the block which its doing on my escort diesel and one day i maight change the gasket when pigs can fly that is of course .No takle the head off clean it up then check its flat with a straight edge and if its ok just renew the head gasket .End of story

If you have the V-8 Engine, just totally disregard this post.

If you have the 3.8L V-6 engine, your oil consumption problem is most likely to be caused by the PCV Valve if you cannot find any external leaks. These are also known for the upper intake plenum leaking antifreeze. The ports in the manifold that go to the throttle body are made of very thin plastic. The EGR tube, with its hot exhaust gasses, goes right between them. This causes the plastic to heat up and crack, causing an antifreeze leak that goes directly into the intake and gets burned in the combustion chambers.

DORMAN makes a replacement upper plenum kit to fix this problem. The kit includes the upper plenum with thicker coolant passage walls, an intake manifold gasket set, a smaller-diameter EGR orifice, and a new PCV Valve. This kit will probably fix BOTH of your problems.

The DORMAN part number for your car is 615-180 Shop around...prices vary considerably.

Often (but not always), a blown head gasket will also cause deposit of water on a piece of cardboard held an inch from the tailpipe output while the engine is running (when this is happening, it is likely that the catalytic converter has been ruined and the muffler will corrode in short order as well).

Sometimes drops of water will be seen dropping from the end of the tailpipe. Another clue: turn on the heater; often when the head gasket is blown an odor of antifreeze and synthetic rubber will emanate from the heater vents.
Many of the symptoms of blown head gasket can be caused by some other problem in the cooling system, without the head gasket being damaged. Conversely, other problems with the cooling system can cause a blown head gasket and/or warped head.

When checking for a blown head gasket, one of the most common tell-tale signs is a milky-gray ring around your oil cap. When coolant enters the engine oil through a crack in the head or through a blown gasket, it evaporates and leaves a milky ring around the oil cap. Another easy way to tell is to check your oil dipstick. Change your oil and pull out the dipstick. Make sure that you take note of how far up the dipstick the oil is. Top off your cooling system and fill your cooling reservoir to the top. Screw radiator cap back on and start engine. Run engine for about 20-30 mins. or until it reaches normal operating temperature. Allow engine to cool (engine must cool completely to get accurate oil reading!!). Check oil dipstick again. If the oil has a watery appearance and has risen noticeably up the dipstick, the you probably have a blown head gasket or a warped head. Also look for a dripping, sweet-smelling liquid coming out of your tailpipe. Any of the above symptoms could be the result of a blown head gasket. The easiest way to tell is with a compression meter. This replaces the spark plug and lets you know what compression each cylinder is running at. If your compression is abnormally low, then you have a blown head gasket or a warped head. (note: consult repair manual for appropriate compression of each cylinder.)

The most likely source of your problem is NOT a head gasket or cracked head, but the black plastic plenum or "upper intake manifold". These GM engines tend to melt, crack, or warp the plenum because of the hot EGR tube sticking up through the plastic.

If water is getting into your oil (milky looking), your lower intake manifold gasket is probably cracked. Once the plenum is off the engine, there are only about a dozen bolts holding the lower intake manifold on. When you replace the gasket, it is recommended to use an ALL METAL gasket with rubber seals to prevent this from happening again. The metal gaskets cost about $80 where as the plastic ones that are prone to breaking cost about $45. Better to fix it right once than to do it wrong several times.

Also, if you are still using Dexcool coolant (orangeish), be sure to change it every two years or so as it does bad things to seals when it gets old.

Hello mspayde925: My name is Roger and I will give you a answer. This could be either intake or head gasket. If it is a head gasket you should be getting white steam from the tail pipe. If it is a intake you should just have coolant in the oil. Most common is the intake gasket. GM put a plastic silicone impregnated gasket on the newer engines. Have a lot of leaks needless to say. Be sure to change the oil after your repairs. Should you need further help please just ask. Please rate the answer you received. Thank You for using Fix Ya. Roger

if thats the case you should have water in the oil also, that means you have a blown head gasket

hello your intake gasket is most likely leaking internally into your engine.pretty common problem.the plastic and silicon gaskets get weak over time.

Check the spark plugs. If it is coolant getting into the combustion chambers the plugs in the affected cylinder/cylinders will have a gray or clean appearance to them.Normal plug color is tan to brown.
