Obviously a blown head gasket is causing it. Junk it, or fix it. I wouldn't put a lot of cash into a 20 year old vehicle.I have a 87 Dodge Raider w/ blown head gasket I am getting bubbles out of top of radiator %26amp; oil fill holes?
Blown head gasket.
When your engine runs, the piston goes up and down (like a bicycle pump) Every second time that it comes up it is pushing against the head(as the doorways to let the gases out or in are closed. This is the compression stroke. Once the piston reaches the top the spark plugs fires a spark and ignites the compressed gases above the piston(which are about 160PSI) The ignition creates an even higher PSI- your power stroke and the only movable object there is the piston(that just came to the top) so now it is hammered down to the bottom of its travel in the cylinder and then a doorway(valve opens) to allow the burnt gases to escape into the exhaust pipe. The driven piston bounces back up because it is forced to by the crankshaft rotation and it pushes out all the burnt gases, ...the second time the piston heads down the exhaust valve closed and the intake valve opens to allow some fuel and fresh air in. Once the piston is at the bottom, the intake valve closes and the piston is on a compression stroke again. If the engine idles at 1000RPM the one piston fires 500 times a minute. And there is 4 pistons in a 4 cylinder, so that means there is 2000 compressions against the head in a 4 cylinder in one minute.
If you have a leaking head gasket, compression is leaking past the gasket which normally seals tight the head to the engine. The compression is now into the cooling system(which cannot handle that high pressure with just rubber hoses and plastic parts, and leaking into the oil system which has only cork or rubber gaskets. Again, not able to handle the high compression pressure. Your engine starts to leak oil alot.
Solution Only 1. Get the head gasket replaced and torqued down properly. Go to the dealer. This is not a backyard ';yeah I have a crescent wrench and can feel how tight it is suppose to be'; type of thing. There are 10 to 14 bolts that need to be tightened down all the same tightness.
