If one is significantly lower, then most likely the head gasket is blown on that cylinder. Compare the readings, they should be within 10% of each other. Have someone crank the engine for 4 full revolutions, or until the pressure on the gauge stops climbing. Thread the compression tester into a cylinder. Remove the electrical connector from the cover over the top of the engine, remove the 4 10mm bolts from the cover, remove 4 spark plugs, remove the fuse for the fuel pump. If you want to check it out yourself, you will need a ratchet, 10mm socket, 6-12" extension, 9/16" spark plug socket, compression tester, and cooling system pressure tester(with an adapter for your coolant reservoir). Low coolant could make the noise you are hearing as it flows through the heater core if it is low enough for there to be air in the heater core. Thanks!įrom what you have said, there is a good possibility that the head gasket is blown slowly allowing coolant into one or more cylinders which makes it start hard once coolant has been able to pool up. If anyone could give me some helpful advice or suggestions it would be much appreciated. Our check engine light is no longer on, but it still sounds rough, is losing coolant, and the sloshing water sound is still there. He changed that and a week later it still hasn't done any good. The check engine light came on around the beginning of all this and whenever we had the mechanic hook it up it said it was a knock sensor. It sounds like water sloshing around in a tank whenever he has accelerated and then suddenly stops. Then just the other day we started hearing a noise under the passenger side. The sound it is making sort of reminds me of when we had to change the oxygen sensors in our old van. Then it started running really rough when starting up. There is no coolant in the oil and none visible on the ground. I don't know if they are all related or not since I know nothing about cars, but since they started happening around the same time I assumed they were. All of a sudden several things have went wrong with it. The engine is a 2.2 according to oil change records (hubby is gone and I know nothing about cars).
