Quote »why dont you try takin off your cap and starting your car 240under....all it means is that your water pump is working. the cooling system is under pressure, what else can it do but shoot out the cap when you remove it? [/quote]WRONG....have you ever worked on a car before? If the headgasket is fine STARTING the car will casue NOTHING to come out of the radiator, why? casue the water pump isnt moving much water and the system isnt up to pressure. A blown headgasket will, in SOME CASES casue excess cooling system pressure (if the gasket is blown between the waterjacket and combustion chamber) and will force combustion gasses out the radiator....ive used this test to verify/disprove several blown headgaskets, go and try it now, start the car with the cap off...nothing will happen....
Quote »if the headgasket is indeed blown then he water temp will rise. and so, taking off the radiator cap and letting the car warm up will indeed make the radiator over flow.[/quote]like i said before...it wont overflow, it will gieser water out(actually combustion gasses, but it will force water out with it.)....its not from being warm, and sometimes the water temp DOESNT go up (if there is enough coolant).I'm surprised by some of the answers here.
Quote »blown head gasket? why would the plug wire / hole be filled with oil?
it's a bad valve cover gasket, they go bad, they leak into the plug holes, and cause mis-fires.
it seems to be a common thing with 2nd gen probes (KL-03) and the KA engines.. [/quote]
im not surprised, im dissappointed. I came here for advice but it seems me and you know more then the posters on this thread. ANYTIME you have plug-through valvecover design you WILL get leaking on the plugs, My saturn does the SAME thing.
so no...its 100% NOT your damn headgasket....100% valvecover gasket
