I'm pretty sure i've got a really bad water leak. the front two sparkplugs i just took out were corroded as hell and had spots of rust. it's hard to start then idles rough before smoothing out. not positive if it's blowin white smoke as it's kinda cold right now and it would do that anyway. it also keeps blowing coolant out into the overflow. tried two different radiator caps, but it still keeps blowing out the coolant, and eventually overheating. i also replaced the coolant level sensor, the old one was melted, hopefully from the overheat that took out the first engine( my cat collapsed and it got real hot real quick.) i just drove it for the first time in 2 weeks today(tags expired because it hasn't run well enought in the past year for me to get it inspected.) now it idles fine, after it sputters for a few seconds, but i have no power and it's making this chattering noise when i push the pedal. it also stumbles constantly when i give it gas. if anyone has any ideas please tell me.

 

this is the part where someone tells me "Don't worry, your problem is actually something obvious that you never thought of and is really easy to fix."

 

Sorry to say, but my friend had the exact same problem, and it was water seals Gonna have to do a rebuild, it got worse and worse and finally one day he popped his apex seal.
