Spark Plug Broke Off In Cylindar Head
Well, this minor repair sure has turned to **** in my hands. CEL on my girlfriend's 97 Civic DX (D16Y7), pulled the code and it was the upper O2 sensor. Replaced it, reset the codes, went for a test drive... CEL came back on immediately, a few minutes into the drive it started blinking (bad misfire right?). So, I listen to the injectors, they're all clicking, and I figure, well I'll start with the easy stuff and change the plugs. The GF had taken the car to the dealership a year ago for a tuneup, and plugs were changed than (at least she was charged for um...).
Plug 1 & 2 are a little tough to get out, but after a little working back and forth they're out. Anti-seize on, put them back in. Plug 3 is proving to be just as hard, and I give it too much muscle, the threads snap off in the head leaving me with the hex part and all of the porcelain. I've soaked the thing for 2 days with PB Blaster, and have attempted to get the threads out with an EZ Out to no avail. I've put what I think is a lot of force (crescent wrench on the end of a 1/4" extender attached to the EZ out, cheater bar on the wrench) and I don't want to break the EZ out off. What the hell do I do now? I've heard heat it with a propane torch and let it cool a few times, trying to get lube to soak in there and get the threads to release. I've also taken off the valve cover to gain better access, however I don't know how (or if) I can remove the spark plug tube (outlined in red below): http://downtownsb.com/invoice/hosted...civic_head.jpg Where am I at now? I can get a rebuilt head on ebay for $200. I've yet to put in a head, however don't see any reason why I couldn't deal with it after reading the helms manual and some DIY's. Anyone have any ideas, this spark plug has really ruined my week. |
Biggest thing right now would be knowing if and how I can get those damn spark plug tubes off. Having to work 7"away from the broken plug is a total b**ch.

^seen you there also ;) i suggest taken the head off and then you can unscrew it from the bottom, they may have cross threaded it and thats why you cant get it out. |
