So, I'm helping a close friend perform a K swap into an EG. We're just about done with the swap, just figuring out why it won't start. I remove all spark plugs to inspect them and upon re installation, spark plug at cyl #4 decides to strip right as I'm torquing it snug; it suddenly just gives out and it feels like hte spark plug broke off in the head. I pull out the spark plug via. magnet and notice the whole piece of threaded area is completely missing then it sets in and I see what happened...
the whole coller portion of the sparkplug is totally missing and stuck in the head.
My question - can i remove the stuck threaded piece from the head without pulling the head off? maybe get a long ass tap n die tool??
A large dia easy out should get the rest of the sparkplug out.
As far as any possible debris entering the combustion chamber it would almost be cheaper to purchase a video camera with flexible neck, basically a bore scope, at Home Depot from Milwaukee tools. http://www.homedepot.com/webapp/wcs...og.beans.EndecaDataBean@72cd9610&ddkey=Search to look for any debris rather than pulling the head....
be carefull with an easy out. because when it tries to grip it may swell the threads on the plug out into the threads in the head. this happens to us all the time on yamaha jet ski's. we pull the head and use an allen wrench with a dome cut into it in the center. this makes a cutting surface. pound the allen into the plug from the backside till it is through the plug. then put a socket on it and hit it with the impact. should remove the plug.
best of luck. id stay away from an easy out.
had a couple problems like this. i just used a easy out. majority of the time that it happened on the cars i worked on, the porcelain portion of the spark plug just came out. hopefully u come out lucky.
this happened to me on my B series car....I welded a extention to a big easy out and did it like that. i was lucky the white part of the plug came out perfect and just left the threads.
I just realized i left out some detailed info as i made my first post half asleep this morning at 3am..lol
I wish I had the plug with me to show a picture of it, but luckily the white porcelain tip is completely intact. Just the threading section of the spark plug body is the part that broke off and is stuck within threading of the spark plug hole. No small pieces broke off either.
The previous owner of this motor tightened the phuc out of all the spark plugs too! I had to use 'tard stenf + leverage to remove them plugs from the head. When I reinstalled #4 cylinder snug into the head, it suddenly became real loose, as if i stripped the head.....my jaw dropped to the floor in terror....pulled out the plug and thats when i saw the missing threaded section :down::down:
I'm going to pick up an extractor and start with that first and see how that goes..I really don't want to pull the head, but if it comes to it, we will..also some anti-seize ftw
thanks..
but this IS the first time the plugs have been removed by me/us for this particular K20A2. My friend just bought this swap about 2 weeks ago. It's lookin like the previous owner of this A2 was in fact a caveman.
Well I fixed the problem the following day thanks to the 5-piece extractor kit I picked up at Sears. I'm suuuuuuuper relieved there were no small pieces that broke off into the cylinder hole!
See attached photos.
91whitecivic, I did a similar setup to yours but sans the welding, thanks for the info tho!
Portflow/Tom? thanks for offering your EZ-out! I'll mention the Copaslip to my friend for his new spark plugs.
How are ya??
