what you guys suggest as the easiest fix for messed up spark plug hole threads for EA81? just #4 hole is messed up.

helicoil?

retap?

replace head?

other?

They have spark plug chasers. It's just like a tap, but designed to fit in a spark plug wrench.

You should be able to get it from any auto parts store.

good to know. thanks!

When doing it make sure to coat that thread cleaner with grease so that any metal shaving stick to it instead of getting dropped into the cylinder.

Assure to put anti-seze on your plug threads each time they are removed. Cast iron heads were much more forgiving then the allum. heads. You can usually find little one use packets in the auto store or by the can.

 

I put some on the plug threads and a light coat on the buggerd threads in the head and slowly worked each plug in, backed off and back in etc.. and became usable just by doing that. Anti-seze is a must on the plugs.

 

 

a previous post someone suggested:

 

..after all that is done and threads still messed up, put some thread lock (epoxy, expando etc..) on the threads, drive it in till it seats, let it cure and run it for a couple years then deal with it another day.

i am now at the "another day" phase.....

great advice, common sense stuff all 'round, but it never can be repeated enough. thanks guys~!

That is cool! I found one of those on the trail last year and kept it because I thought it was neat, but I had no idea what it was. Now I know! (and knowing is half the battle...)

What size and pitch are the spark plugs in a EA82T?

 

I need to redo one of mine and this would be perfect.

I did that to an EA82T. My chaser tool was magnetic, but I greased it anyhow. That lasted thru 4 plug changes, then I had to do a threaded insert.

 

Helicoils are for the birds! More often than not I end up pulling the coil back out with the bolt. If you can get to it, use a threaded insert.

Spark plugs are a standard thread and pitch for spark plugs.

Yeah, a megnetic chaser isn't going to help with Aluminum, it's not magnetic.
