I am playing brave today changing plugs on my 94. The back rotor Leading plug is seized, look like they were not properly lubed with anti-seized compound. The porchelain is already broken so the plug must come out.

Beside spraying WD40...what else? I am afraid the threads will come out with the plug

Any suggestion?

 

get that yellow can called lock something? spray and let it soak maybe 30mins.

 

liquid wrench?

 

I've always had good luck with penetrating oil. Give the plug a couple of squirts, tap on the hex part of the plug to try to loosen the plug enough for the oil to get in. Squirt it again, wait 10 minutes, try to remove plug. Repeat till it comes out.

 

yes liquid wrench thats it. let it soak and then try again.

 

got it out...it was so nice to see no threads from the housing.


Thanks all.
