Hello every one. I just got my 93 sc300 about a month ago. 218k running strong. I noticed a hiccup the other morning on start. So its time to give her the old tune up. im doing spark plugs at the moment, im down to cylinder 1 and the plug is seized in. I cant get it to budge with a ratchet and socket. Im scared im going to break somthing if i use a cheater bar. The engine is mildly warm, so im going to wait till she cools and try again. Any pointers on how to get this plug out?

 

Soak it with PB or another penetrating oil and let it sit over night and try again tomorrow

 

Your best bet is to break it loose when it's still hot. You you end up breaking it, there is a special thread repair kit for spark plug. It works the same way as helic coil and it is a little expensive$$$

 

I let some WD sit around it over night and it broke loose the next morning. Thannks a lot. You saved my head.
