Stuck Sparkplug.

[KEhendo]

ok, so i finally got some money and decided to service my crown with my new took kit. 5 of my 6 spark plugs came out fine but the number 5 just wont budge. the metal rod in the end of the plug tube started bending so i called a mate to come and use his 'stronger' plug tube. the plug ended up rounding his plug tube. i then called another mate to borrow his proper sparkplug socket. when he got to my house we found that it was too thick to fit in the gap between the plug and head. :lolcry:

 

does anyone have any ideas? i'm thinking of taking it down the the local mechanic to see if they can get it out for me.

 

cheers, hendo.

 

ps. i have drowned it in WD-40 and CRC.

Aluminium or cast iron head? I'm guessing aluminium?

 

Thermal expansion on Aluminium is higher than steel, I would give it a shot when the motors warm, that might be just enough to release it's stranglehold.

 

Emphasis on might.

i think it alloy, it's a 4M out of an MS65.

 

i'll go warm it up now. :lolcry:

You mean the spark plug socket won't fit in the hole around the plug?

 

If so this is also a problem with 13b turbo motors. The casting around the plug won't allow the use of a normal socket. You can buy proper mazda one for doing this but they do cost a fortune, most rotary owners/workshop just get a normal plug socket machined down until it fits in.

So.... if you've got any mates who are right into 13bt's ask them if they have one, alternatively you might be able to borrow one from a rotary workshop. Because they're machined they are slightly weaker so if you can borrow one don't be suprised if the say "you break it, you bought it". :lolcry:

we deal with seized glow plugs, i just crc the living hell outta them and unscrew it asmuch as you can (untill you think its gonna break it) then screw in and out 5 times and heyyy presto :lolcry:

yeh, this is the problem. the cars just warming up now so i'll try philbey's way then if that doesn't work i'm off to find a rotary workshop.

Just noticed your in melbourne, there's a few about there. Maybe just drive the car there and see if you can use it in the parking lot. :lolcry:

ok, took it for a drive down the street to try and warm it up. got home, still wouldn't move. decided to call up the local mechanic to see if he could help. wasn't keen on driving the car very far with no plates. turns out one of the mechanics likes rotaries and has an rx4. he had the actual mazda bit and swapped all my plugs for me, free of charge.

 

thanks to all for your input. thats one more thing off my list.

 

cheers. :lolcry:
