Spark Plug Blow Out


Recommended Posts

Posted

Hey all long time no post. I had the Z34 in storage for a while and I finally returned it to the road last Friday. Well today it decides it wants to blow the rear middle pug out of the head. Any suggestions for repair other then head replacement? I just don't have the cash atm..

find another head at a JY? either that, or see if you cant get it retapped. Im sure it's a pain to get to, but getting it retapped may be a lot easier and cheaper

You could do a heilicoil (sp?)

 

I would take a used spark plug and thread it in and out a few times just to chase the threads personally, followed by a new plug if the hole seems ok.

 

could the plug have not been tightened and worked it's way loose?

Ok I did a helicoil kit on it.. Car now runs like ass but runs. I'm thinking bad spark plug gap. I guess I'll lok at it again in a day or so.
