OK, not directly a 914 problem; Thankfully, my 914 is running fine. (IMG:style_emoticons/default/biggrin.gif)
Can't say the same for my 2005 F150 that decided to fire a spark plug from the #3 cylinder hole. (IMG:style_emoticons/default/mad.gif) Heard a ticking sound that progressively became louder then, kaaPow!. Fired that sucker right out of the threads. Broke the coil and split the spark plug. WOW. I would like to say that this was unique, but the same thing happened to another cylinder about a year ago. Helicoil solved it. This is getting stupid. Anyone else have this type of problem? Wonder if Ford had a recall regarding this. Only 85K on the engine...Fix and sell? (IMG:style_emoticons/default/smash.gif) Found On Road Dead? (IMG:style_emoticons/default/screwy.gif) |

I read that the problem is actually not enough threads for the spark plug to screw into. Supposedtly the defective head only covers half the threads, so over time the spark plug works its way out.

Hey Steve, If a Helicoil won't satisfy you as a good fix, you could look into the spark plug inserts used in VW heads....evidently, they found the problem decades ago. BTW: I'm completely sympathetic to this problem as I've experience some thread problems on the ALU heads on the Chevy engine in my 914. Best, Terry |
