Close Call - Plug Backed Out

[baron1701]

I Have Heard Of Plugs Getting Stripped, But Backing Out?

About A 2 Months Ago I Had A Noise Creep Up In The Valve Area That I Thought May Be Serious. With 170.000 I Figured It Was About Time For Something I Couldnt Fix. I Changed The Oil About 3 Times Since Figuring I Ran Low A Little Two Long (typical Crank Case Seal Leak) And Thought It Was Better.

Finally I Was Doing A Whole Bunch Of Stuff With The Car On The Lift ( Oil Change, Rad Fluid, Level Sensor ) When I Noticed A New Level Of Noise. The Engine Was Making A Noise Like An Exhaust Flapper. One Of My Rear Plugs Was Practically Falling Out. The Boot For The Plug Was Flaping Around Under Exhaust Pressure Creeping Around The Plug. I Guess Being Afraid To Strip An Aluminum Block Can Have Its Disadvantages. Now My Power And Economy Is Back And I Have A Noiseless Engine Again.
