Metal shavings on spark plug
|
I will say this; metal shavings dont belong in the cylinder. If I had metal shavings in my 383 I would say it time for the 396 build up.

Agree with Pete.... Metal in the cylinders means major problem. Because what's failing will most likely destroy your piston rings and cylinder walls next if what is failing doesn't break first. Sounds like a tear down rebuild time to me!

Only "good" scenario is that the spark plug was cross threaded when installed and the shavings fell into the head. Better chance of a piston problem though. |

Ill have see what a compression test reveals |

not at all
but ther are some people over there that I have met and would like thier input as well. |
Monte....Jon said it all. If the plug isn't crossthreaded, it's time for exploratory surgery....and I don't think you're gonna like what you find. The metal shavings are either coming from the piston, cylinder wall, or head. It's possible you have an oil gallery plugged and that the valve guide is starving for oil....thus wearing it down and depositing the remnants on your plug. That's the best case scenario.
I don't think I have to tell you what the worst case scenario is. Sorry to be the harbinger of doom, but..... Let us know what you find out. :cert: |

The minimum would be to do a compression check and have your oil analyzed. Blackstone Labs Blackstone sends out free kits for you to send a sample of your oil and you get the results back. |

At minimum I'd agree with Friz and say pull the head and see what you find. With that many shavings in a single cylinder it will probably be pretty evident. Have you looked in your oil to see if you are getting obvious shavings out of the bottom end as well? |

Gotta agree with Taurus and Friz...Looks like piston damage from running lean...
|
So would a compression test be worth anything?
|
Wouldn't hurt but the results could be misleadeing...You said there is only 200 hundred miles on the new motor right?

Best to pull the heads and have a look or use a borescope.... |

could be valve train bits coming down the valve guide...does it burn a lot of oil? |
