Aluminum pieces on a Spark Plug

[ACAMACIAN]

What could this be? I tried to ask this in another post with no response. I apoligize for asking in a new post, but I am not sure what to expect from my mechanic. I would like a little info into what it could be before he tells me what he thinks it is. Where can this pieces be coming from??

He says it still has good compression though, I should of mentioned that maybe. Could it still be that bad!!!

The question is where did it come from? Pull the cylinder head and inspect the head and the piston. It came from somewhere. If it was the head, you could get lucky and only have that. However, you MUST find the cause of the transfer. If the material is from the top land of the piston, you've bought yourself an overhaul/replacement.

I've put two outboards back on the water with head material tranfered to a plug. One was overheated only briefly and I don't know what caused the other one. Both engines have ran afterwards and continued to run for years after that. 9 years to be exact before the 1st one died of a failed water impellor and overheated BIG time. The other is still ticking in Canada.

I've also seen some that couldn't be saved. Either way, it's an ugly sight.

aluminum on a spark plug means the plug met the piston and that the were intimate if it isnt blown yet it will be soon

I was told by a friend it could be a reed valve or fuel injector is that possible or just wishful thinking ?
