whats this chunk of iron?

[loki2043]

so when i was putting the main caps back on i tapped em in lightly and this little chunk of iron fell from god knows where on the floor. it looks like half of a rat poison pellet that was mangled on one end... i can get pictures if needed....

anybody got any ideas? im down to the bare block with the freeze plugs yanked already so im thinking it might have fallen out of there??? i couldnt see any defects.

Post pics.

Probably crank key.
Pics are good though.

Probably a leftover piece of the casting inside the block coolant passages. There is all sorts of crap in there on most 7m's.

I suspect one of the pins that is used to get the head in the right position... they are usually pretty mangled on one side after getting pounded out.

There's two of them, one at the front of the block and one at the back. The head gasket and head go over them.

ooh, yes... Good thinking Dave.
I forgot they were solid, and pill shaped.

 

[JustAnotherVictim]

Good call grim, I didn't even think those came out. lol

 

[jdub]

Yeah...good call. Might want to check the block/head deck to be sure the other half is not still in the hole

no thats not it..those are intact. its the same exact size as a rat poison pellet. only half of it.. i auctually thought it WAS a rat poison pellet until i threw it out of my way and it made an interesting noise when it hit the floor... i then found out it wasnt! lol pics will be up tonight when i get home from work. what sucks is the block is at the machine shop right now so i cant really check anything. i hope its nothing serious.

 

[loki2043]

okay so after checking the net for pictures i guess there are different sizes in poison! so scratch that idea! pics up later....

Possibly the pivot pin for the timing belt tensioner. I had mine fall out once when I was working on it.

Hmm. Nothing that belongs in any motor if you ask me.

Not a pin to position the head, not a crank 'key'. Pitch it.

 

[loki2043]

well that's what I figured but I swear it fell out of the engine... we already had the freeze plugs out so maybe old junk stuck in there?

 

[johnathan1]

Are both of the dowels in the block? It kinda looks like one of those?

 

[bigaaron]

It's a piece of the casting, I was right!

 

[mattjk]

Oh, that is just a picture from a crappy camera. :biglaugh:

Btw, gotta agree with Aaron.

 

[loki2043]

casting?? what ya mean? is it important?
btw those are pics from my PPC 6700 phone. not too bad for 1.3MP.

Shine a light in the coolant passages looking down at the deck, there are stalactite looking things around the cylinder walls.

 

[loki2043]

well.. ill have to check it when its back from the machine shop. its getting hot tanked while its there also. dunno what ill find in it now...
