is that indentation on the head from the washers?

is that indentation on the head from the washers?

Yes. Up to 1/16" in one.

If you look at the top picture, you can see where the inside of the hole actually broke away. Small chunks of metal were stuck to the washer when it was pulled.

Std thickness 12v. Head was o-ringed.

 

[cummins359]

what was the reason for removal?

 

[imcummin]

Damn and I'm about to switch over to the 625s.

Lost a soft plug in the head. A ton of coolant got in the oil. Bearings and crank were roasted.

 

[duck_04]

probably bad casting, and thats probably the reason the freeze plug let loose

The head came from a member on here. It was supposed to be from an '05 Dodge truck with little hours. The head has "ECHO" stamped in the casting behind the intake plenum plate, near the back of the head. I have never seen this on any other CR head.

 

[The Legend]

[coon smile]

10 thou I believe.

 

[cummins359]

possibility that the head was one of those Ebay specials?
