450 rebuild

Postby Jason (IL) » Sun Dec 07, 2014 10:02 am

I tore into my 450 to fix a few minor issues and what I found was a shock. Now that I am this far I guess I will just fix everything and more. Found the valve and valve guide were seized and both were moving through the head. I guess a rebuilt head is in store.

OUCH! Hopefully the bore in the head has not been badly wallowed out by this, but I'm afraid it probably is...

The machine shop can certainly do something about it but it might not be inexpensive.
