heres my prob i just put my eng back to gether full rebuild new gaskets,main and rod bearings, ARP studs,and hks MHG. when we did the first start up after a few minuts idleing it was milk shaked so we pulled it back apart and MHG was perfict...but cylinder #6 had some water in it and no carbon on the piston like the rest, there is some pitting and a wear ring near the BDC in the cylinder wall and where thinking it might be craked so im geting it checked asap...but i know i didnt get the head or block resurfaced to begin with, but will now any way...I want to reuse the MHG since it was only ran for a cpl miniuts do i need to still take off the vitron ( is it the black coating on the MHG )
