1998 discovery. had exhaust gas coming through expansion tank and suspected HGF. Took head of and saw white milky blobs on top of two pistons, also a hard brown substance that looks like it ran down the bore about 2 inches, any idea what this is or is it part of the HGF. A bit of corrosion on the head itself, hope its still useable.
