Mercedes Benz 300 SDL head.
The picture above shows the top and bottom
half of a 1988 Mercedes Benz
300E AMG Hammer
6.0L V8 4 valve cylinder head. The "2 piece" heads split
down
the middle horizontally. A pair of
these heads came into the shop
leaking coolant and
after pressure testing it was determined
that they
were leaking at the
seams
between the two
halves. The heads were
disassembled including removing the
valve guides
which was necessary
in order to
facilitate the separating of the two
halves.
The picture on left is the bottom half of
the head showing the top of the ports
& chamber of one
cylinder as seen from inside the water jacket. The hole in the center is the bottom half of
the
spark plug well and the four
holes surrounding it are the valve guide bores. The picture on the
the right is the top
half of the head showing one of the old worn out o-rings that seals the spark
plug wells. All The studs and dowel pins were
removed, the spark plug wells were bead blasted
and the cylinder head halves were hand
lapped and cleaned. For assembly the halves were coated
with sealer, the studs, dowel pins
and new o-rings were reinstalled. The heads were bolted to
torque plates in order to help clamp the halves together.
Later new valve
guides were fitted and
the heads were finished off with a Competition Valve Job and installed on a
modified 400HP 6.6L V8
