renewed as individual parts.
NOTE: The parts of the cylinder head must not be reworked.

Both cylinder head parts have been matched to each other during production. Two guide sleeves position the cylinder head
parts exactly.

The upper part of the cylinder head is bolted to the lower part of the cylinder head and sealed as follows:

using silicon sealer (seals the outer area),
using a ready-made gasket (seals the swirl ducts and the guides for the fuel injectors).

The upper halves of the camshaft mountings are incorporated into the upper part of the cylinder head. The camshafts run
directly in the aluminium.

The camshafts are made from cast iron. The intake camshaft drives the vacuum pump at the rearward end. The exhaust
camshaft drives the fuel pump at the rearward end. An O-ring provides the seal in each case.

The lower part of the cylinder head is bolted to the cylinder block with a total of 10 bolts. The old cylinder head bolts may not
be reused during servicing.
