Warning, aluminium cylinder block! The crankshaft and pistons

must not be removed. Just loosening the main bearing caps

will cause deformation of the cylinder block bearing pedestals.

This deformation will cause a reduction of the bearing clear‐

ance. Even if the bearing shells are not renewed bearing

damage could occur due to a different bearing clearance. If the

bearing cap bolts are loosened, the cylinder block must be re‐

placed complete with the crankshaft and pistons. Measuring

the main bearing clearance is not possible with normal work‐

shop equipment.

Note

♦

Secure engine to engine and gearbox support -VAS 6095- to carry out repairs.

♦

Engine must not be set down on oil sump, as this will damage the liquid gasket between the upper and lower

sump.

♦

Finding metal shavings or a large quantity of small metal particles during engine repair could indicate that

the crankshaft bearings or conrod bearings are damaged. To prevent this from causing further damage,

perform the following repairs:

♦

Thoroughly clean oil passages,

♦

Renew oil return valve,

♦

Renew oil spray jets,

♦

Renew oil cooler,

♦

Renew oil filter.
