Background:
A new cylinder block was introduced in August 2003. The changes were also included on exchange engines for the above vehicles.
The exchange engines are supplied with oil separator box (Oil Trap) 8692211 and hose 8692217. On the S60/S80/V70 (00-)/V70XC (01-) up to model
year 2001, and on the C70 up to model year 2002, there is a conflict between oil separator box and ETM.
The solution is to remove the oil separator box and hose supplied with the exchange engine & transfer the oil separator box 1271988 and hose 1271654
from the old engine after grinding down the attachment lug in accordance with the service bulletin.
Description
Remove the oil separator box from the old engine.
Cover the openings in the new block so that no grindings enter the engine. Grind down the attachment lug at least A = 5 mm (13/64 inch).
Align the oil separator box on the cylinder block and check that there is a clearance of 1-2 mm between the oil separator box with hose and clamp
installed and the newly ground attachment lug. Install the old oil separator box on the new engine.
