I just transplanted a 3.0 OM603 in a 94 W140 car. Engine has not been started for around 5 years, has 112K miles on it, runs and sounds good.

The return lines were rotted and fuel pooled around the injectors and I noticed air bubbles around all of the injectors' bases.

What needs to be done in order to fix. Thanks in advance.
