Your bypass valve is a sealed unit..
The more likely issue will be one of these:
*
OM603.960 and .961 Plastic fuel lines, injection pump
*
OM601, 602, 603 Lift pump Repair kit
*
OM603.970 Injection pump output Re-seal
*
6010700282 Fuel Thermostat
*
Diesel fuel thermostat repair kit, huge application list
