Sprinter 906 OM651.955 non gen oil filter found 3 old filter parts and various shit in filter customer just purchased had servicing done at a Branded Service Center in Newcastle suburbs

.  Same  Sprinter 906 316cdi went to old mates with a oil leak, yes we fixed it... 3 months later still leaking, advised them to go back and get old mate to fix it. Still leaking 9+ months later fed up with excuses.

 No one is perfect, but they wipe hands of it.

Customer has issues later with erratic fault codes low voltages etc.

Diagnose Alternator is likely the culprit, We supply and fit a OEM Alternator but notice a water pump leak and huge oil leak.(not always leaking though)

We pull a bit of shit off, looks like a oil sensor leak, but after replacing still leaking, Never had a oil leak like this before. It would leak at start up but once turned off and restarted it would stop leaking.

Unfortunately it had to put off the road as serious damage was likely if it kept losing this amount oil. Ended up letting it sit a whole day and stripped the engine bay clear of all A/C, power steering pumps and other accessories. A clearer picture now of where this leak was. run it for 2 minutes or so with no belts etc, found the area involved and started stripping back to the block.

Looks like old mate decided that he could squeeze a tube of sillastic in the oil galleries and miracles will occur, they skipped O-ring Training day,  that flapping sillastic shown in picture was the tap turning on and off  it would sometimes seal and other times be the path of least resistance.

Formed in place gasket material is the current trend with manufactures, but should be used wisely, with caution near oil gallerys.

Not sure if they put new o-rings in or just did the sillasitc trick. Probably would last 3 months.

Unlike some situations where a dob of FIPG formed in place gasket material is clamped between 2 solid surfaces and held in place by bolts, this situation has a o-ring located in a groove on a  plastic tube coming from the oil filter housing that inserts into the hollow section of the alloy cooler and steel section of engine block, thus 3 different materials needs a flexible seal.

This job was done at least 2 times but who really knows, old mates invoices were vague, poor job descriptions, lacking any real evidence of the work carried out.

All up this poor customer was out of pocket close to $2500 with the previous workshop,

We repaired the leak using genuine Mercedes-Benz parts, replaced the oil filter housing/oil cooler assembly as a precaution.

The other workshop's invoice was not itemised, Service and repair oil leak was the description, lumped in parts costs. We did approch the worksop as they didn't refit the ducting for air cleaner, air con, engine covers and cowlings, excuse was the customer was to return and verify the leak had stopped, they didnt return so we threw out the parts as they were lying around.
