m104.994 tick when warm
 

Before I junk my engine because of aluminum flakes in oil,and tick when warm.Why would it not tick when cold?

Thermal expansion?

when's the last time you changed the oil? could be getting thin.

0 miles on fresh oil. Ticked after 10 minutes

What grade of oil do you use?

Now you are aware that the check valve in the oil filter housing could be bad? That may be your problem of the ticking?

Also, the cam may have worn one of the adjuster or both (Cam and Adjuster).
When cold the metal and valve play is to specification (no ticking, everything is tighter).
The Aluminium flakes may indicate a partial loss of lubrication in certain valve train areas.
After warming up, as mentioned before by Stretch, the metal parts are warmed up (hot), of course, and thereby expand in size (already, considered by the Design Engineer). Depending on the metal and it's properties, this may not be at the same rate. The valve play might get larger (unintended) and you'll get a ticking sound. A mechanical stethoscope might help in finding the one in question. If it is in the Valve train, removing the Valve cover and inspecting the individual valve springs and Cam Lobes, will show marks, if wear is the culprit.

Don't think that your brand new oil is changing viscosity that much.
The key is to find out why the wear occurred in the first place.
If so, then there might be a restriction in lubrication, a restriction in one of the oil bores, for example.

Like always, these are just my guesses.

Did the Oil pressure Gauge indicate a lower pressure as in the past or does it seem to be the same?

I've already bought engine can I sell the old one?

Have u pulled out the old out? Bayhas on the benzworld site he has a SL500, and few W140's with 104's in them. He is smart engine man...

The check valve in the oil filter assembly are known to fail, and they exhibit the ticking symptom on the 104 engine..
