Procharger Oil Problem
 

My procharger oil is turning BLACK, this is on a self contained unit

M3SC, only 20 hours on it since a complete rebuild by ATI,



I changed the oil after engine break in , then every 5 hrs after that, gets black after first use

ATI reccomends to change it after 100 hrs :(, oil is very black, some very fine stuff on the drain plug but nothing to be concerned about.



Does anybody use anything besides Procharger oil ???



tech said to flush it with motor oil by filling it and starting it

several times, but do not run it under boost, just idle.

Fixx
 

i wouldn't think you should see anything on the plug,maybe you may have a defective bearing,i would send it back before it self destructs ..is the belt too tight?

have the same unit, mine does not do it...seems bearing is going....call them

I would definately get them to look at it ....what did a rebuild include? If you dont mind about how much was it? ............m

EDIT
pulled the belt off and the bearing on the input shaft is fine, impeller bearing is sloppy
time for a return trip to ATI :(

29 hrs on the boat since a complete blower rebuild..... this SUX

Hopefully I can get it back for our labor day trip

bad ..... but at least you found it before a major blow up .....
