The one and only EcoGen I installed blew out its
oil in within the first couple hours of running.
It severely damaged the engine. Generac did the
service and ultimately replaced the unit. It had
something to do with the two reservoirs and the hoses.

Wrenches,
I service an off grid home that has an EcoGen
6kW Model 58181 LP gen with a Serial Number of
8301854. It has 1,175 hrs on it during 2-1/2 years of service.
· It appears that the crankcase is
filling with excessive amounts of oil.
· There was a Generac Service Bulletin
in July of 2013 which predates this generators
Serial Number. This bulletin alerted the
possibility of excessive oil in the crankcase
due to "incorrect routing of the pulse pump hoses".
· From the pictures on the service
bulletin (and with the SN being higher) it looks
like the generator in question has properly
routed hoses. See photo attached if you are familiar with this problem.
· There is an extra oil reservoir on
these units. The engine takes 1.7 quarts and the reservoir takes 4.2 Quarts.
· I last changed the oil (and properly
filled both engine and reservoir) at 1,124 hours
· Now at 1,175 hrs the generator runs
very roughly and blows lots of oily smelling
blue/grey smoke. Most of the oil is gone from
the reservoir so it's pretty obvious that the
oil has flooded into the crankcase.
· If the Pulse Pump hoses are routed
correctly and I'd say they are since the SN is
later than the recognized problem AND the fact
this generator ran great for over 1,100 hours
then maybe is the pulse pump itself is bad?
· I wanted to run this by this list
before talking to Generac because I know there
are a number of wrenches whom have experience with the EcoGen.
· Can I simply just drain the oil and
only refill the 1.7 Qts in the engine and run the unit?
Thanks for your time,
