Matt repairs a water soaked Onan generator; Yes he was able to make this run

 It is very fun and educational to go through with repairs of Matt, making almost junk equipment run agian  This time it was a water soaked Onan diesel generator.   It was really water soaked:   the air intake filter was filled water; and so with its oil, its fuel tank, its fuel, and fuel lines.  Even its internals.

Matt showed us methodically and patiently:

1.  How to power up batteries and the starter;

2.   Removal of water from the air intake

3.  Freeing the engine from water lock (opening exchaust valve vie the hims on the tappet to open the exhaust valve on compression stroke to vomit out water in the cylinder.

4  Removal of water from fuel tank and lines.   (Cranking up the engine after cracking up the bolts of the fuel lines

5.  Changing oil and replacing the filters

6.  Getting the engine to compress the fuel for ignition

And then success

VERY INFORMATIVE

Turbo failures can cause engine failures which can be caused by bad filters.

 Engine failures especially low power can be caused by turbo charger failures which can be caused by:

       1.  Non delivery of oil or coolant to the turbo;

       2.  Old oil non functioning oil filter

       3.  Carbon deposit on the turbo shaft due to sudden turning off of engine after a long drive (thus

            burning oil)


Be sure you take good care of turbo if your vehicle has one






Black smoke after replacing turbos and injector

 It could be due to the intercooler.   Signs of defective intercooler:   black soot and oil at the underside from the leak.
