Last week I tore down the Renesis engine I bought from Rupert.

     It was amazingly easy, apart from the front end bolt.

     As far as I can tell is the engine in a good condition.
     I have no infos about the engine, but I think it is a very low time
     engine.

     Next step is to clean and inspect all parts and finally do the
     modifications.

     Is the brown varnish around the spark plugs something to be
     concerned about?

     Best regards
     Thomas

     The brown varnish is a common sight. I have seen better rotor
housings.
     The rust in the engine is also a bit strange.

     Paul Lamar ...No rotor no motor.

     Thomas,

     Do you any pictures of the inside (wear) surface of the rotor
     housing, near the intake ports?

     Regards,

     Gordon.

BTW We have no idea how many hours this engine had on it or how much apex
seal
oil it was fed. I think I will start to add .5 ounces of 2 cycle oil per
gallon to
my RX8 to supplement the metering pump amount:) I think the brown varnish
deposits are typical
for a rotary engine burning motor oil out of the crankcase.

Here are some pictures of the rotor housings near the intake ports.
There is some oil on the wear surface because I havent cleaned it yet.

Paul, the only rust I found was in the water jacket.
Is that what you have meant?

kind regards
Thomas


Yes on the rust. If antifreeze was used there should be no rust in the water jacket.
Also the trochoid wear surface should come out shiny. I wonder what they were testing
these engines for? Perhaps limiting the apex seal oil to a very low
values. Perhaps testing different kinds of motor oils? The housing are usable of
course but they look a bit strange for such a new engine. I think if two cycle oil is
used for the apex seals lubrication you won't see those brown deposits on the wear
surface.
