Tech Corner / Blown Head Gasket?????
March 25, 2006, 07:32:44 PM
Got another Sportsman 500 from my dad's place.  Hasn't been run for almost 3 yrs.  It cranked within 3 minutes of trying to start it.  But...

There is white smoke coming from what appears to be the exhaust manifold area.  I also found some coolant on the ground under the front end of the engine.  Doesn't this mean that the head gasket has failed and coolant is leaking into the cylinder??

Any help or advice would be appreciated.  I have rebuilt Polaris motors before so rebuilding the top end would be an easy weekend project.

Tech Corner / Exhaust help
December 08, 2005, 02:52:05 PM
I have been rebuilding one of our POL SP500s that had been sitting in my dad's barn in TX.  Replaced basically entire elec system, rpms are too high but runs ok.  Now at the silencer connection and at the manifold connection the exhaust is smoking.  Is this a bad exhaust pipe or is the silencer shot (clogged)????????
