Hi I got a 2010 polaris ranger 800 xp. Recently purchased and started to go through the machine doing a full service. starts hard doesn't idle well (has new fuel pump) correct pressure ,cleaned the mass air flow sensor ,had black oily film on it
Compression test shows 165psi in both cylinders uses a small amount of oil like 8-10 ounces in 40 hours of hard use , puffs a little upon start up. top end has wicked rattle/ tick. I'd say it's equivalent to a 7.3 powerstroke on the obnoxious level
I assume it got hot at some point due to low fuel pressure (lean) exhaust manifold was cracked Machine runs great if u start it with a little throttle then it will stay running and has a lot of power. The top end gets quiet at high rpms. If anyone has any ideas any help greatly appreciated Thank you
