Normal at cold start and after sitting. The Amsoil with rust inhibitor is Interceptor. Been there with rod bearing corrosion with Dominator on doos, even tho I did fog in off season. Dominator is a great high temp oil, but has the shortcoming mentioned by turbolover - right on. Poo Gold and Extreme are very good oils. Others include Redline, and Legend, which is a dino oil with a low pour point. I've seen least VES buildup now with Extreme. Nothing is magical. The Ski-Doo duckbill oil caps are a direct fit replacement, used to cost about $15US, and will not leak on a rollover. Teth-Air is righton re: potential oil starvation on a Pro 800. The Poo caps are garbage, and stupid on a Pro. Drilling does work, but they will leak if rolled over on a stuck, right above the belt. The oil pump setting below the throttle bodies on this motor should be turned up from the stock setting, if it's not already. This really helps eliminate oil starvation, along with varying throttle with the thumb on the trail. If you're changing the pump setting yourself for the first time, research it well to avoid issues or screwing up the TPS by turning the wrong screw. Don't jump in with a screwdriver until you absolutely sure what you're doing. Someone experienced doing this can show you the easiest way to both check and change the setting with some common hand tools and technique. Lots of info on SW about this, but some of it will appear confusing or incomplete.
If you want more to do - setting the primary belt and track deflection, and belt side clearance, with this motor/chassis helps. Belt and track deflection is very easy. Specialized tools and some knowledge needed for belt side clearance. Fuel filter is expensive, really not that hard to change, but effective for improving running quality. I've changed fuel filters on multiple pros for guys who got the throttle stab stumble - gone. Plug caps need to be tight and clean. VES valves clean. Skid greased routinely - no brass bushings in the Pro. Clean clutches, new springs and belt, and checking weight bushings for wear if it hasn't been done. Clutch alignment check is always good. Clean and fill chaincase lube. Check the throttle freeplay, set to spec (credit card width) to avoid throttle safety switch - TSS - issues. Trying to help if you're not aware, already, and not scare or discourage you - these are proven sleds and common maintenance items to get the most out of it. Only really special tools needed are for the clutches. A bud with Poo experience and clutch tools will set it up for you, too. Good luck! That's the best year Pro RMK made.
