Low or No Oil Pressure/High Oil Consumption

Low or No Oil Pressure, Oil Contamination - Can-Am ATVs

Check Oil Level and Search for Leakage
- Crankcase is leaking due to damage. Rebuild engine with new crankcase and gasket parts. Use recommended oil.
- Crankcase is leaking due to loose screws. Retighten screws with recommended torque.
- Sealing rings, O-rings, and/or gaskets are brittle, hard, or damaged. Replace damaged parts.
- Piston rings worn out (blue colored engine exhaust emission). Replace piston rings.
- Piston rings are broken (low compression). Replace piston rings.
- Valve stem seal damaged and/or sealing lip is hard and/or brittle. Replace all valve stem seals.
Check Oil Filter for Contamination
- Oil filter clogged. Replace oil and oil filter at the same time. Use recommended oil.
Check Oil Drain Plug
- Plug is loose and/or gasket ring is missing. Retighten the plug and/or place gasket ring.
Check Leak Indicator Hole if Oil Leaks
- Oil leaking from leak indicator hole means a damaged oil seal on water pump shaft. Replace oil seal.
Check Oil Pressure Switch Function
- Oil pressure switch damaged. Replace oil pressure switch.
Check Oil Orifice(s) on the Oil Pump Suction Side
- Oil orifice{s) is (are) clogged. Clean from contamination. Replace oil and oil filter if necessary.
Check Oil Pump Function
- Oil pump rotor is out of wear limit. Replace oil pump.
- Oil pump seized due to oil leakage and/or air inclusion. Replace oil pump.
- Gears driving oil pump are broken or otherwise damaged. Replace gears.
- Incorrect oil being used. Use recommended oil.
Check Oil Pressure Regulator Valve (Spring) Function
- Valve spring damaged (valve always open). Replace spring.
- Valve piston is worn or broken. Replace valve piston.
- Valve piston stays open due to contamination. Clean or repair valve piston.
Check Plain Bearings in Crankcase for Heavy Wear
- Plain bearings out of specification (increased clearance). Replace plain bearings.
Check Engine Oil Strainer in Crankcase
- Oil strainer is clogged due to contamination. Clean or replace strainer and diagnose causes. Replace possible damaged parts.

Oil Contamination (White Appearance)

Check Leak Indicator Hole if Coolant and Oil Leaks
- Leakage of oil/coolant mixture from indicator bore means damaged water pump seal ring and rotary seal. Replace sealing ring, rotary seal and change oil, oil filter and/or coolant.
Check Cylinder Head and/or Cylinder Base Gasket
- Gasket damaged or leaking. Retighten cylinder head with recommended torque and/or replace gasket.
Check Tightening Torque of Cylinder Head Screws
- Screws not properly tightened. Retighten screws to recommended torque and replace oil.
Check Oil for Particles
- Oil contamination due to metal or plastic particles. Replace possibly damaged part(s) including oil and oil filter. Use recommended oil.
