How to Permanently Solve the Oil Burning Issue in the EA888 Gen 2?
2 Answers
It is impossible to permanently solve the oil burning issue in the EA888 Gen 2. Here is some knowledge about the EA888: 1. Introduction: The "Volkswagen EA888 engine" is a newly designed engine by Volkswagen, integrating advanced technologies such as direct injection, turbocharging, and variable valve timing, achieving a balance between power and fuel economy. 2. Solution: Replace the piston rings. Poor sealing of the piston rings is the main culprit behind the EA888's oil burning issue. Poor sealing allows oil to enter the combustion chamber, where it burns along with the gasoline, leading to a gradual decrease in oil level.
I have a lot to say about the EA888 Gen 2 oil burning issue. My old Tiguan had this exact problem. A complete engine overhaul is the only real fix! Last year, I spent 8,000 RMB on a thorough repair: First, replaced the piston rings with improved wave-style ones (the factory design flaw caused poor oil scraping). Second, swapped in a Gen 3 EA888 oil separator (the original one was like a sieve). Third, replaced all valve stem seals with high-temperature resistant fluororubber ones. After the repair, I've driven 20,000 km, and the oil dipstick still shows a perfect middle level. A reminder: don't forget to check the transmission seals. A clogged crankcase ventilation valve can worsen oil burning. This money is truly worth spending—rebuilding the engine is far more economical than buying a new car.
