Q: Why is my V2403 engine experiencing high oil consumption despite new rings?
A: This often occurs if the cylinder wall glaze wasn't removed or if the 1A091-21050 rings weren't seated correctly. Ensure the bore is exactly 87mm and use OEM standard replacements to maintain oil film integrity.
Q: Can I use 1G780-21113 in a non-turbo V2403 engine?
A: While the bore is the same, piston crown designs vary between DI (Direct Injection) and IDI models. Always verify your specific 1G series part number to ensure proper combustion bowl geometry.
