Why is my Big block 396 smoking out passenger side tailpipe?

If your Big Block 396 is smoking out the passenger side tailpipe, it could indicate oil entering the combustion chamber, possibly due to worn valve guides, seals, or piston rings. Another possibility could be a coolant leak, suggesting a head gasket issue or a cracked cylinder head. It's important to conduct a thorough inspection to identify the exact cause and address it promptly to prevent further engine damage. Consulting a mechanic would be advisable for a definitive diagnosis.
