## First Two Engines Showed Severe Damage
Eric's first two torn-down Toyota V35A V6 engines had clear signs of internal damage from debris in the oiling system.
## Third Engine Shows Early Cooling System Issues
This engine has crusty water pump and coolant intrusion at gaskets, but no catastrophic failure yet.
## Warped Head and Uneven Bearing Wear
Removing heads revealed a warped cylinder head and uneven wear on thrust bearings, but clean crankshaft.
## No Clear Cause for Engine Failures
Despite signs of internal wear, no smoking gun found; engine came from 2025 model with no catastrophic failure.
## Key takeaway

Toyota's V35A V6 engine failures may stem from internal wear, not overheating, as a third engine shows no catastrophic damage but early signs of cooling system issues.
