Engine Failure Analysis Tips
Guide to Preventing Repeat Engine Failures
Overview
Guide to preventing repeat engine failures
Progression List
Cause
Leading to
- Each damaged engine scenario starts by providing some root cause examples
Effect
Leading to
- The effects of what can occur if root cause is not addressed or the repair is left incomplete listed here
Damage
- End result or damage that can be experienced if root cause of original engine failure is not accurately identified highlighted here
In situations where partial diagnosis suggests engine replacement may be necessary, such as:
- Bearing damage
- Engine noise
- Cylinder misfire
- Loss of compression
- Metal contamination
- Undetermined oil consumption
If the true root cause is not identified (with visual confirmation to the extent of total damage), an over repair or an incomplete repair leading to repeat engine failure may result.
This bulletin targets specific gas engine failure modes and includes a progression list highlighting:
- Cause
- Effect
- Damage
The progression list assists in identifying certain common operational concerns, overlooked contamination scenarios, and incomplete repair possibilities. (see example on left)
Piston Damage
- Pre-ignition
- Excessive Levels of Detonation
- Engine Performance Modifications
- Aftermarket Fuel System Modifications
Misfire from Valve Leakage
- Excessively Lean Conditions
- Excessively High Cylinder Temperatures
- Aftermarket Induction Modifications
Cylinder Wall Scuffing & Scoring
- Catalyst Material Ingestion
Piston and Valve Damage
- Foreign Object Debris
Severe Oil Consumption
- Open Breather Tube Fitting in Place of PCV Valve on 2v Modular V8 & V10
Bent Connecting Rod
- Hydrolock
- Injector Failure
- External Water Ingestion
