Disadvantages of the GM LE5 engine
- A known problem with this power unit is the short-lived timing chain.
- When replacing chains, update the balancer chain tensioner (not included in the timing kit).
- Ignoring the rattling chains leads to rapid wear of the stars of the phase regulators.
- On a run of more than 100,000 km, lubricant consumption is often found due to the occurrence of rings.
- Also here, the crankcase ventilation is often clogged and the exhaust manifold is cracking.
