HSV W427: low oil pump pressure due to sticking oil pressure relief valve
In May 2013, General Motors issued Technical Service Bulletin PIP4158F for 2007-13 model year vehicles that had the following engines –
- L76: 6.0-litre V8 with AFM hardware;
- L77: 6.0-litre V8 with AFM hardware and flex-fuel capability;
- LS2: 6.0-litre V8 for HSV models;
- LS3: 6.2-litre V8 for HSV and, subsequently, Holden models; and,
- LS7: 7.0-litre V8 for the Chevrolet Corvette and HSV W427.
Due to the oil pump pressure relief valve sticking, these engines may experience low oil pressure, no oil pressure and/or engine noise. In some cases, these symptoms would occur intermittently if the valve freed up when the engine cooled down.
If GM’s Service Information (SI) diagnosis isolated low mechanical oil pressure at the oil filter housing and oil pressure sensor, the oil pump was to be replaced, the oil cooler lines flushed (if fitted), the inside of the oil pan cleaned, the oil changed and the oil filter replaced.
HSV W427 with LS7 V8 engine: belt squeak noise and/or crankshaft balancer wobble
In January 2012, General Motors issued Technical Service Bulletin PIP4750D for 2008-12 model year vehicles which had the following V8 engines –
- L76: 6.0-litre V8 with AFM hardware (introduced in January 2009 for Holden VE vehicles);
- L77: 6.0-litre V8 with AFM hardware and flex-fuel capability (introduced in September 2010 for Holden VE Series II vehicles);
- LS3: 6.2-litre V8 (introduced in April 2008 for the HSV E-Series); and,
- LS7: 7.0-litre V8 (used in the Chevrolet Corvette and HSV W427).
Since the bulletin identified the Pontiac G8 and Chevrolet Caprice, both of which were produced by Holden, this bulletin is considered applicable to Holden’s VE and WM ranges and HSV’s E-Series.
According to the bulletin, these engines may:
- Emit a belt squeak noise. If this occurred, the drive belt was to be replaced; and/or,
- Exhibit a crankshaft balancer that appeared to be out of balance (i.e. appeared to wobble while the engine was running). The technical bulletin described a procedure to measure balancer run-out and, if greater than 4 mm, the crankshaft balancer was to be replaced.
HSV W427: rattling noise from front suspension due to ball joint corrosion
In August 2015, General Motors initiated for Customer Service Campaign 10058796-6065 for 2008-09 model year Pontiac G8 vehicles (which were manufactured by Holden); as such, Holden’s VE and HSV’s E-Series range are also considered susceptible to this problem. In these vehicles, the boots on the front lower control arms could become rigid in cold weather – this could allow water to enter the joint and corrode the surface of the ball joint. If this occurred, a loud metallic rattling noise may be heard from the front suspension when the vehicle is driven on rough road surfaces. As part of General Motors’ Customer Service Campaign, the warranty was extended to ten years or 120,000 miles (193,000 kilometres), whichever came first, for this condition.
Problems and faults: HSV E-Series W427
- The windscreen washer container was susceptible to cracking – this was a common replacement item.
- Water may leak into the front passenger foot well due to drain tubes cracking at the air box.
