Piston slap in Holden Monaro
Answered by Graham Smith · 10 Mar 2011

You'd need to have an experienced mechanic listen to the noise to determine if it's piston slap or not. The LS1 certainly rattled on cold starts due to piston slap, and it used oil, they were the giveaways to a problem with the engine. Yours could have some piston slap, but your description suggests it's not serious, and certainly if the engine isn't oil to any degree I wouldn't be concerned. The noise could also be a worn lifter, that's why you need someone with experience to listen to it.

Used Holden Monaro review: 2001-2002
By Graham Smith · 23 Jan 2009
Holden took everybody by surprise when it unveiled a slinky new coupe concept at the 1998 Sydney International Motor Show. The Commodore-based coupe was a well-kept secret and was the hit of the show.At the time of the unveiling it didn’t have a name, it was simply called the Commodore Coupe, but it wasn’t long before it was being called a new Monaro after Holden’s classic 1960’s coupe.Although there was some resistance to the name inside the company there was no denying public pressure and it was eventually decided to reprise the Monaro badge for the new millennium remake. A modern day classic was born.MODEL WATCHThe Monaro was launched in 2001 and remained true to the concept coupe. There were a few changes, but they were minor and barely noticeable.At the front, apart from a new grille and headlights, there was little to distinguish the Monaro from the Commodore, but rear of the A-pillars it was all new. The roof line was 40 mm lower and sleeker, the B-pillars were moved back to make the doors 150 mm longer, and the rear was shortened by 100 mm.Holden released two versions at launch, the supercharged V6 CV6 and the Gen III V8 CV8. Holden’s idea was that the Monaro would be a sophisticated grand tourer in the European mould and would attract buyers who didn’t necessarily want a thundering V8 under the bonnet.Unfortunately it would prove to be a miscalculation and the 171 kW blown six was an overnight orphan, and quickly dropped from the range as buyers flocked to the CV8.The V8 was the familiar 5.7-litre Gen III all-alloy V8 imported from North America. A pushrod design with two valves per cylinder the Gen III put out 225 kW at 5200 revs and 460 Nm at 4400 revs.Unlike the earlier Holden V8 the Chev unit was a high revver with less punch down low. When revved it would get up and go hard, but with the six-speed manual gearbox it could also be quite economical with a light right foot.There was also a four-speed auto available, which was less exciting, but meant you weren’t constantly shifting gears as you tended to be with the manual.Underneath, the Monaro was familiar Commodore, with MacPherson Strut front suspension and semi-trailing arm independent rear suspension.Brakes were discs all round, and ABS was standard along with traction control.Appropriately for a car at the upper end of the range the Monaro came fully equipped. Leather trim was standard, along with air-conditioning, cruise, 18-inch alloy wheels, trip computer, auto headlights, power seats with memory settings, and premium sound system with 10-stack CD changer.IN THE SHOPThe Monaro suffers the same problems as the mainstream Commodore. Owners report small glitches in power window winders, high mount brake lights coming adrift among the more common problems.The most concerning issue is with the Gen III V8 engine and the well reported piston rattle and oil consumption problems. Some engines suffer from piston rattle, best heard as a light metallic rattling noise when cold, others from high oil consumption, as high as five litres between oil changes, and others have both problems.Holden claims the problems affect around 20 per cent of engines, and claims to have fixed them by rebuilding problem engines with Teflon-coated pistons and reduced piston to bore clearance.Most owners are happy with the fix, while others report that the problem has returned after 30-40,000 km. Some engines have been rebuilt more than once.When considering buying a CV8 take the time to listen for the piston rattle, and ask the owner if the engine has shown any problems or been rebuilt.Once you’ve bought the car keep a close eye on the oil consumption with regular checks. If the engine is consuming oil keep a record of how much oil you add at what odometer readings.Failed supercharger nose bearings are common on the CV6, but changeover blower noses are available.IN A CRASHThe Monaro was fitted with driver, passenger and side airbags for comprehensive all round crash protection. It’s not included in the recent used car safety survey, but the VT/VX Commodore is and that rates significantly better than average for occupant protection, but worse than average in protecting others.OWNERS SAYWolf Haefele fell in love with the Monaro when he saw it at the Sydney International Motor Show. He loved its shape and thought it was the most beautiful coupe ever. He bought his in 2002. He’d only had Japanese vehicles before the Monaro, but was convinced to buy his first Holden after being invited to a Monaro drive day with Peter Brock. The Monaro handled exceptionally well, had plenty of power, but also had the trim and quietness of a luxury car. It has now 16,000 km, and has been very reliable; his only complaint is that the boot hinges eat up the cargo space.LOOK FOR• Head turning looks• Wild hero colours• V8 performance• V8 piston rattles and high oil consumptionTHE BOTTOM LINEStylish coupe with head turning looks, wheel spinning performance, and future classic potential.RATING80/100

Used Holden Monaro review: 2001-2006
By Ewan Kennedy · 29 Apr 2012
A two-door Commodore Coupe in concept was the runaway star of the 1998 Sydney Motor Show. Interestingly, Holden use the name Monaro for this stunning two-door, saying a fresh new model needed a new name, hence the tag of Commodore Coupe. The public strongly disapproved, demanding that the car be called Monaro and, a long three years later the new Monaro finally hit the road in December 2001.The new Monaro shared its wheelbase and much of its drive train with the Commodore sedan. But, obviously, many body panels were unique to the coupe.The body is 100 mm shorter than the sedan’s but two passengers can sit in reasonable comfort in the back seat. Headroom is the governing factor, not legroom. So take a couple of tall passengers for your road test.The interior is more distinctive in its finish than the sedan’s. Even the less expensive Monaro model has leather trim. The front seats have power operation and a smart release mechanism that makes them slide forward automatically to let people into the back.The boot is surprisingly voluminous, even more so because it houses a space-saver spare wheel instead of a full-size unit. The rear seat backs don’t fold down, so you can’t increase boot space.Styling changes with the introduction of the Monaro V2 Series II in December 2002; and in the V2 Series III from August 2003 were relatively minor. The VZ Monaro of September 2004 had a much gutsier look thanks to the use of the bonnet scoops developed for the Pontiac versions of the coupe that were built in Australia and exported to the USA.Only two engines were offered: a  supercharged 3.6-litre V6 and a powerful 5.7-litre V8. Buyers overwhelmingly went for the bent eight and the V6 was quietly slipped from the scene midway through 2003.The V8 came with a limited slip diff, 18-inch alloy wheels, premium stereo system, Variatronic steering, 12-function trip computer, automatic operation, road-speed dependent windscreen wipers, a three-position driver’s seat memory and climate-controlled air conditioning.Compared with the Commodore, Monaro’s suspension is less compliant to suit its sporting nature. Some owners looking for a cruiser and not a bruiser may find the springing too stiff. Others will grumble about road shock coming up the steering column.Both the V8 and V6 have great steering systems but the V8’s steering is sharper and more responsive than the six, again because it’s aimed at the sports buyer.Holden Monaro is not as quiet as the sedan, though it's better in this regard on rough roads than many imported coupes. There are front and side airbags for the front occupants, height-adjustable pyrotechnic front seat belts and ramps in the front seats to prevent someone slipping under the safety belt during a collision. ABS brakes try to prevent the need of the previously mentioned items.Traction control complements the safety package, cutting back power if one rear wheel should rotate faster than the other. However, keen drivers will find it’s too intrusive and doesn’t back off again quickly enough.Both Monaro models have an adjustable steering column, engine immobiliser, remote releases for the boot lid and fuel flap, power door mirrors, mobile phone point, a decent audio system with steering column controls, and driver's seat lumbar adjustment.The Monaro V6 and V8 are both genuine performance cars, costing much less than imports with similar performance and handling.Holden Special Vehicles (HSV) introduced its hotter variants of the new Monaro in December 2001. However, it didn’t call its car ‘Monaro’, simply tagging it ‘HSV Coupe’. The Melbourne based HSV operation said it wanted to differentiate its versions from the Holden original.The HSV body revamping gives the HSV Coupe a lower, meaner look. Changes to the body hark back to the days of the old 1960s and ‘70s Monaros in the ‘gills’ behind the front wheels, as well as cues to the old wheel covers in the new alloy wheels. Clever stuff.A fascinating version was the HSV Coupe 4, launched in December 2004 it uses a four-wheel-drive system to further aid traction. However, its added weight and the loss of most of the boot space meant it never really took off in buyers’ minds.Spare parts are still available for these Monaro and are pretty reasonably priced. It goes without saying that there are Holden dealerships in just about every town of any significance in Australia.Bits that are unique to the Monaro may not be stocked in more remote regions, but it seldom takes more than a couple of days for them to be transported from the spare parts facility.Service and repairs are often within the ability of the good amateur mechanic and there's plenty of underbonnet space in a large car like this. As always, don’t touch any item that may be safety-related unless you know what you are doing. And it's wise to have a workshop manual at your elbow before commencing.Insurance premiums are usually higher than for the equivalent Commodore, reflecting the sporting nature of the typical buyer. But the costs are certainly not prohibitive.Despite doubters saying the new Monaro would be a flash in the pan and wouldn’t last it continued to sell strongly for several years, before finally being cancelled in July 2006. Quite a few were exported to the USA and sold in solid numbers, though with their steering wheels on the wrong side for Australia. It will be interesting to see if any re-imports get back to this country.Monaros are generally bought by enthusiasts and get servicing strictly by the book. Ask to see the complete service record. Engines should start easily and idle smoothly virtually from the moment they light up.Manual gearboxes should be quiet in operation and pick up lower gears during all changes with no graunching. The change action isn't the lightest around, after all these are large cars with big-torque engines, but if one feels too bad be very suspicious.Make sure the automatic transmission changes smoothly and quietly, it should be virtually seamless except when accelerated hard.Check that the correct oil pressure is reached pretty well straight away. This is best done with the engine stone cold, preferably after and overnight stop.Look for signs of body damage and for crash repairs. If there's the slightest doubt as to the body’s condition have a professional give it a thorough inspection. We often see minor damage on the bumper corners as these are big cars and can be hard to squeeze into tight parking spots.Check over the condition of the complete interior, particularly for signs of sun damage on the dash pad and rear shelf. Look for scuffing of the front seat backs where people have squeezed through to the rear area.A car that has been pampered bay loving owner is likely to be in excellent condition - if it hasn't been thrashed and/or taken to track days.
