Holden Caprice Problems

THERE'S no problem installing an LPG system on the Gen III V8 as you have in your car. The sequential injection system is the best. You lose virtually no performance with the system as it generally automatically switches across to petrol when driven hard and the fuel demand from the engine climbs.

YOU'RE doing well, and you're right that any car can be made to run on LPG. But while you can walk into most installers and buy a system for a Falcon or Commodore, there are few systems for four-cylinder cars.

HOLDEN generally holds parts for 10 years, but the VQ was released in 1990 so the company no longer stocks parts for it. Try phoning wreckers that specialise in Commodores, but the light will be hard to find because so few VQs were made. You could also try eBay.

A GOOD-LOOKING car tells the prospective buyer that it's been well looked after. Scratches and dents say the owner doesn't care. It doesn't sound as if it will cost much to get it looking pristine again. With the damage clearly visible, a buyer would expect a discount on the asking price.

THE V8 Adventra was a bit of a dog in many respects, but 20 litres/100km is a bit too high. The Adventra is a heavy old nail so I would expect it to be pretty thirsty. I would think it should get 16-17 litres/100km on average. The only thing you can do is to make sure all is well with the engine and the electronics controlling it, make sure your tyres are inflated correctly and that wheel alignment is correct.
