This has to be the most infuriating rescues I've ever taken on, the Graphite Green Metallic 9-5 Aero is absolutely intoxicating; the colour is just sensational, and with the modifications made to suspension, braking, and tuning have helped it to drive impeccably well. But, and there's always a 'but' with these projects, the oil light is back on yet again.

Even after a replacement engine had been fitted, it covered a few hundred miles and came on again, at higher rpm's the light stays off, but pull up at traffic lights or leave the car at tickover, the oil and warning lights flick on again. What's more concerning, is that the engine appears to be tapping, which could mean another replacement engine.

Of course, there's only so much I'm willing to do, but after spending a further £1500 on bodywork, cutting out the corrosion in the rear arches, welding, fully refurbishing the front bumper, side skirts and rear boot lip and all new genuine badges, I just can't quite give up on this one.

The numerous work gone in to this is almost too much to list, but with the replacement polybushed subframe, Bilstein B12 and Eibach springs, refurbished wheels, new Michelin tyres, upgraded intercooler, JT exhaust, upgraded brakes and callipers, not to mention replacement engine I, clutch, water pump etc, this has been a labour of love for sure.

I just wish we could identify the source of the oil pressure problem, without using an entirely new donor car, needless to say, the saga of the beautiful Graphite Green Aero continues...
