Hi all, Just had the same experience on my way back from WA. Load siren sound above 1500rpm. Had the Hilux flat towed to Penong (400ks) and $2500. Fitted a new Toyota turbo for $3000 at a great mechanical workshop there.Lux only done 190000ks. so was a bit shocked. My thoughts?? not worth risking the front of the turbo going and then one is up for a new engine.So bit the bullet and got home, all going like a train again.
