Hi guys Ive had my 04 turbo diesel for about 5 months now.
I brought the car and this ticking was very faint but over the last 2 months its gotten a little louder.
Im a bit worried as the 1kz 3L (or maybe it was the 2.8L) was renound for spinning the big end over 200k
This ticking noise doesn't happen at idle it starts ticking at aprox 1200rpm and get louder and faster as the RPM rises. It happens on free rev and whilst driving (accel and decel)
defensively coming from bottom half of motor.
any ideas?
