The 1KD-FTV engine and turbo in my Prado were replaced late last year after I cracked a piston. It's a new crate engine and new turbo. All was good for the first 1000km or so.
After about 1500km the engine developed a whistle/whine when cold/warm. It occurs at about 2000 rpm when the engine hasn't fully warmed up. (I don't thrash it, but it does take a while to warm up). The sound goes away once everything is fully warmed up according to my Scan Gauge.
The sound is a high-pitched whine that sounds a bit like a flute or wind noise coincides with the turbo boost spooling up at around 2000 rpm.
Any thoughts on what might cause this?
