While replacing my wastegate actuator I checked the compressor end of the turbo for play - and there is some. Odd, as 1500 miles ago during engine rebuild it was absolutely fine. Possibly the low grade oil I ran for 1000 miles to aid bedding in the rings has caused this though the oil analysis merely said that wear metals were in accordance with post rebuild bedding in - no mention of yellow metals which presumably turbo bushes are made of.
Anyway, given there is play, better to replace it now before it fails and puts compressor debris right through the engine core? Is that a typical scenario when they fail - or is there some other symptom that gives prior warning?
Any reason not to replace it with the cartridge in the link below? Any other suggestions anyone?
