Hello guys just looking for a opinion on if indeed this turbo is on its last legs and should be replaced ASAP. I'm pretty confident its toast but I just looking for any reason it might not be I guess. Back ground on the car 2006 BRM with 180,000kms/112,00miles on the clock. I have recently replaced the cam and timing belt service with all new parts at 170k as well as put in a malone stage 1.5 tune. Any reason that any of these would lead to premature turbo failure? Could the 1.5 tune put that much stress on a turbo in 10,000km to blow it? Could metal/cam material from cam break in cause the CHRA to go out that easily?
From the below videos and pictures I have gathered that there is no apparent physical damage to the turbine or compressor wheels that I can see with my scope. Axial play is basically zero, radial looks like is some in the video you can see but it doesn't contact the housing at all. Compressor spins freely, I even side loaded the compressor wheel and spun it to see if I could get it to touch the housing and nothing.
The one thing that I did notice that on the compressor outlet recently there has been alot more oil dripping out of it and onto the transmission like a good slick/top of tranny had little puddles. Is this CHRA failure and oil is passing? Can prolonged idling at cold (minus 40 degrees Celsius) start cause
that much blow by?
Any way let me know what you guys think, car is parked until I either decide to order a new turbo or limp this one along if it is good for another while. The sounds in the video aren't that loud but when you actually drive and load on the boost it sounds very high pitched and loud, almost like a really bad alternator.
