Turbo Oil Leak

[bobk]

While rooting around the starboard engine I noticed a very slight oil sheen on the outboard turbo (6V92TA). This is from what I'll call a cover plate on the cold side. Is this a serious problem that needs to be addressed? And if so, is this likely to require a complete rebuild or simply a seal? Morgan can pull it if we need to. Any recommendations for where to get it serviced in south Florida?

Ups goes north. Derek are you there?

Derek did one of mine a few years back same thing just some oil it is best to fix ASAP. Bob I think to do one seal it has to come apart so you do them all But Derek is the one to talk to.

It could also be from ingested breather oil. You'd have to look at the intake side of the compressor and see if there is oil there before condemning the seals. Definitely find the source and address it. Neglected turbos go boom. So does the price.

Can I inspect it simply by removing the air cleaner? Would I be looking for a trace of oil film or puddles?

Thanks,

You'll have to remove the air cleaner and hopefully access the discharge side of the compressor. A very thin film or dusting of oil on the intake side is not unusual, but if it's wet or grimy on the compressor wheel or inside the housing probably means it's pulling oil over from crankcase ventilation. But if that is clean and you see wet oil in the discharge nozzle that probably indicates a seal. Also check for excessive radial and axial play in the shaft. That could be an indication of bearings on their way out which will also cause an oil leak.

Many thanks. I'll try to get at it this weekend, just not sure if I can bend enough in which case I'll have my mechanic check it.

I'm just an amateur mechanic but if the turbos not doing its best you can get low compression and black soot. Related to previous posts???
