Turbo advice

Hi, Julian.
I see your quandary - miles done Vs cost of repairs. It is not the boost output that is the issue with turbochargers. The main cause of turbo disintegrations is the speed at which the little devils operate. Because of this speed factor, along with the working temperatures, the slightest fault can end up in a catastrophic failure, not unlike a comparatively delicate bird going into a jet engine and wreaking havoc with the turbines.

There are folks on this forum who know way more about such matters than I but I would be hesitant about putting it back as is and there is no way that I would recommend that you do so without at least seeing some detailed photos of it. I think some of the more qualified folks on here would appreciate seeing some photos before offering much advice too, if you are able to arrange that.

Just my 0.02.

Julian, something has gotten into the intake and caused that dammage.
It may run fine but the compressor wheel is likely out of ballance due to the visable dammage.
If it is out of ballance the vibration created can stress crack the shaft and the turbo dump it's innards down into the cylinders. Old D330's had a gasket containing a screen in the piping to prevent this but haven't seen any screens in modern engines. Should maybe overhaul it before anything happens.

Thanks chaps, I pretty well knew that it needs repairing, I don't mind spending money if it's needed but I'm always happy for a second opinion as it's easy to just go renewing everything and ending up broke😞 I've heard of cases were the shaft bearings and seals have gone leading to the engine running off its own lubricating oil and revving up uncontrollably to destruction!

Anyway, I've had some money saving luck today so I'm feeling a bit better. The alternator (and a tensioner jockey pulley) had shot bearings and I've managed to pull it apart and get to the bearings to replace them. I've got the best bearing suppliers in the UK just a few miles from my door and about $15 should do the job👋 This is good because the alternator is a hefty lump, 24volts and isolated earth - I could see the cost of a professional rebuilt being pretty steep.

Ta, Julian

Hi, Julian.
Good to hear that you had a win with the alternator and jockey pulley bearings, Didjya go, "PHEWWWWWWWWWW!!!!!!!!!!!!"?

I cain't figure what was happening when I first looked at your original post 'cos there just was not a photo to be seen anywhere - - which is why I suggested that you load some photos if you could. (Gentle headshake happening here.)

Just out of curiosity, how does the RR/Perkins Eagle perform? I've never seen one here in DowNunder and have only ever heard of a couple of them here.

Well, more good news, I took it to a place near me in Liverpool called Marine Turbos, and the chap said that probably the impeller can be blended and weld repaired - just some labour and £100 in notes👋 They had some turbos there the size of 45 gallon drums!

I don't really know much about the Eagle as like everything I do for a hobby I'm a jack of all trades and master of none! The Rolls/Perkins engine was never as common (by a long way) as the Cummins, but by all accounts it's a sturdy lump, last for a million miles and I've found it very willing to lug away up inclines. Starting on a cold morning is old-school Diesel, lots of cranking and clouds of smoke😈 When warmed up though the exhaust is very clean.

I took a photo of it for you, obviously the turbo bit is missing at the mo! Did you get ERF's down under? Like Fodens, once they were a very popular machine on our roads. ERF's got taken over by MAN who after a period dropped the ERF name. There's no such thing as a British truck industry these days - I blame the effing politicians who can't think beyond London, the city and finance!

Hi, Julian.
Thanks for the photo. It's a fairly solid-looking lump.

Yes, we did get ERFs DowNunder, along with Fodens, Atkinsons, AECs, Albions Scammels, Morris, Austins, Bedfords, maybe a couple of others too that have slipped my memory.

We got this little gem too.

My Uncle bought a used dodge pickup with a Cummins diesel (68K original miles). He'd start it up cold, run up to the corner store for a pack of cig's and be home 5 minutes later and shut it off. I kept telling him that he should let it warm up, drive it and let it idle & cool before shutting it off. After several months of these quick 5 minute trips he complained that oil was dripping out of the tailpipe. The bearings in the turbo were shot, and 1/4" of the impeller wheels were worn off. I warned him that what's missing from the turbo impellers HAD to have gone through the engine. He bought a rebuilt turbo but a couple weeks later asked me to come listen to the funny noise coming from the engine. My uncle started the truck cold and revved it. I told him to stop and let it warm up first. Less than a minute later he revved it again and the engine screeched to a halt right then and there, it Seized up solid. My Cousin took the engine apart and found that 3 cylinder walls were scored and there were a few scored bearings. ...Know anyone looking for a nice '01 Dodge 2wd 3/4 ton pickup with a blown motor?

Hopefully you won't have that kind of luck but I might take a look inside the engine if at all possible.
