Hi Steve
I had given it a few doses of Morey's injector cleaner a few thousand kms ago. More as a preventative and not knowing it's history. Not sure how the injectors are on the poor old thing.
It certainly has movement up and down in the compressor side. I hope it runs bushes, not sure how to find that out. The plate on it barely readable but will have another look.

Cobbadog, I have heard of adding a bit of petrol to the diesel to give things a bit of a clean but I'm not that game. If only it was that simple.
Thanks again for your help guys, I'm very grateful.
Cheers
Ash

Thanks Swishy
That may be the end result yet. Just don't want to throw money at it that I don't have to.
I get where you're coming from though.
Have a good one

Ah, yes! Many's the bloke who could tell tales of the bad old days adding a gallon of super to a tank of diesel to "smarten her up a bit",
Seen Perkins and even old NH250 Crummins get up and bark whilst throwing a flame a foot long!
Wouldn't like to be trying it any of these modern diesels, prolly blow the fork out of them!

Not that Lorry our 1991 FC144 Hino is all that new but I still don't think it would do him much good to put a splash of petrol in his tank, not happening. :unsure:

In the early 70s I worked for a company (that shall remain nameless), that had a fleet of 1418 Benz on interstate, a few of us used to put a blend in ( the super bowser was conveniently next to the diesel), smartened performance a little, and as far as I know there was no side effects. Don’t know about long term, as I stayed about 6 months. Mainly because I like to get paid, and the boss just loved to argue about rates.

Both petrol and diesel have the same energy content,all adding petrol does is increases the fire risk............of course ,a few guys I used to know ,had a lot of ways for doing that......insurance specialists ,we called them.

Well I'll call B.S to adding petrol to diesel
I have tried it and I dont give a rats what people say it didn't make 2 tenths of sweet f all difference
If you put straight petrol in a diesel it wont run hardly at all and is so guttless you couldn't pull the skin off a rice pudding

Cousin had a nice AB130 with a 4/236 Perkins ......very economical........he loaned it to one of his dipstick mates........one tank of petrol didnt hurt,second tank of petrol ,all the diesel was gone,and the DPA pump seized.and broke off the rotor....In the middle of nowhere,and no phones then either........but Ive heard that 71 series GMs will run on petrol without any damage to the fuel injectors.......in fact a farmer in SA was fined millions for running trucks on avgas........green dye,no tax.

Hi fellas
Interesting chats about adding petrol to the diesel.
I think if I have to do that, I've probably got more problems than I know.
At this stage it looks like I'll be getting a new turbo as Swishy suggested.
I've also been working on the engine brake mechanism to ensure it shuts off properly. Most of the linkages were very sloppy allowing it to sit slightly closed when off. I'll also add a spring to ensure when it's off, it's off.
Fingers crossed this should make a difference to the boost and reduce the soot. If not, the search continues........
