Sorry mate, loads of questions to answer, you could retro fit the latter system, its pretty much the same but uses the filler cap to piggy back the breathing pipe, you could try this, refresh the oil with a decent 15w40 mineral oil, new filters, oil stat, make sure the thing is all in spec then try to fault find it, clogged filters, old oil etc wont help you diagnose this and may well be the problem but to be fair the turbo might not fix itself.

Okay so, Oil change on friday along with filters, got a catch can coming which ill install and ill clean the **** oil out of the airbox etc. TIL landys have oil stats?

However i am more worried about the turbo if im being honest, its a later air research one (good or bad?), im assuming theres a way to check its getting oil? Also changing the oil will hopefully help the turbo?

Ill try get a photo of the turbo tomorrow

Thanks again!

Worn out rings and just a tired engine! my reasoning is that if the engines breathing oil into the air filter then the turbo surely is sucking some of that up and fouling aswell?

Little bit of oil like that will do no harm, it is when the oil feed pipe starts spewing it into the turbo that you will get a problem.
You could play safe and just remove the tube from the air intake, and route it somewhere else.
I wouldn't worry too much about the turbo, unless the pipe from it to the manifold is full of oil.
Like he says^^^^^, good service, set the tappets, and run it with the rocker box cap removed to check Head Gasket.

How can you check the HG by running with the oil filler cap off?

The usual HG failure on those engines is a cylinder, usually No.3,blowing into the push rod tubes, which will produce a distinctive "chuffing" of oily gases at the rocker box cap.

Okay so I've used the revive turbo cleaner, fitted a catch can and cleaned everything out.

Conclusion is the turbo now spins alot more free, Alot let smoke on decel and start up. Low down pick up and general response has increased (got up the big hill in 3rd rather than 2nd).
So I'd say it's worked, not sure how much is to do with the turbo cleaner I'm not sure..

The catch can has quite a bit of condensation guess thats normal maybe?

That is fine, engine fumes are hot, and contain water vapour, the can will be cool in this weather.

The catch can will fill up weekly with grey spunky snot that needs emptying, I give it a month before youu repipe it to atmosphere to save the hassle.

That is what I did when I had one of those. It wasn't even a heavy breather, the engine was new when I got it.
But why ruin air filters needlessly. I just lengthened the pipe, and put it into the chassis.

I wonder if the added performance is the cleaner going through the intake? Or just the turbo working correctly. Either way it still doesnt account for or fix why it seized up in the first place but with luck sorting out the breather like you did and fresh oil might have sorted it.

To be fair guys, my old bus breathes , not excessively but enough to coat the filter with oil, I just change it every six months to a year, its a daily drive too. I dont really notice a lot of difference when it gets changed, an oil change makes much more of a difference, the turbo on these really cooks the oil.

I used to change the oil on mine every 3k miles. That was quite a lot of hours, as the vehicle was used mostly around the farm, often at walking pace, and on little local lanes, so barely reaching 40 mph most of the time.
I used to use it for towing the cattle float, but it was a bit underpowered, so after a bit I got a V8 Disco for that.

I always had a car as well, you must have a spine and eardrums of steel if you are using that as a daily drive!

We have a lot of tugs at work and their hour meter reads almost the same as the trip meter, they get an oil change every 8 weeks.

Road vehicles seem to be the only thing that gets oil changes by mileage.

My tractors always got oil changed by hours, or annually if they didn't get used much, they didn't even have a trip meter, just hours.

And on the boat, the oil change interval is 250 hours, but I always change it just after 200 hours.

Our last boat was 50 hours, which I always thought strange as it was petrol, mind you the oil did get dirty.

Very variable. Some of the BMC diesels are on a 50 hour oil change, and they don't seem very different to my Kubota. But the oil is barely dirty when I change it, so I guess the engine is designed to put low demands on it's oil.
I guess the quantity of oil is important, the Kubotas take quite lot of oil. 8.9 litres to top of dipstick on my 43 horse.

Might expalin it 180 bhp, 4.5 litres of oil and 4500rpm

Yes. Quite a different scenario to 43 horse, 8.9 litres of oil, and 2800 rpm.

Was this an auxiliary engine on a yacht? I could easily run 50 hours in a week. Lot of oil changes.

Volvo penta 4.3glj v6 petrol, basically a marinised chevy lump, volvo paint theirs red and Mercruiser paint theirs black, but under teh skin same engine.
Very popular engine as tough old lump, range goes up to 8.1 litres, just imagine the fuel bill for that!
