Are the pistons oversize at all ?

Not

Not as far as I'm aware
They all had these numbers. I suppose it should be possible to look them up to find out.

I cleaned up the air pipe turbo to intercooler, which is galvanised and painted it as the oil sump pan, also fitted a set of Blue Silicone Intercooler Hose Kit which looks a bit posh.
The intercooler fins was a bit of a mess, previous crud from the now blanked EGR had left deposits of carbon and sooty build up inside everything. I'm Shure this device fitted to everything destroys an engines ability to breath, especially if it's direct injection.
I got a new intercooler which was not full width but does have a slightly bigger airflow, but mostly because I could never repair the corroded and damaged fins. So it could never perform as well as a new one.


It's made by a company called Gravity model GV0 801 was a straight fit with a little pushing and pulling, and was an easy fit.
I didn't want the full with intercooler covering part of the radiator, although I think they will cool the air a bit more increasing boost and no doubt power. But I want a reliable tractor lol. Not one that overheats!
With other small things replaced such as the oil filler cap rubber seal, which when I removed it, was beginning to crack if I bent it over.
But everything just came together nicely from here on.new copper seals for the fuel rails and injectors. Everything torqued down as specified in the big book apart from the sump as it's on a compound gasket, which may leak but we'll see.

Got a vid of the engine running, and hey no smoke but it won't upload!

It's running great

Someone posted on this forum that they fitted a gas flow head from turners I think and one of their comments was that the sound levels at idle seemed a lot quieter or less tractor like
Yours ?

Good for you.
I once came across a chap who had fitted an intercooler from a bigger engined vehicle a Renge Rover or summit.
He reckoned it boosted both power and economy. Well he would say that woudln't he.
But the standard intercooler has long been seen as not much cop and a bit of an achilles heel.
Maybe one day I'll be able to get to my 300tdi and do something about mine rather than just cleaning it.

I'm Shure a bigger intercooler would push some more power, but the one I got is suppose to have more flow and cooling fins so it certainly does no harm. The old one was not worth cleaning out because the fins would never be goodno amount of work short of a re-core would do any good fir the auld one

It's aboot the same old truck sound wasn't loud before and I was still able to sell the head,valves and guides being pretty good.
But a steep hill coming up to Midmar from my woods required second gear before, even my Subaru XV turbodiesel requires 2nd gear to get and keep going before being able to get into 3rd gear.
But I can drive up in 3rd gear now all the the way. So there must've more low down torque.
