Eat your heart out peoples.
Look at those injectors, can't leak and carbonise the oil leading to engine destruction cos they're on the outside where they should be, the slightest seepage will be instantly noticeable, no more difficult to remove than a set of spark plugs for cleaning/overhaul when the time comes.
I must be getting old, can't remember now if my 70 with the 3.0 litre had an intercooler radiator on top, i'm inclined to think not.
What i do remember is how distinctive was the whistl from the turbo spooling up from as low as 800rpm, i used to drive Cummins engined trucks back in the day and you had the same sort of sound and massive torque rise from a similar rpm, it was one of the first things that attracted me to buying my first Cruiser, knowing how well set up they must be having rapidly rising torque available from such low revs.
Do you find yourself driving by the sound of the turbo alone Ozzy, it was what i found myself doing, there's a similar turbo whine from a good running D4D but not to quite the same extent.
The 70 series and 4 runner (Surf elsewhere) were i believe the first vehicles to use the 3.0 litre, previously 2.4, in the UK the first 70's with the bigger lump arrived in '93 and 70 sales ended in i believe '95 when the 90 series started to appear.
That engine also ended up in some Hiace vans (also previously 2.4) , whether the 3.0 litre ever got fitted to square shaped Hilux of the time i couldn't say, certainly not any that appeared in the UK, we bought a new Hilux in 2007 with the 3.0 litre but that was the then new shape mk6, first seen as Vigo versions from around 2005.
