yes, or out of cold side in to the cylinders, you allways find intercooler and hoses are wet but you shoudnt notice oil loss over the short termir\e ?
So if seals are not right, it can blow back in to the exhaust flow and straight out the back?
If it comes through the cold side it must burn as it goes through the cylinders, surely?? My hoses look very wet for new hoses!yes, or out of cold side in to the cylinders, you allways find intercooler and hoses are wet but you shoudnt notice oil loss over the short term
yes it does, they allways do thats why you have to see what is actually passing out of the turbo directIf it comes through the cold side it must burn as it goes through the cylinders, surely?? My hoses look very wet for new hoses!
Phew!it has to be bad for that and then it doesnt allways happen
Just a little puff when foot first planted.....if revved over and over she can start to puff a bit of black/white smoke....but that could be expected as the manifold pressure is low and you are pumping a lot of diesel into the cylinders.....this is where pump tuning adjustments can help - the Star wheel, the boost pin and the smoke screw.You are a star. A couple of months ago..................how many miles do you reckon?
Yours doesn't smoke though?

On start she gives a little puff of black, tanking up a hill pulling hard and she'll give a bit of a black haze but not clouds of soot....
Runs fine, and there is quite a bit of oil in the pipes.
I'd say she has done 1200-1500 miles in the last couple of months.
So another litre - and how many miles??
Clean as a whistle underneath. No leaks from anywhere, which is a positive I suppose.And it isn't coming out the bottom and being blown over the underside or burnt on the exhaust??
As James alluded to:Clean as a whistle underneath. No leaks from anywhere, which is a positive I suppose.
James is probably going to be right about the honing. But,
1. I can't get my head around the physics with the compression being so good.
2. I don't want to believe it
Hmm..........that's not good news then. I'm still stubbornly holding out though.............. nobody likes a quitterAs James alluded to:
The boring of the cylinders creates a screw thread, if this is not honed out, the minute screw thread can create a helical path for the oil to travel up via both capillary action and also when the piston goes up and down it draws oil and drives it up the screw thread into the combustion chamber.
Compression results will remain good as the oil is acting as the seal in the micro-grooves and seals against the piston rings.
The honing pattern in a cross shape, allows oil to be drawn into the honing grooves and stay there to line the bores to allow the pistons to slide, but they don't create a helical screw thread and as such can't be drawn all the way up into the chamber as the next micro-groove they encounter is one going the opposite way and the oil remains where it is and doesn't have a 'path' into the chamber - like the Archimedes screw,
