take the glow plugs off and turn engine over til it stops spitting oil out

I can't think what would stop it from starting, basically, too much crank case pressure, could blow seals, and gaskets, and even the core plugs, but to be honest, I would have thought the fact that it blew out the dip stick, should have stopped the pressure getting too high.
I am not sure how you blocked off the breather system, what did you actually do?
When it was running, and then stopped, how did it die, e.g, did the engine speed up, and then just die, did it sound laboured, did it hunt?

i'm guessing if its hydro locked, it vibrated and spat out smoke then died

It is really daft now i have sat down and thought about what i did...
What i did was cut through the pipe that comes from the blow by valve to the inlet pipe and pushed a cut down bolt in between and sealed them with a couple of jubilee clips so that the pipe was still in place but blocked off.
Then i started it and had it running for a few minutes and it started throwing out lots of smoke and spluttered and stalled....then wouldnt restart at all.
It was then i noticed the pool of oil on the floor.
When i looked at the drivers side of the engine i noticed the highest pointy that the oil is evident is the dip stick....

It wont be hydrauliced as u say it still turns over well just wont start if it was hydraulic then it wouldn't turn over

definitely sounds hydro locked to me
but he says it turns over really well if it was hydro locked then it woundnt even turn but y it wouldn't start don't no mate:nenau

The thing is, a Diesel will run on the oil, as mine did when the turbo pumped it in, so I don't think oil above the pistons will be a problem, it would just burn it, and rev faster.
I am wondering, when I was having all my issues "oil using issues", someone said something about there being a seal between the fuel pump and the engine, maybe it has blown that, so the pump is no longer able to pump the diesel.. As I say, I do not know anything about this seal, but it was a suspect when I was having all my issues, and filed away for later use, which I never needed.

sorry didn't no it would be that big :lol
:lol
if oil came out where the dip stick goes then oil deffo is in places it shouldn't really be, like i said i'm not 100% on the hydro locked theory but it does sound like that to me, maybe the cylinders aren't completely full and allowing it to turn over but not build up enough pressure to start, i honestly don't know, whipping out the glow plugs and turning it over would be my first port of call though, if it spits oil out of there then he knows thats where the problem lies

i've hydro locked a diesel before with oil, symptoms were exactly the same other than it wouldn't turn over, mine was from having my brother helpfully topping up the oil for me, he toppes it up enough to come out the air intake when the engine was turn over :doh :lol :lol

First thing i'd do is undo what you have done with the breather pipe as it's causing back pressure hence the oil pouring out of the dip stick. Engines need to vent off the hot oil gases either back into the induction system or to air via a mini filter or a catch tank with mini filter fitted

I have returned the pipe as it should be....i got a piece of 15mm copper pipe and placed it between the piece that i cut and secured with jubilee clips...so it is breathing as it was originally...
Richo, when you hydro locked yours with oil what did you do, just remove glow plugs and spin it over and did that clear it and allow it to run?

That was kind of him...:augie
When the diesel is sprayed in the top of the cylinder, it is mixed with air, and basically there is a lot more air than diesel. It is the air that is compressed. In your case, instead of air being drawn in, oil was, which does not compress...
Your Hydrolock was where there was so much oil in the cylinder, the piston could not compress it, so it effectively seizes up the engine. The same goes, when you take water in the air intake, you get so much in the cylinder, that it can not be compressed, so stops the piston dead... the problem is, if you are driving, the inertia of the car still tries to push the piston up, and something breaks or bends...
By blocking off the crank case breather, he was not putting any extra oil above the pistons, and for it to get there, it either had to get pushed past the rings, or down the valves, but the quantities would unlikely be enough to hydrolock the engine.
cant c that being ur problem as urs is turning over and if it turned over enough times to make battey go flat I would say that if oil was in there it would have gone out the exhaust port same way it would of gone if u take the glowplug out so don't c that helping u if u c what I mean
