Turbo question

[ste68blue]

yes i see what you mean geoff...but i am happy to try anything at the moment.

would it work in a similar way to a petrol engine when its flooded and the spark plugs dont spark properly, where if the glow plugs were saturated in oil they would not glow hot enough?

Would it be worth spraying some easy start or summat in whilst cranking it over?

don't want to use it too often but if it fires for a couple of turns then u no the compression is ok and its fuel or air have u taken the air filter off as with all that oil could of pushed back to air filter and not letting enough air to start:nenau

Now this may be a long shot too....but here goes...

I also removed the turbo - wastegate vacuum pipe and put a T piece in for the boost gauge i bought and slipped a piece of piping on, if say the pipe wasnt sealed properly or something would that stop it from firing up?

sorry for not mentioning that earlier, i forgot i had done that.

I know that wouldnt explain the oil pool etc but would or could it stop it from firing up if the pipe wasnt sealed properly?

Hi all, i stripped the blow back valve off and the intercooler and the associated pipes and cleaned them all out.

the i put it all back together but sealed the pipe from the blow back valve to the air inlet and ran the car, all seemed well to start with then lots of smoke....and it stopped.
I then noticed under the car a pool of engine oil....

I think i have traced the oil coming from the dip stick as that is the highest point that oil is visible.

I then realised i had mis-interpreted the thing people were talking about with the blow back valve pipe and it shouldnt have been blocked off as this would then cause back pressure in the engine...

The problem is the motor wont start now....its turning over well but quickly drains the battery.

can anyone tell me what i have done and how to fix it please?

Any help or advice is much appreciated

shouldn't stop from running just get over boost when under load

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.

Back pressure if high enough will easily force oil up the dip stick tube, past the piston rings or past the valve seals but no it's prob not the full cause if the engine has hydrolocked but it wouldn't of helped matters:augie
Have you cleaned out the intercooler ? as they can hold a lot of oil in them, I know when I soaked mine in paraffin to clean out the oil it took 3L IIRC to fill the thing up

 

[ste68blue]

I cleaned the intercooler when i originally had it removed at the start with petrol, laid it upside down and filled it with petrol and left it for an hour, emptied it out and repeated.
Then once i had emptied it the last time i left it on its end and dried off any remaining petrol before refitting.

When i had the back pressure issue, to try and find where the oil was coming from i removed the intercooler again, but there wasnt any obvious sign of any engine oil in there...if that makes sense?

Have u checked air filter yet

 

[ste68blue]

i havent checked it yet, but surely if there is no obvious signs of oil in the intercooler the air filter would be clean too...?

if u take off air filter pipe to turbo and try and start car if it wont start try easy start at least if it fires it would of burnt of any remaining oil round glow plugs

With the breather disconnected, as it was at the time, there is not really anyway for the oil to get into the air side of things, so I think you are barking up the wrong tree...

The Oil will have blown out the dipstick, as that was the place of least resistance after the breathers were closed off...

How much oil is there in the engine bay and under the car, are we talking litres, or just half a cup full sort of thing.

I think at this point, I would be changing the fuel filter pipes for clear, even if it is just temporarily and make sure that the fuel pump is drawing fuel through.

 

[ste68blue]

the pool of oil is about a foot square...so probably not lots of oil....

I would say that is a bit more promising, when I was fault finding mine, I put my thumb over the breather out of the rocker cover, and it pushed the dipstick up, so it was just about 2 inches up, and sprayed a small amount of oil out. Luckily, I took my thumb off, at that point.

I would definitely be looking at the fuel pump side of things, see if you are getting fuel being pulled through.

Still trying to find the thread it at the moment.

when you say it is turning over well, does it sound like it has compressions, if it spins easy and faster than normal then you may have valve damage, if compressions sound normal then you may just have more oil in the combustion chamber than it can cope with, if so then as long as you have put the breather back, the best bet is to tow start it, Rick

Your the man that would know, what was the problem with the fuel pump, vacuum pipe, and oil?

I can't find the thread, but I know when I had the issues with mine burning oil, there was a plausible reason why the fuel pump could be causing it.... any ideas?

thats pretty much what i said to start with :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

Okay chaps an early start....

I was thinking about it last night and thought about once when the battery went flat and for some reason it must have drawn some air into the injector pipes and when i cracked loose a injector pipe and spun it over it coughed and spluttered but started, once i tightened the nut back up it was fine...

So i thought first thing i will do is crack loose injector number one feed and spin it over...well nothing is coming through at all...so no fuel.

Any ideas?

 

[ste68blue]

Another quick update...
As there didnt seem to be any fuel showing I took the feed pipe off of the fuel filter and cranked it over...but nothing us coming out of that either, I was expecting something to be pumped out...but nowt...

I am well and truly stumped....

immobiliser kicked it on back of pump is stop solenoid get a volt meter and c if u c voltage at this as if this has no voltage then no fuel at injectors :thumbs

Morning geoff, can you just explain a little more please?

the pipe from tank no there will be no fuel coming out of that pipe when cranking as the ip draws up the fuel so now u have no fuel in filter or pipe to ip
