Kind of difficult to tell where it is coming from in that image.
I would de-grease it, fire her up and see where it leaks from. Is there a chance it's diesel mixed with soot being pushed back up the side of the injector if it's not sealed properly? Or diesel is leaking somewhere, the injector itself or the union and what you see if manky diesel soot mix?
Is it blowing out with the piston cycle or anything?

Am 100% sure its oil , its only blowing from the area under the injector

Made sure that they are tied enough , but keep getting oil once accelerating and the engine power becomes low

Loss of power and increased "oil" with acceleration sounds to me like either the injector is not sealed properly (might be tight but could be sitting on a badly seated washer etc.) and is leaking diesel/combustion gas and soot back up, or your HG is blown and the loss of power is from is being low on compression/not firing properly and the oil is blasting out the side from an oil gallery going up to the head.

No not from it its sealed properly

Probably the injector is not sealed right, but the HG is just being replaced!

if you look at the head gasket between 3 and 4 injectors is there a tab of gasket showing with 1 ,2 or 3 holes

Even though i have make sure that its sealed properly still keep getting the same thing once kicking down on her

Why did the original HG fail? What procedure and preparation did you carry out on the block/head before refitting the new one?
Amer

To be honest I don't know what do you mean by tab , but If i got what you mean, no nothing is visible to me, the only thing that looks wrong is the oil under the injector number 2

Right looking at the photo I can only really see a mass of oil around the area of injector no. 2.
Either, it is not oil at all, it is diesel mixed with soot (touch it and sniff it, does it smell like diesel?) in which case it is going to be injector related, so diesel pipe union, injector itself or very badly sealed injector causing almost no or poor combustion leading to a diesely mess being blown back up the side of the injector this could also explain power loss - any chuffing sound with engine running? Can you not see stuff bubbled or spraying out?
If it is oil and it is not the rocker cover (and that probably wouldn't worsen with acceleration unless the crankcase is pressurising and blowing oil out) then is it coming from your cyclone breather or associated pipework (this would not explain power loss unless it's a separate issue), or it is the HG blowing oil out the side, and also as part of the HGF you have compression issues causing the low power.
There is not a whole lot more it could be. I would start by cleaning it all up and diagnose the locations of the oil leak rather than a massive splodge of oil on the side of the head.

It
Was buried on the same area of this injector. I have taken the Head to an expert who have puted on 4psi water pump to test it ,then we found out that one of the glow plugs hole was drilled before and it's wide . We have fixed that with a sticky material for such issuesand pressed the glow plug with it. Then we ran the same test and was ok . After that i a bought a new HG repair kit and put everything back on its place. Ran the engine for about 3 hours with out moving the vehicle and no problem was seen. After I first tried to ride the vehicle i notice the voice i found the bits under the injector is loose and the oil all around the injector as you see in the picture, i fixed it and make it tid . And still getting the same problem

Pull the injector and the copper washer, replace the washer and clean out the bore and the seating face of the injector bore, clean up the injector with a wire bush. Add a tiny smear of hylormar or grease to the washer to stick it onto the injector and gently place it down the bore then refit the clamp and torque down to the specified torque.

if gasket is fitted correctly a rectangle piece of head gasket should protrude between 3 and 4th inector this has the hoes stamped through denoting the gasket thickness
the piece with the 3 little holes top eft of gasket in the picture

The problem was on head it self, apparently the fix we've tried to do didn't work out, the oil is blowing up from the glow plug it self. No i have to replace it another one.

So was it sooty diesel blowing up? What sort of repair did you do to your GP bore?
Thanks for keeping us posted.

Once we've tested it, it was losing compression inside the GP bore, so they only solution we had is to replace the whole head or put some sticky 2 finger material with the glow plug to see if it loses compression , once the material dried we've tested it again on 4psi and it was Ok. But that didn't work out on the actual engine compression. So now i have to look for a 2nd hand head and see how it goes
