@mpower: I took of the entire Intercooler this weeked, thier was indeed some gunk build up, but nothing much to talk about, i cleaned it throughly. Still getting the same problem though. I also took off the glow plugs again, and placed them back to ensure they were placed correctly. Same problem.
@godforbid: No Oil in glow plugs, however i did see an oil leak at the intake in the intercooler, but since i cleaned it nothing showed up yet. however thought there is a unit just lower to the intake, i believe it is the turbo charger (not sure) i am seeing an oil leak on that unit, i dont know if this could also be a problem.
However guys, after replace the glow plugs and cleaning the Intercooler, i still got the hard start, I then reved the engine for about 30-45 sec, all i could see & smell was diesel smoke, after that time the smoke eased, and i switched off, and the engine turn over like brand new....no tumble just start.
So i am begining to wonder if the pump and injectoer wants servicing.
