when idling and when I take oil dipstick out it is pournig oil - is this engine done???

Thank you in advance

If you have oil coming out the dipstick tube, this indicates excessive crankcase pressure to me, and removing the dipstick relieves the pressure while also pushing oil out the dipstick tube, that becomes relieved when you remove the very oversized (relative) oil fill cap. I suspect the following;
1)Crankcase breather filter is plugged
2)Crankcase breather vent hose from the filter housing to atmosphere is plugged
both of these situations would be instantly relieved by the fill cap
3)Turbo seals are leaking excessive pressure into the crankcase
4)Cylinder rings are worn or cylinders are glazed enough to allow excessive blowby for the crank breather and the dipstick tube, but not also the fill tube
5)Significant internal cylinder pressure leakage from time and wear indicating an overhaul is or is soon to be required

All the chemicals in the world to clean the oil residue from the surge tank will do nothing to solve the crankcase pressure issue.
