Thanks for the quick replies guys
The main issues I was throwing parts at was a noisy waterpump and stuck Thermostat after the oil cooler split and threw oil all in the coolant system and stuffed everything up,
And I also had all the high pressure hoses for the power steering and hydro fan rebuilt as all were leaking,
So parts replaced are:
Oil cooler
Waterpump,
Thermostat housing unit
Heatercore as it was highly contaminated with engine oil
Bottom radiator hose
All hoses for the power steering and hydro fan with the proper mopar fluid,
Cleaned out all the intercooler piping
And full cooling system flush,
It's throwing a couple of codes which I checked by doing the key on/off
They are as follows:
P0340 which is cam position sensor
P1130 which has something to do with fuel pressure??
The jeep is running spot on apart from the smoke issues....
How can I clean up all the black crap as it's like bitumen lol
Thanks for the links guys
Edit:
I just checked and all 5 injectors are leaking and it's already had a section under the window cut out??? So I think it's had problems before.
