Alright, first and foremost I feel Like i abused my Z and trying to make it right. Recently i found that the water pump and radiator needed replaced, so I too a few days and replaced them both along with a new thermostat and etc. Yesterday I had a external coolant line break on me and well there was coolant everywhere (car did not overheat thankfully). So i tore off the plenum and swapped out all new lines and etc. Now I have an even more damaging issue, car has a really hard time starting and when it does it runs super rich. rich to the point where i can soak my hand with the amount of gas coming out of the tail pipe. New plugs, new coil packs, new lines etc. any tips? thank you in advance.

 

Edit: no longer smoking during idle but whenever I give it gas I get a ton of white smoke from the Driver side bank

 

White smoke = bad head gasket (usually)

 

Just got done with a compression test, all cylinder reading between 215-220.

 

Those are great readings, but that doesn't necessarily rule out a bad head gasket.

 

I am going to take it to my most trusted mechanic. nobody in my area works on Z cars but he mostly works on imports, so getting as close as I can. Will post with what he says
