Had my shade tree mechanic friend come up and take a look at it yesterday with rad pressure tester. System seems fine and is holding 15- 16 lbs just as it should. Oil dipstick is not milky, trans dipstick is not milky, no moisture on oil cap and lastly neither oil is low (cold OR hot) which leads him to believe there’s no active leak into the radiator and all that stuff in my rad is residual disgusting ness that the shop didn’t bother to flush out. Looks like both when they put new rad in and recently they changed the lower intake gasket they just drained the rad and filled it back up when done. Basically they cut as many corners as possible. For example instead of replacing one small screw my distributer cap was zip tied on. Anyways that’s what happens when ur dumb lol right and before you say it, yes I have learned my lesson and from now on I will be the only one performing ANY work on it. As for the Heater Core the Previous owner (my mothers junkie boyfriend) completely bypassed the Heater Core by disconnecting both hoses from firewall and clamping them together, Oil smells like gas.. I think... can’t tell if it has a faint smell of gas or if it’s just burnt oil plus placebo effect of reading that oil smelling like gas is sign of bad injector. Either way I just bought new distributer cap and rotor kit (Duralast gold cap and rotor kit part#DR2030G), new plug wires (Duralast part#4669), and New spark plugs (ACDelco part#41-993). Changing Oil and oil filter as well today and tomorrow I am going to Super flush the coolant system as best as I possibly can. ACDelco mpfi spider injector is next on my list if ignition tune up doesn’t fix the misfire and If any new oil pops up in rad after full flush tomorrow and my dipstick still smells a little like gas, then I know I have a problem somewhere, and will be back on here asking you all for your insight. Installing cap, rotor, plugs, and wires right now will provide update when done.
