OK where to begin first of all it's a 89 325i. last week the throttle body gasket for the coolant went bad and it had to replace that. i made a gasket after i drilled and tapped the screw because it decided to break on me. That sucked but it happens. The same day my water pump starts leaking on me so i got to replace that. Finally think thats fixed take it for a test drive and my distributor cap went bad. I'm PISSED. I go home for the weekend and notice it is running hot. it stays at 3/4 i figured i needed to bleed the system no big deal. i replaced all the shift bushings, changed the oil and oil filter housing, and changed the transmission fluid. i go back to my apartment and decide i am going to bleed the system. i park it on an incline warm it up leave the cap on, and turn the heat on. I open the bleed screw and nothing but air comes out. I did this for about 10 mins and took it for a test drive and it overheated completly to the red. I then parked it waited for it to cool down and repeated the process several times. I searched on hear and read all the post i could find but im not having any luck. it seemed things got worse after i bleed the system. I still don't have heat either it just blows cold. before i would have it sometimes it seemed to just come and go as it pleased I'VE BEEN WITHOUT A CAR AT COLLEGE FOR PRETTY MUCH A WEEK AND IT'S GETTING OLD. I need answers, any suggestions would be greatly appreciated thanks in advance Ben!!!
