tell me what you think the problem is.
Background:
About a month ago I installed a starter. The engine ran okay, but a little rough. the coolant light stayed on al the time but the gauge read mid-range (normal). I topped up the coolant resivior several times thinking i had air pockets in the system, and it was just working the air through the system. about two weeks ago I seemed to get the coolant leven correct, becasue the light stayed off, and the gauge read normal. but around that time I noticed the idle would surge up to about 1500 rpm. and if i had the AC button on, the car would rev to about 2000 rpm. turning off the AC usually allowed the car to go back to 800 rpm. but occationally, the idle would surge even when the AC was off. the other day i tried to get to the bottom of this so I had the car started and idling, and i started to press on the vaccum hoses jiggling them around listening for any changes. sure enough, when i reached under the throlle body and pressed on the hose under there, i could hear a hiss of leaking air and this corrosponded to a change in RPM. it seemed like there was a loose hose under the throttle body, and if i poked it just right, so that it was not leaking, the idle seemed perfect. so, i figured I better take off the hoses leading to the trhrttle body, and see if i could get in there to see exactly what was loose. i took off the large intake boot, checked all the electrical connections, as well as the hoses and the book itself for cracks, etc. I didnt see anything that was too obvious, so I put it all back together, and replaced a couple of suspect looking hose clamps. When i went to sytart the car the starter turned about 1 revolution of the flywheel and stopped cold, like i'd left a wrench in the engine bay. I checked. saw nothing and tried again. same thing. one turn, then an abrupt halt. scarry and unnatural. i looked in the engine again and then i saw that I'd failed to reconnect the electrical connecter to the air flow meter. I reconnected this and the car started, but that is when i noticed the strange white smoke. the smoke does not look like blue oil smoke, ive had enough british cars to know what that looks like, but ive never had a blown gasket so i dont know if this is the dreaded white smoke. How could I have blown a head gasket, or cracked the head? the car wasn't running? it never overheated, although the last time I had it out, I do remember the temp guage in the dash was bounching all around, it looked like a bad sensor, or a loose electrical connection, becasue it was bouncing from full cold to mid-temp and back, snapping back and forth. Ive had the sensor for the guage go bad twice in a year, so i thought it had gone bad again. but even with this erratic behavior of the guage, the highest it ever read was mid-level, at the most, a touch above mid-level, but no hotter. so what gives?
the video probably teels you more than this whole backstory, but i'm worried about a cracked head.
help is appreciated.
