Hey everyone. My wife overheaded her 95' Contour GL 2.0L Zetec last Friday from a blown top rad hose. She let it cool off and drove it another two miles into a little town where they changed the hose and filled her antifreeze. They drove the car and said it was smokeing (white exhaust) and said the head gasket was blown. After they shut it down it wouldn't start again.
I had it towed home and started on it. I pulled it all apart and found antifreeze in cylinders #2 and #3. The head gasket didn't have any breeches, but the head was warped 0.004 in the center where the antifreeze was found. The local machine/motor shop decked the head 0.010 and installed new valve seals. They cleaned the head and I picked it up last night.
While waiting for it this week I cleaned the block with a razor and a wire brush and all cylinder bores with rubbing alchohol and cheese cloth and blew then out with compressed air. I changed all heater/rad hoses and bought new plugs for it.
Last night I put the head back on with all new intake/head/exhaust/thermostat gaskets. I torqued the head down and reinstalled the lifters to their original locations. They had been stored upside down in oil all week. I then installed the cams with new cam seals and set the timing with the block pin and timing tool. I rotated the cam pully and let the cams do a full rotation and the put the pin back into the block and could then slip the tool back into the cams. I figured that meant the timing should be fine.
I put it all back together and started the car. It started knocking. My heart sank. I tryed to comfort myself and thought a valve needed to seat so I let it run for 30 seconds. Puffy white smoke poured out the tailpipe while it ran. It does not smell at all sweet like antifreeze and it has me puzzled.
I pulled all the plugs and they are as clean as when they went in. No oil/antifreeze evidence. Shining a light into the plug hole reveals a clean dry piston. What the heck?? What's causing this white smoke?
I started the car again to see if the knock would quite down. Let it run for another 30 sec. Same deal.
Waited ten minutes - started it again. Same deal. I idles smooth as silk, but continues to knock and smoke. No idea what the heck to do. I think I will head back out and pull the valve cover and re-check the timing.
No sure what else to do. Any help/experience/advice would be greatly appreciated. Thank in advance!
