Total rebuild of the 1996 2.2 after I found a cracked cylinder wall in old block. After about 6 months of running perfectly, I started to note an intermittent puff of white smoke at startup, maybe 2-3 time a week. Last couple months, car would run fine, then make a quick 5 minute stop, then would not start. Would turn over endlessly, but not start.
Spark plugs and compression test good. Move to fuel system.
Replace fuel pump as it was still factory with over 200000 miles on it (might be a record!). Problem persists. Replaced filter at the same time.
Replaced spark wires as they were originals, same problem. Tested the ignition coil and it seems to be fine.
A couple weeks ago, car refused to start altogether. Just turned over until battery died. Recharged, nothing. Checking throttle body, found some oil down inside intake...check pcv valve, looked terrible, caked with oil so I am assuming this is where the oil in the intake manifold originated from.
Replaced PCV valve, and removed all the connecting hoses and cleaned them out.
Tried to start the car on starter fluid, and after running roughly for about 2 seconds (with puff of white smoke) car ran perfectly, and would restart while engine still warm.
But, in the morning, it won't start without starter fluid, then runs fine. (no noticeable smoke anymore at startup). I have attributed the no start to oil leaking onto the spark plugs at night from the air manifold, but 4 days after new PCV valve still not starting in the morning. About ready to get the sledge-o-matic out. :cursin: Any help would be appreciated.
