Engine Mechanical problem
1993 Nissan Sentra 4 cyl Front Wheel Drive Automatic 221000 miles
Hi, I need help with diagnosing my son's car problem.
The problem stem from the car being ran idle in park with about a fourth tank of gas until it overheated or shut off. The oil was burnt so I changed it and the coolant had turned white and I changed all that too plus bought a new radiator because the plastic part had melted and had a small hole that leaked. All fluids are where they suppose to be as I double check. The oil looks a little brown but maybe because it has sat up almost 3 months but it is not not milky or anything like that. When I crank it it idles fine but when I drove it about a mile or two runs rough. It kinda stalls when I come to stop and reaccelerate. It is kinda missing a little bit too.I check the spark plugs, fuel pump. Etc. There are no leaks anywhere.
do you think it is something electrical or oxy sensor or something? Do you think there is engine damage, valve or piston head gasket or something? Also there is white smoke coming from the exhaust. What would be the best way to determine and do you think after an incident like this the car is finish? Someone suggested a compression(how much is it $?) Test and would this pinpoint the main problem or all? Can the compression be done same day? The car has been well maintained, but what can I say about teenagers.
Thanks Bob dusable
