1990 Pontiac Grand Am; 2.5 Liter L4 engine w/fuel injection, automatic lockup, EFI, and balance shafts; 3-speed automatic transmission; 111,245.1 mi. (Approx.)
I'm driving down the road and my car starts to shutter in low 2nd and low 3rd gear. Then the "CHECK ENGINE SOON" light comes and the car makes a loud, sqwealing, whining noise and then dies. I pull the car over to the side of the road and try to start it. All it does then is the starter engages, and the engine jumps. I've had people tell me that it could be a few dropped valves, a broken timing chain, a thrown rod or main bearing, my torque converter could have went out, I may have broken the crankshaft, or I just need the engine rebuilt. I would like to know what it might be and hoow much it might cost.

The oil in the plug wells is a leaky seal. The seals are simple to replace. Take off the cover on the valves and the seals are inside. Valve cover gasket usually comes with these seals. Cautions are not to over tighten the nuts when putting the valve cover back on and you might consider replacing the plug wires if there is any engine miss or tough idle, etc.
