Re: 2000 mustang gt engine problems! Advice?
Wow, you're lucky that engine is still runnable! The Ford modular SOHC & DOHC engines are interference engines, so if the timing chain breaks, and a valve is stuck in the down position, which is normally the case, the piston comes up when the valve shouldn't be there, and whammo! Usually the engine is shot, as there is extensive valvetrain and piston damage. One or more of the valves might be damaged, giving you those symptoms. Is the check engine light on? If so, have it scanned for codes. Who did the chain replacement? I'd ask them about it, and if you're going to keep the car, maybe do a rebuild on the engine, or find another decent engine to replace it with.
