is it hard to fix a manifold leak on a 351 ford engine
The best way to fix the engine light in your Land Cruiser is to fix the problem. There are many reasons your check engine light could be on including a loose gas cap and problems with your engine.
Repair the problem.
You fix it by replacing it.
Absolutely not. Once the head gasket is blown, you must not run this engine until the engine is repaired. Coolant in the oil will destroy this engine in short order. Coolant in the crankcase or cylinder is also not a good thing to have because it dilutes the oil and accelerates wear. If enough coolant leaks into a cylinder, it may even "hydrolock" the engine preventing it from turning over when you attempt to start it. And in some cases you can do serious engine damage like a bent rod, by even trying to start a hydrolocked engine. You may also have a cracked head at this time. Until you can fix this engine, drain all the oil and coolant out and park it. DO NOT START THIS ENGINE.
Take it to a mechanic.
