power loss - Land Rovers Only

discodad · 06-11-2007, 02:13 PM

1996 disco se7. Recently had engine overheat due to leaky thermostat housing which I did not tighten enough. Engine ran in red zone for approximately 2-3 minutes and then was parked. Next day , engine starts idles ok, but power loss when reving engine. some sputtering, cuts out and returns to idle. I am wondering if I melted the cat or is there a problem with fuel, ignition coil or some other reason. ANy input would be helpful.
Car history 96 disco 120K, replaced head gasket, transmission, water pump, too many little things to mention.

You allowed it too stay in the red zone longer then you should, and it shouldn't have been shut down, but allowed to idle with the heater on full hot till the engine could desipate most of the heat. I would suggest you do a pressure test to the coolant system, maybe a chemical block test to make sure your have no exhaust in the coolant system.
I would spend some time looking at this without driving it any further till you know there hasn't been any head or sleeve damage.
