Most likely your head gasket failed and left for too long which caused the heads to warp and need to be resurfaced to put on a new gasket.
Remove intake and exhaust manifold. Remove head and replace the gasket. This is a major repair best left to a professional.
I would be more worried about the length of time that a head gasket has been left on your Jimmy. I take the gasket off my Jimmy right after I'm done using it. 16 years is a long time.
Gaskets that have an "UP" are marked with a stamp saying UP - LEFT - RIGHT. If there is no stamp, there is no "UP" on the gasket
behind the left head between the motor and the fire wall. behind the left head between the motor and the fire wall.
I think you mean head "gasket" - not casket. This is the gasket that is placed between the engine block (bottom part of the engine) and the cylinder head. Your Disco has two heads, so two head gaskets, a left one and a right one.
If it is running out between the block and the head, you probably blew a head gasket. If that is the case, be sure and have the cylinder head resurfaced before you re-install it after you change out the gasket. A blown head gasket is usually caused by warpage of the head when it overheats. TIP: as long as the head is going to be resurfaced, you might also get the valves reground.
no as long as you are sure which side/head is leaking
Extremely difficult as this is a major repair. Best left to a professional.
what about pressure testing? is the residue left over from the gasket failure? remove the thermostat and flush the system a few times, (use a jet wash if available and back flush it) what about pressure testing? is the residue left over from the gasket failure? remove the thermostat and flush the system a few times, (use a jet wash if available and back flush it)
