Outstanding,

I like to watch the circulation thru' plug, tells me the waterpump's working


luck,greg

 

Yes....But I still hear air in the heater core. Should I let the vehicle sit overnight with the funnel full of coolant with the vehicle off to purge the air? I just do not understand why this air is still in the system. I see very few bubbles coming out now, just very very small occasionally which could be from the seal on the funnel itself. I do see coolant flow and did see some corrosion on the radiator which has been rodded out before and recently back flused. My damn brake light switch went out while working on it too. Lucky me as it is stuck in park and I had to jump the switch via the instructions on Atlantic British website to get it out to the way to get to my ford which is apparently not a fix or repair daily.

 

Pressure tested again. Steady stream of coolant leaking down front of transmission/rear of engine. I see coolant in the back of the valley pan puddled up. I am guessing this is a valley pan leak?

 

what year is your Disco? VERY common leak point is the uppermost left corner (vhicle orientation) of cooling fins. Pull the shroud off and take a look up there...

I've had TWO rads on my '95 leak in that exact same spot.

 

It's entirely possible

If you go after it, and it looks good, you're halfway to headgaskets, do it right and you'll probably never do it again. (on this truck)

luck,greg

 

Valley pan gasket is off. Encap plastic pieces were deteriorated and cracked. Where do I need to put the rtv black silicone? Just on the endcaps on the block side or all around the holes on both sides of the gasket? Truck is a 1998.

 

Got the 98 DI put back together. Here are some pics of the tear down. Radiator was also clogged and was rodded out at radiator shop. It appears the coolant passages at the rear of the engine dont flow into the intake manifold as it is "blanked off" on the intake. This is probably were it was leaking due to the excessive pressures and markings seen on the gasket. I didn't have to remove the "ram" portion of the intake as Rave instructed me to do. I removed the bolts, but the seal was so good, I didn't want to mess with it. I didn't have to remove the valve cover to get the intake on, just loosened it up....I did end up removing the valve cover to reseal gasket. Watch out for those washers as they are actually in the valve cover gasket holes and will fall off when you remove the gasket!
