ok now I have a coolant leak. I checked ALL hoses throttle body heater is new, reservoir is new. It appears that the leak is coming from the rear of the motor. I am stumped and about ready to scrap this thing.

I also have an exhaust leak that seems to be coming from the same place which I can hear under load but that is it. Sent it to an exhaust shop and they could not find it either. WHen I"m driving it is coming from the right side of the motor. I was thinking it was a manifold gasket, but now i don't know. WTF.

Thanks again,

If you haven't done head gaskets I would start there... Mine was leaking coolant externally and was a bitch to find (cylinder 5). Your engine is more or less at that point where head gaskets start to fail. It could also be the source of your exhaust leak. Good luck.

 

For the exhaust leak - look for white or black soot marks. My exhaust leak had me stumped for a while. I replaced (both passenger's/driver's) exhaust manifold gaskets and manifold to downpipe gaskets. Still had the leak. Turns out my Y-pipe had a crack at the flange where it bolts to the manifold. I removed the y-pipe and dropped a bead around the flange.

Also check your exhaust manifolds for cracks.

Or Scrap it, we need a few more D2's to be parted out.

 

I,m just south of you I could use the parts.
No; I think you need to borrow a preasure tester and test your system at 20 pound for 30-minutes, you will find the leak.
Fill and purge the system first then test it, you will be surprise how easy it is to find a leak on a cold motor at 20 psi.

 

Coolant leak and exhaust leak from the same area...blown head gasket.

 

Is there a place I can get all the upper gaskets in a kit? I CAN NOT let this devil get me. Its still got a lot of value in it!

 

If only there was a place on the internet that sold everything you could ever need for your Land Rover.

Thanks, I just came across this! Not that I want to cut corners, but can I get away with using my head bolts? do I NEED to put in new ones?

 

YES, you need to replace the headbolts. The bolts are torque-to-yield and are NOT reuseable. To achieve the right torque, the bolts are designed to stretch as they get tightened. Once tightened and stretched, if loosened, they will not retract to the original size, and hence no accurate way to get them to the correct torque.
