Disco II - Blown head gasket
According to my mechanic, there is no way to determine if the block (not head) is warped without taking the block out and sending it to someone to have it checked. Also, not much difference in cost and that point. Last gasket job in 2008 cost $2,900. I was surprised that the block could warp. Is that BS?
Hope this helps

I've never worked on head gaskets myself, but this all has me a little confused.
It seems as a first step before deciding to replace the block, you'd have to take off the heads. If you see there's a clear failure of the head gasket, then that could be your culprit and you just replace the gaskets. If there's a crack in the block, then you're likely looking at a new engine. If the heads are warped, you'll have to get them machined. I've never heard of a Disco block being warped—it's not aluminum, right?
This is based on what I've heard/read, though. So don't take it as gospel. I just don't get why you'd think about replacing the whole engine before taking off the heads.

yes; remove the heads and hope for an obvious problem with the head gasket.
the heads should be milled no matter what.
disco block is aluminum and like two hot pieces of anything bolted together that are heated and cooled they will wrap.
because you can do head gaskets for under $400 and a used engine is $1500 and rebuilt are $5k
next step is up to you

Well, happy to report that it was just a blown gasket after all. After trading a few text's with MLN01, in which he recommended a few local shops, I decided to let the professionals take a look. The mechanic at the recommended shop tested the heads and they were fine, no warping on those nor the block. I guess the last time I had the HG done, the shop didn't mill too much off. Total bill $2,164 (located in Charlotte NC). Had them grease up my driveshaft and suspension fittings while there were at it, but happy to report its back on the road and they said she drives beautifully.
Thank you for all of the feedback and suggestions.
Sincerely,
