Cylinder 5:

 

that would be bad, Yes

 

How hard is putting a different engine in?

lol oh boy...wife not gonna be pleased

 

"How hard is putting a different engine in?"
it’s all relative to what your experience is.

If you have never done it before it can be intimidating, once you have done one or two its just another days work.
Take lots of picture so you can refure back to them, label and bag everything when you take it off makes easier.

easlily do it in a weekend with a friend and not to many beers or blunts

 

For us newbies, can you please explain what's wrong and why? I see cylinder 5 looks totally different, what's the cause? Thanks

 

There is no coolant passage next to that cylinder.

Hence, the only way for it to have been cleaned by coolant is a leak through the block.

 

Im thinking of putting it back together and running Moroso or Irontite ceramic block seal through it. I figure its meant for hot-rod engines, doesnt clog the cooling system and will buy me some time at the very least.

Is this a stupid idea?

 

you can try anything you dont have much to lose at this point. did you have that head preasure tested
caymandrew there is no water running bewteen the head and the block in that area. So if the one piston is "steam cleaned" it meens that there is a crack behind the liner, and the coolant is entering the combustion chamber which is what causes the steam cleaning effect.

 

Block seal first and then after it has had a chance to work change to a 180f stat may keep it running while you plan the next step. Any motor from boneyard will likely need HG work. "Discovery" and "disposable" and "depressed" are all "D" words.

 

drow: didnt have it pressure tested. Just got the head off this morning. Would would that tell us anything we dont already assume? HG looked fine and pretty nice actually.

Buzz: thats not comforting haha

So, re-assembling...

At this point I only have the drivers side head off and its gasket has no sign of fault.

The passenger head has no misfire codes.

Do I still need to get the heads checked for flatness?
