The volume of liquid in the pan would indicate the "Leak" would have to be low. Has this block previously been sleeved?

Well, I pulled the plugs and it doesn't budge. Not looking good. I guess I am going to weigh the options: rebuild it or get a crate motor.Chas

Bear with me; I'll get to the point.
As a hunter, I learned a lot about anatomy. I realize it doesn't qualify me to be a surgeon. However when something meets a violent end, you do not have to be a coroner to figure out the cause, either.
Engines are the same. It doesn't take huge skills to pull it apart. If it died violently, it will be obvious. It takes a surgeon (builder) to put them back together, with the expectation it will be improved and live long.
So yes, tear it down and entertain us.

I will work on it this week in the evening and let everyone know or see how it looks. Olddog you are right about taking it apart, just don't look for me to put it back together.

Try to preserve evidence, as you take it apart. We are especially interested in the intake gasket and the head gaskets.
With a modern day digital camera, pictures are practically free to take and store. Get several pictures at each step of every part, before you take it out.
Secondly try to keep track of where everything came from. It's easier when you have a large bench, so you can lay out all the pieces like an advertisement of a rotating assembly is pictured. A permanent marker can be used especially for pistons. This could come in handy if it is rebuild-able or parts are re-usable, for they guy who assembles it. Bolts in cans or zipper bags with a label.
Make sure you do not mix up main caps. Each rod cap fits that particular rod. It's best to mark them before you remove them. They are likely already marked, if so you do not need to mark them again, just understand the marking convention used.

Well, I worked on it tonight and got one head off, the passenger side one. There was some oil in the valley where the lifters are. I tugged on all the lifters and they looked ok. When I removed the passenger side valve cover there were traces of frothy oil. At the front of the passenger head there were 2 slivers of metal and I looked around and could not find where they came from. The rocker arms looked fine, the tops of the valves looked ok. There was no more than a couple of teaspoons of water in the 4 cylinders that are visible. Tomorrow, I will work on the other head and see what is happening there. Olddog, I guess you and I were posting at the same time. I have marked everything and put all the nuts and bolts in baggies marked where they came from. I will decide where to go after I get the other head off. I am limited on how much I can work under the car because of vertigo.

Tonight was frustrating. I can't get two of the head bolts out. I am rounding them off. Tomorrow I will see if I can get the oil pan off and see what I can see. |

Wow! can't get the heads bolts out. stripping the head of the bolts? Do you have alum heads? Sounds like we have a problem Houston! I hope you find the engine isn't totally gone. Keep up informed. I'll be praying for you as this can be a real expense you most likely didn't need with the holidays coming. |

Youth is a wonderful thing. One of the young Turks from work went home at lunch time and was able to get the bolts loose. I will finish taking them out tonight when I finish at work. I will post any news then. I looked at the intake manifold gasket and it looks like the part of the gasket for the forward water port was blown out so this could be what started this thing.

Well mystery solved. The intake manifold gasket leaked into the front drivers side cylinder and now the piston is tilted 5-10 degrees and I can see the wall of the next cylinder. I guess I need to see what my options are and then proceed. One bright side we are going into winter so I have time to think about it. Chas

Are you up to posting a couple of pics of that unfortunate mess?  |

Damn the Bad Luck. Maybe this will end up a positive with bigger and better HP.

Dang. I nearly called that one - and did not really want to be correct. Here's to hoping you get it back together - at least you have a few monthes before the springtime. This stuff normally happens in June....

Thanks. It certainly looks bad, but maybe it's not as bad as it looks?  |

I have a 428 that nearly did the same thing, I was using Failpro gaskets just like Chas, I had a oil leak at the intake and took it off to reseal and notice the blue silicone slowly working its way into the intake port, I replaced with standard gaskets to fix the problem. Since then I have seen it on 3 other cobra's, all small blocks. If you do a search on Failpro intake gasket you will see it is quite common, my advice is to change soon or you will get a hydrostatic lock and bend rods or break other things.
Sorry for the problem, but you will overcome and it will be better.
