Finished reassembly last night after blowing up the heads on my Disco. Went to fill it with coolant (yes, I added Glycol this time). It immediately began pouring out of the block on the passenger side, where the front cover meets the block.
It appears as though there is a crack starting at one of the water pump mounting bolts, extending beyond the front cover-yet no water in oil, or vice versa. Disassembly begins this evening. If the dye penetrant dance proves the block is cracked, I will pull the block and try to TIG the waterjacket shut.
Thank the Gods of Solihull I work in a factory with a friendly toolmaker and a hell of a welder!
Please, wish me luck. I'm not sure how Merry Christmas is gonna be. I knew I should have bought a new block "While I was in there".
Peace,
Paul |

Impressive how fast you got the heads back. How bad was the damage afterall to the heads? |

Michael:
The heads were back last week. Cost was only $212 for valve job, install and ream two exhaust valve guides, and resurface. Turnaround time 72 hours.
Two exhaust valve guides fell out of their bores, and both heads were moderately warped.
I was really frustrated over how long it has taken me to get it back together, but "all good things in all good time".
Peace,

Paul,
start over?
when do you say when?
what happens when its all back togather and it leaks from another corner that the water level has yet to reach?
I hate to be the devils advocate here, because I know your feeling it...i'v been there with motors and its the worst fucking feeling in the world it makes me want to work round the clock till that motor wins INDY!
but in reality i would have been better off with a really good deal on a new start from someone elses misfortune...yes paul I'm talking the bone yard here...sell the heads they are worth 250 on ebay you'll get it in a week. find a low mileage from a crash and throw it in lock stock and barrel.
I truley am feeling your pain man

I got my 455 all back into my firebird all the accesories back on that tangled mess fired it up and relized I forgot the little o-ring between the intake manifold and the water pump.
2 more days to get the manifold off and back on,a lesson learned at 15 |

Musky:
The worst part is I can have a mildly used shortblock in about an hour...
I'll tear it down to the front of the block this evening to see just what the damage is. I am hoping against reason that it is just the water pump as I have not only a spare pump, but an extra gasket... If not, well, I know what I'm getting for Christmas and it ain't likely to be the Christmas goose from the wife!
Peter:
I once assembled a small-block for my race car. As I was bolting the oil pan on, my dad walked up and asked me how well I expected it to run with only seven pistons. There was a rod/piston assembly lying on the floor next to the engine! After hurriedly turning the block over, I realized it was from another engine I'd torn down to get parts forthe one I was reassembling. Surprising I didn't have my first heart attack then.
Updates tomorrow... Unless the kid has done something stupid again and I have to spend the entire evening keeping his mother from letting me kill him-He crashed his car Tuesday so when the Disco is done, I have yet another non-paying family member's car to work on.
Peace,
Paul |

Man, I feel your bloody knuckles. About nine years ago I rebuilt the engine in my '79 Bronco. Bolted everything together and forgot to line up the stator shaft and that other shaft around it. In other words...it wasn't right. Cracked the bell housing trying to seat it all, and fried the starter trying to get it to work. Once I realized what I had done I pulled it apart and tried to pull the stator. I do not know anything about transmissions. Ended up with all of the parts at the front of the ••••••••••• on the floor with about 9 quarts of ATF. Had to pull the trammy, and have it all put back together at a shop.
In the end I ended up with a great engine. I thought I was being cool putting on Cleveland heads on a Windsor block. This raised the compression to somthing awful as the combustion chamber is much smaller on the Cleveland. Truck ran like a bat out of hell, but I got bad knocking on Super Unleaded, and to get rid of it I had to run AvGas at like 110 octane. Only Bronco I had ever seen that would do 120 MPH relatively stock except for the heads 
Good luck, but I hope this gives you a little smile in your agony.

Paul,
I was waiting in the pits at Riverside Raceway when the driver came in with the car in tow and asked, "did you tie the distributor in a knot". I had let him put the rotor and cap back on the car, an old Alfa, and he forgot to tighten the rotor set screw. It dropped into the advance weights, jambed and spun the distributor. From that day forward I've always checked everything twice. There is only so much agony you can survive in one life. Good luck and I hope you have a bad pump and don't have to replace the block, though haven't you always wanted a 4.6? |

I take it your motor overheated badly...it'll probably never run right again. These aluminum motors don't tolerate overheating -- this may be a good time to stop flogging a dead horse and a good excuse to put in a 4.6.
After the little woman ran my 3.9 out of oil and overheated it a couple of times, it developed a ticking sound that continued to get worse as time went on. I had the lower end done and thought we'd fixed all the problems. The first time I started it up, that damned ticking started after the motor warmed up. I then had the motor COMPLETELY torn down and rebuilt -- wouldn't you know it, the minute we started her up, that damn ticking sound started again.
At that point, I gave up and put in a new 4.6. Best thing I've ever done to my truck.
