    Thanks,I've got another exhaust manifold coming but would a cracked exhaust manifold cause an intake leak? When I get it I'll have it machined down flat.

    If the int and exh manifolds are 1 piece, or even bolted together, and the exh. is warped it could possibly hold the intake away from the block.

    Yes it came out of the car with the engine attached. Has some cracks in it so welding is an option but prefer not to. Since this is a restoration. It is a very late 57 year car. So may have 58 parts. 

    That number is a late'58 number. I will post the interchange for that number in a while. Some thing is not correct. That bell does not belong in that car. Is it an air cooled or water cooled transmission??

     

  3. Be careful on setting timing, the vac. chamber retards the timing unlike most cars where it advances it. So, at idle with full vac. the timing will be late. Also be sure you are running metal core plug wires.

    As an engineer, I'm curious to understand how wedging a pin into a crack pulls it together.

    I have 2, 3/4" thick pieces of steel with 1, 3/8" diameter x 5/8" long pin inserted in the joint. I have had a man beat it off of his trailer and it has not come apart!!

  5. I do not know what experience the other people have. I have welded aluminum castings, and we have done a lot of metal stitching. The pins we generally use are made to actually pull the crack together.  It is your decision. I just put in my 2 cents, and it apparently was only worth 1 cent.

    Hmm seems to be a lot of controversy, Pinning seemed like the safer way to go but I was also worried that if the pins dont hold then we just weakened the crack further, as mentioned in my original post I have only heard of this technique recently.

     

    Welding seems like the more permanent solution but I am worried about the heat. Does anyone know if it would be affective to stuff a wet rag or bag of ice in the cylinders while welding the aluminum to help keep them from warping? or would they just be more prone to warping because of the large temperature difference?

     

    I'd also like to take the time to thank everyone for helping me out with this. Of all the forums I have posted on this is the only community that has helped support me rather than come up with clever ways to tell me my block is junk.

     

  7. We are located in north east Pa. and could possibly do the cold repair with aluminum pins. Tig welding requires a lot of heat. Normally on something that size, the whole block would have to be preheated, and you do not know what impurities might be pulled out in the welding process possibly causing a disaster.

    those are some big hit n miss on there or is one steam ?

    The 1 up front is a 94hp. 2 cyl. Blackstone Diesel. The only one in the USA. In the rear are 2 35 hp. Superiors side by side. The Blackstone is about16K lbs. and the superiors about 8K-9K each. Oh and there is a little 4 or 5 hp on the upper deck.
