Hi to everyone,

I recently got a '42 Lincoln Zepher V12 in a buy it all sort of deal. The engine was all taken apart. Upon a little cleanup I soon discovered why it was included so cheaply. It sure appears that there is a crack on the engine block pan rail on the passenger side of the engine. My first question would be, can these type of problems be repaired, or should I be looking for another block?

Also, is there a listing somewhere of engine specs, like main and rod crankshaft journal sizes? And, how can i be sure that the block i actually have is a 1942 V12 block? There were some numbers/letters on the back of the block, but I forgot to write them down when at the shop.

Thanks,

Mike

Your '42 block will have a bore of 2-15/16" plus any over bore. The longitudinal crack on the inside of the lower crackcase (between number 2 and number 3 main bearing) may be fixable If it doesn't extend into the main bearing webs. There's a process called "stitching" or "pinning" that closes the crack and keeps the casting from moving. I sucessfully fixed a '42 block with this type of crack and followed up with a block sealer. I will see if I can dig up some before and after pics. Here they are.

As Dee said, the stitching process is one method and when it is finished, it would be as good as new. I recently watched a video of the process and it is interesting to say the least. Either look at Fordbarn.com and do a search there or possible you may find something about it on YouTube. But the process looks to be pretty straight forward and as long as you follow the directions, it should do the trick.

Another way to repair it is if you have a good welder with an oven big enough to put this block in. The block will require being heated, then removed from the oven and tig welded. This has its advantages , however according to the stitch process people it could cause another crack. Who knows for sure...I sure don't.

Type in Locknstitch.com go to their web site and read or watch the repair video. It's a neat process for sure.

Guys,

Thanks for the replys. The crack on my paticular block is more visible right on top of the oil pain rails on the block, not so much on the inside. Well, as far as my tired old eyes can see. Anyway, you can see the crack running lengthwise from the freeze plugs/casting core holes or what ever they are actually called. Unfortunately, I will not be able to get a good picture till Tuesday as business has me on the road Monday. So I will post a pic then to show the problem.

Thanks,

Mike

Mike, my block also had a crack on the pan rail (opposite side) that was fixed. Had to give up one pan bolt threaded hole but no problem.
