Well as some may know, my 2.3 massively spun the rear main bearing. Even though I have not opened the case, the debris in the oil tell me that the crank and likely the case is gone.
I think I can reuse the heads and pistons and cylinders. But I am assuming all of the other internals are toast. Pulled the oil pump and filter and there was no visible metal in these but there had to be parts of that bearing coming off for a while before it failed. Any thoughts on trying to reuse crank, cam, and case? Or should I just start building from another case? This engine had 98 mm P/Cs on it. I thought I recalled that the largest P/Cs that could be fitted were 96mm without opening the case. |

Do you know where your new 78mm crank from the Type IV Store is made?
If China, did it receive the same treatment that Jake Raby is talking about in the post referred below since he doesn't own the store anymore? Is there something special about the current Type IV Store crank vs the ones sold by Aircooled.net or EMW, or are they from the same source? post from 2016: http://www.914world.com/bbs2/index.php?s=&...t&p=2206685 |

But I will ask. But regardless of what they have or have not done, anytime you do a build you still have to check to make sure all parts meet specifications. I spent a couple of hours doing my initial check of the parts received. When I take them to the machine shop to be balanced I will have them check again. Some adjustments may be necessary, but I don't think there will be major issues. |
