I'm not sure if this is the right place, but...
I'm helping some friends rebuild a 1984 Nissan Z24 4-cyl. This is the first engine they have done before, and the first Nissan I have done.
They are building it in free time, and I'm there to work on it when I have my free time. But, times don't always over-lap.
Unfortunentally, they decided to put the pistons in while I was away. I showed them how to ring them correctly, but they pounded them in after I left.
When I got back, I paid no mind and put the head on. Since then, the motor has been all but entirely short-blocked.
I went to adjust the valves (new cam also) and put cyl 1 to TDC. They asked why I was starting with 4 at TDC...
Huh?
Yup. They put the pistons in bassackwards.
From front 4-3-2-1 instead of 1-2-3-4. All of their bearing caps and everything are on the correct rods, but each slug is in the wrong spot..
So, Do we tear down the entire block again to fix it, or should this be alright?
