It stopped raining just long enough to get the 4.0 oil filter adapter off to change the "O" rings. The ones in the whole engine kit were the wrong size and I just now got the right ones after the block was already in. Now the only way to get at the adapter bolt is to get a T-60 TORX socket, bang out the 12mm bit, and use a 12mm wrench on it. I used a 12mm crowfoot flare wrench with a 3/8" breaker bar and a cheater pipe to break it loose. Then I put a 12mm ratcheting box end on it to unscrew it the rest of the way. Getting the adapter bolt back in to the adapter with the new rings is difficult. Since the oil filter has the same threads as the block I just screwed the adapter to the filter which drew the bolt and rings right in. Maybe it will dry up enough to get it back on tomorrow.
