283 Spin-on oil Filter adapter Problems

Hello All
Thanks for the helpfull advice over the years I've gotten for my '56 wagon and '64 Impala; I try to write the questions completely to be helpfull for the advisers and users . That did'nt always work, due to mostly being tired, sleepy, and not being a mechanical type, but some one like you guys who loves classic cars so this is a belated apology.sorry.

I had to have a new mechanic put a rebuilt 283 long block(casting # 3789935 Mortec.com says '61-64) in the '64 replacing a 350. It did'nt have any oil filter setup so the mechanic wanted to to put on a spin on adapter kit rather than take the boss off the 350 adviser silicon 12 mentioned.
After 3 months of taking the car back to the shop for other problems and after only 900 miles on the new engine I was forced (by traffic) to drive over a driveway that had some concrete pushed up by a tree root. There was some scraping so I when I checked it out a half -mile away I saw there was a small oil leak; I slowly went back another mile to my place. I had lost only a half-quart of oil. I saw that the leak was from the the oil filter adapter area even though this is up much higher than the oil pan and the oil pan was not hit. It looks like the impact force caused the oil filter adapter to go out of whack. (The oil filter was still screwed in tight.) I had no oil leaks before.

My new mechanic had to temporarily move due to lease and labor problems so I drove it a couple miles to my regular mechanic (who's been in business 25 years). Unfortunately after trying a couple different adapters, using the gasket the comes with the oil filter that goes with the OEM canister filter he was unable to get the adapters to work or explain why not. Actually since it was leaking worse I had to tow it back to my place.

1. Does anybody have an idea what happened with the leak and why the other adapters did'nt work?
2. I had a mechanic say a remote adapter canister oil filter attached upright to the engine (like my '56 chev 235) or the inner fender could work. Is the 0EM canister filter better than that; I hear it's pretty messy? what do you think?
3. As for the boss for a 350 working, a parts guy at a Chevy dealership said he thought openings for a 350 and a '63-64 283 were different.

Thanks

I'd have to crawl under it to see what's going on. More than likely the first adapter cracked from the oil filter hitting the concrete. You need to take the adapter off and clean it up best as possible and look for cracks in the block. Could it possibly have an old gasket stuck to it? Sometimes that are hard to see and they get left it.

I've used the canisters when I had to, but nothing beats a spin on filter. You may have to find an old time type of shop that is better equipped to help you, maybe you have a hotrod shop close by?
