In trying to stop an oil leak at the canister on my 292, I decided to install a screw on type adapter. After removing the original can, I got a DC kit. This kit requires removing the threaded fitting out of the block and using their threaded fitting which has a 3/4 nipple on the outer side for the spin on filter to spin onto. This resulted in a good size leak. Next, I tried a kit made by Wix. This kit leaves the original threaded adapter in the block, using their threaded adapter, which is 3/4" threads on both ends to hold the plate on. Even bigger leak with this setup. I tried to reinstall the canister back on and it leaks way more than it did to start with! I noticed that the plates from both kits had the word "top" notated on them. The DC plate had an oval hole at about the 4:30 position to correspond with a hole in the block. The Wix kit had 3x 1/4" holes in about the 11to 1 o'clock position. I cleaned the block with brake clean and lightly glued the gasket to the block, making sure the gasket was below the hole at 4:30position in the block on solid machined surface.I used no sealer of any kind. Should there be some sort of plate at the block even under the canister system, as mine had none. Also, if so, would the Wix plate just piggy back on top of an existing plate? Any help would surely be appreciated, thanks.
