I just did the first oil change on my rebuilt L28E. It's a stock block with an N42 head, schnieder street cam. The car started leaking oil at the filter the first time I took it out, the seal on the oil filter wasn't flat so I figured it was a defective filter. Put on another one in the garage, spewed oil everywhere. Put on another one, from autozone, reccomended size, the surface was clean. No the old seal was not there. Yes I put a little oil on the seal. Yes I tightened it enough. Drove it again.... same problem. Not only did I miss my exams but when I fired it up it was so low on oil that the engine was literally griding metal and moaning until the oil I added circulated.
Am I using the wrong size filter?
The ones I got from autozone were FRAM Tough Gaurd TG8A
