Help, Another Oil Pan Leak Thread

I had that exact problem after I had my block line honed.
It had run well in the first season; but I had figured out that the decks had been machined ridiculously off square both side to side and end to end. So winter came and out popped the engine
Turns out that after the line-hone, the factory 360 seal was no longer even touching the crank on one side, while the other side was smooshed onto the crank. I saw that after I replaced it, chalking it up to a faulty install on my part, and sure enough the second seal leaked almost right away. That's when I went back to have a better look at the removed seal,and thought about it. I went straight back to the machine shop, which denied culpability.
But said the manager, if I brought them another block they would line-hone it for free. Yippee!
What about the boring,honing, and decking. I mean the whole reason it's here is cuz you said the bores were crooked. and I brought it to you cuz I knew the decks were not square and you said you couldn't square it until you line-honed it.
Well no that would be extra, cuz that part of the job was done right.
Wait what? you want me to pay for your mistake, and I should still supply another block for you to practice on. I don't think so.
Well that's the best I can do, said he.
Best daymn machine shop in townmyazz, muttered I.

So I took my leaker home and stuffed a rope seal in there, and the fix would have to be good-enough for me. It still seeps a bit. That was 2004.

Not saying this is your problem, but inspect your previously-installed seals for the tell tales. I guess also make sure they were not installed backwards,lol.
