Title describes it, but I'll elaborate. I doubt it matters, but the 340 is stroked to 416. The headers are from TTI, and took a lot of finesse to get installed, but are full length headers, no fenderwell nonsense, etc. Something I've always wanted... But necessitate a remote oil filter... There just is no room. (note, I'm hoping to find someone else that's gone thru my nightmare here, with a good outcome). Moroso remote oil filter block adapter, and some other remote oil filter mount. -12an lines and fittings. Somewhere on the block side I have an oil leak... and as y'all know, oil goes everywhere, so it's very hard to find where exactly it is. As the motor is freshly rebuilt/stroked/etc, all gaskets are new, etc, etc. Barring a rear main seal, which I think is unlikely at this time, it seems to me the likely culprit is this remote adapter. Thoughts? Better remote adapter or other oiling solution? I'm all ears here. I just want to get the small leak (which of course makes a big mess) buttoned up. Thanks all.
