OIL BYPASS CAP
The oil bypass cap that seals the oil pressure relief valve housing on the engine's bottom end.
70-4192 is the oil bypass cap, part of the oil pump and release valve and manifold assembly on the engine's bottom end. It caps off the oil pressure relief valve housing, the part that bleeds off excess oil pressure once the system builds past what the engine needs.

The legacy form of this number is E4192, so if your parts book or an old parts bag shows that stamp, it's the same physical piece as 70-4192. Our catalog record for this one only shows a single appearance, tied to 1964, so we don't have a wide spread of model years to point to beyond that.
If you're chasing an oil leak or rebuilding the release valve area, this cap and its sealing surface are worth a look, but call the shop first so we can confirm it matches what's on your engine before you order.
