Subject: Re: Severe Oil leak
Hi,
I believe the original "seal" was simply a return scroll..I know my engine has been rebuilt with a conversion to a normal oil seal...unfortunately I don't have details, but I recall the rebuilder saying the scroll return wasn't satisfactory. Scroll return threads were a common alternative to crankshaft seals.
You possibly have two separate issues here. One is that it is likely your engine has been overfilled with oil. Check the level gauge...but it might be that the float has sunk or is sticking. Easy enough to drain the oil & check the quantity. Hopefully that is all that is wrong. Other problems could be a blockage to the drain from the return scroll, perhaps also worn bores/broken rings pressurising the crankcase...but not in isolation...mine used to burn & blow out oil in prodigios quantities, but not from the rear of the crankshaft.
