Subject: Re: Severe Oil leak
Realised I have the original cranshaft here in a box...just checked, & there is a return scroll. Removing the sump...have fun! You will undo a squillion nuts & bolts, heave away a large aluminium casting, peer up in wonder, to see...nothing. Well nothing apart from more aluminium & the gauze suction filter for the oil pick up. The actual sump is the next level up...I think I figured the engine needed to be out to remove that. Bentley/Tresilian's little joke, perhaps.
A book with exploded diagrams/pictures even, of the entire engine, would be great, but there isn't one. The original handbook is fairly detailed, the club sell a V12 manual that is pretty helpful, but short on pictures. Apart from that, there is the "Motor Trader" service sheets, which are pretty detailed & shows some fresh pictures not in the handbook.
Incidentally, if you're rebuilding the engine & sleeving back to standard, I have a new set of pistons spare. They are to 8.25:1 compression ratio, but of course could be machined to a lower figure if preferred. They are exactly as the original Lagonda pistons, other than the higher compression land. My rebuilder said every V12 block he'd worked on had proved to be porous, hence the original plan was to sleeve, and I had these made in advance...but testing showed mine was the exception which proved the rule, so it ended up being bored to + 60 thou, with another set of pistons being used.
PM me if they're of interest.
