I have no idea about the valve. But the pan itself isn't tough . Make sure you have the bolts or studs for it. As far as the gasket , check out boe the have one that is super simple and $25 . After you get the under tray and all that down it's not that tough just take time and patience . Make sure you have a tool to remove the current gasket, but after doing it myself ( granted not that pan , but a moroso ) I wouldn't pay to have it done . YMMV
Good call on upgrading the pan, lots of people forget that when you pull one G in a corner, the surface of the oil in the pan is pulled to a 45-degree angle since many Lotus cars can pull more than one G...you get the picture.
is right, doing the pan, even for a novice, is a pretty easy upgrade, just take your time and follow the directions, if you have everything lined up ahead of time it's an easy one-day mod (maybe two days if you take your time).
