I did another oil change on the Onan 2500LP this morning, what a pain! I'd always had some oil drip on the bottom pan and run out in other places, but today was a total mess! The design on the pan under the engine includes a 1/4" lip around the access hole for the engine oil drain plug, which helps send oil all over the place, not down into the drain pan as desired. To exacerbate the problem, the access hole is not centered on the drain plug making access difficult and re-threading the drain plug even harder. Dropping the plug into the bottom pan full of oil and then trying to retrieve that slippery brass (non magnetic) plug was not fun.
I'm looking at replacing the drain plug with a Fumoto Engine Oil Drain Valve, but with the offset access hole, I'm wanting to know if someone has already gone this route. It looks like I'll need a 5/8" long 1/4 NPT close nipple to drop the valve down to install it, but if someone has already figured this out, please post up.
Here's the link to the Fumoto website, trying to decide if I'll need the F107N, F107S or F107SX.
