Vent and drain plug different

[stratodown]

I have an '88 J200STLCCM (200 looper). I just changed the LU lube and after I had both the vent and drain plugs out, I noticed they weren't exactly the same. One screw has a flat seat and one has a grooved seat. I can't tell by looking at the parts book which one goes where. Any ideas? I'm also guessing that the gasket/o-ring each one takes is different. Is that correct?

Some are designed to use a flat gasket, and others are designed to use an o-ring. They are not normally mixed on the same motor, but there is no reason they can't be. That usually happens when one of them has been damaged and replaced. Both will work just fine as long as you have the matching seal.

If one has a magnet on it, make it the bottom plug.
