My friend came over today, and the plan was to change the oil on our Vespas (both LX150s), and I was also changing my belt and rollers. My husband was the shift supervisor (aka, the muscle). Everything seemed to go fine.

She started hers, and it started leaking oil (a lot of oil!). Her filter wasn't on very tight, so we tightened it up. I got mine back together, made sure the oil filter was on snug, and started it up. Mine also started leaking oil! Not a lot, but it was definitely coming out from where the oil filter screws in.

We were very careful with gaskets and o-rights - I thought. I've changed the oil before, and it went fine. But, we clearly did something wrong for them both to have the same problem, but I can't figure it out... any thoughts on how to troubleshoot this?


*the good news is that my transmission sounded amazing!

Possible you left the gasket from the original filter in place?
Either that or loose filter; the metal of the filter body should contact the sealing face of the scooter.

Both of the gaskets definitely came off, and we oiled the new ones before installing.

The mufflers are back on, but we'll take them back off tomorrow to try to figure it out.

Is it ok to loosen the filter (or remove it) to check the gasket and retighten it?

Yes, you can remove and reinstall the filter. Make sure the o-ring is squarely seated in the filter.

Oil leaking
Just remember to have an oil pan under the filter when you loosen or remove the filter...saves quite a mess!
