I've had that problem with both my 405 and 404. I usually take off the top and when I put it back on, I put more pressure on top and that usually does the trick.

clean it first gasket then vaseline petrolume and make sure you properly close it as much as possible apply pressure evenly on the top on both sides of the motor cover.proaquatics;2719653; said:

i agree with this attempt the only thing that manufacture suggest is cooking oil like vegetable oil the petroleum suposably stretches seal ring. if this doesn't work try again all my 04 and 05 models do this. i have 03 models still running they were the best IMO
When I had this problem I cured it by doing two things:
Take the top off and turn it over. Carefully remove the gasket, check it thoroughly for cracks or tears. Run your fingers along it feeling for such.
Use some vegetable oil or silicone LUBRICANT applying it sparingly to the entire length of the gasket. Use you fingers and be vigilant.
You will notice that the gasket probably has a "memory". It is holding a certain shape when not on the motor head. Reinstall the gasket "out-of-memory" (lack of better words) errrrr............
I hope you can figure out what I mean. Install it in a way that it will develop a new memory.......errr, i hope this makes sense.
When placing the motor head assembly back atop the canister, use steady even pressure to seat it while clamping it down.
This may have to be repeated a few times, but be careful not to pinch or tear the gasket during this.
It will work! If it doesn't, get a new gasket.
