    what part of GA are you in?
    And I find parts leaking all the time with those encapsulated gaskets under them because some fool over tightened the bolts to the point of deforming the Aluminum casting. Pull it off lay a straight edge on it and it will be warped so badly it might as well have been a stamped part.
    When I am working on something that has a gasket between 2 flat mating surfaces, whenever possible I like to add a grove in the matting surface of the part that is replaceable or if possible make true o ring groves in them, use an o ring of the correct composition for where it is to be used and the likelihood the [art will ever develop a leak is greatly diminished

    yes morons always over tighten stuff thinking they they are helping...they arnt. many gaskets are encapuslated nowdays. some stuff is just sily cone, the factorys use plasama torch to preclean befor applying the silly cone, all robotic. I dont know if humans touch engines any more at the factorys. one think to know, if you have the all rubber gadgets and they are old and not leeking NEVER SNUG THEM UP!!! they will develop a leek in a short time. when ever a human is involved...something is gonna get ****ed up.

    you can fix gaskets , you can fix ugly, you can even fix fat ,but you cant fix stupid. and the sad thing is you dont have to be stupid to do stupid things...well unless you do them a lot.

    Against Stupidity, even the Gods struggle in vain! Not even duct tape can fix stupid. Though it can muffle the noise a bit. I claim to be crazy, not stupid, but there are people who know me well who will argue with that, and I've done enough stupid stuff throughout the past nearly 7 decades that I maybe can't really argue with them.

    Though I do TRY not to be or do stupid.

    A year ago while doing spring service on a mower I discovered that the plastic gas cap had broken. Jacked apart by the threads. Factory replacements were $12 plus shipping.
    Found a file ready made on thingyverse and printed a new cap with PETG for $1.50. It leaked a little when the tank was full and sloshing around so I made a gasket out of TPU.
    Checking it today, the cap and gasket are just like they were when new.
    I also printed a plug cover for the 7 pin trailer plug to keep it clean when not in use. It has been in the sun for about 8 or 9 months and is just fine.
    TPU is also a great product for making dog frisbees as they don't break when the dog bites down too hard. TPU is impressively tough. BTW, my printer is a bottom of the line unit with a bowden tube and it works just fine but it is a little fussy. I print at 240* C

    Good to know! Mine is not bottom of the line, but it is a orphan. Only generic parts available for it, as the manufacturer dropped support shortly after I bought it.

    There was buying the printer, then learning how to use it, then learning how to use the software that runs it. Also the wasted product in test runs or failed prints.
    Some would call all of that a drawback. As in "why not just buy the right part to start with?"
    I just call it fun. And being self-sufficient....
