    BV350 freeze plug disappears?

    I have been having some coolant issues and reading various forums I thought I might be having some faulty clamp issues. When I add water now it pours out a hole in the bottom of the engine, right below the spark plug. Looking up with a flexy camera I can see a hole with rustyness going on inside it. I am assuming the freeze plug came out or rotted away...there is a ton of rust in the hole. AF1 sells a replacement freeze plug which is metric thread and tapered. I do believe this is not actually called a freeze plug but excuse my use of the term. The muffler mount closeby shows signs of rust making me guess it has been leaking for some time. Any ideas of getting the old one out and new one in? I cannot register at modern vespa to post there...their robot tester is out of date.\

    Still have not fixed speedometer on my Scarry 200. Sold my Honda Ruckus, Scary 250 (neat scooter), and my Sportcity 250 (least favorite of all scooters)

    beginning to think I may have a very heavy paperweight here. I cannot seem to get the Piaggio folks to tell we what to do about this problem. They mostly ignore me. One dealer said he would sell me a head for $350. I just wanna plug the hole and get back to riding it. Changing my Piaggio BV350 recommendation to DO NOT BUY. Here is a picture of the hole..looking from ground up.

    Why don't you send that pic directly to AF1 and see what they say?

    i did that - been chatting with Steve..not much help
    I will keep banging it around until someone coughs up some info.
    I was dreaming last night about having one of my welders weld it up.

    Sounds like you're f*%ked. Why not buy the tapered plug you mentioned and see if it fits. I know, still not much help.

    Looks like a plug for the water jacket that was pressed in after boring a passage. Should last the life of the engine if the 2 year coolant flushes were adhered to religiously using a good quality mixed metal coolant and distilled water. They usually only rot out once the corrosion inhibitors in the coolant have failed, wrong coolant was used or people have used tap water to top off the system.

    Pull it with a slide hammer if you can (you may need to cautiously drill it out being sure to use a depth stop so you do not go too deep), clean it up and either get a new generic press/hammer in plug that matches the dimensions or tap it with a tapered pipe tap and put a tapered threaded pipe fitting plug in it.

    With a pressed/hammered in plug be sure to get things surgically clean and smooth without reaming it out to an in-between size or it won't seal.

    Go gentle if you go with a tapped threaded pipe plug as the taper can crack the casting if you screw it in too much. Be sure to use a good pipe dope rated for high temps since its near to the exhaust port and be careful about mixing incompatible metals especially in that high temperature location.

    Be sure to flush it completely with distilled water mixed with white vinegar followed by a thorough rinse with several gallons of distilled water. I use a metal wet vac to ensure the most complete evacuation of the old coolant and vinegar flush.

    Afterwards be sure to use a high grade coolant with distilled water or pre-mixed to ensure corrosion protection is good and consider doing annual coolant flushes instead of every two years.

    This should not be a death stroke unless the coolant has not been flushed for years or someone put in a coolant that was not rated for a mixed metal system. Could be due to the prior owner which is why I shy away from used bikes unless they are almost free.

    I feel your pain and hope there is only the obvious to deal with.

    managed to track down a plug, make a tool and get back on the road. ABSOLUTELY NO HELP FROM PIAGGIO. Will never buy another product of theirs..although the 350 is the best scooter I have owned....except for tech support. Talk about a cold shoulder.
    HORRIBLE!! If anyone finds this thread via google feel free to email me for details of this fix. jacksmetal@gmail.com. I think the plug was defective...read that some used in the 2013 were...not sure what the problem was...don't think it was the antifreeze age.
