SanDiegoPaul Posted November 6, 2007 Share Posted November 6, 2007 My old '79 pickup had the same type things on the 20R engine. It's like a motor mount; metal & rubber fused together. You've got the 10mm nut on top of the carb stud, and there are two other nuts that fasten the air cleaner housing on to the top of the valve cover. These nuts are on studs sticking out of these rubber thingamabobs. Where can you get the thingamabobs? I have one that broke & I tossed it last time I removed the air cleaner to replace vacuum hoses and the filter. Now the nut on the carb loosens up and the filter housing vibrates against the valve cover making a hideous noise on acceleration. I can of course tighten up that little 10mm nut on the carb, but a week later it's vibrating again. So I would love to buy a couple of those metal & rubber thingamabobs to fasten that housing down to the 22R valve cover like it's supposed to be. Suggestions?
