so I've got a nice rebuild long block, all the new parts you can think of and can't seem to figure out the o-ring/gasket that sits on the heater tube where it bolts to the under side of the intake manifold, this is the tube that runs around the back of the block. what came off looked like a ridged o-ring, but was not in the master rebuild kit, and the auto parts shops have no listing, of course it's a long weekend and the toyota dealership is closed.....help please. matt <img src="/forums/images/graemlins/confused.gif" alt="" /> <img src="/forums/images/graemlins/scared.gif" alt="" />
