The last we saw our hero working on his Beetle, he had an intake manifold that didn't fit (from a company in Effingham, Illinois. Ahem).
So I bought another one from CB performance. The heat riser tubes are separate pieces that slot into the center section, so that it's adjustable. So I cut them down until the thing fit. So this afternoon, for the first time, the intake manifold is assembled, and the heat riser ends are fastened to the muffler on both sides.
Left side, manifold outlined in green, red indicates the heat riser flange that didn't fit with the first one but does with the new one:
Right side, same thing:
I called the vendor and asked how I was supposed to attach the side tubes. They said they don't need to be attached; they just seal up with soot. I prefer for them to be attached and sealed somewhat. I picked up some JB weld, a two-part metal bonding agent. We'll see how that goes:
So with the intake manifold all put together, I've put JB Weld on the joints.
I'll let this cure overnight. That will slightly fasten the ends into the center section. Then I'll take it all apart, seal it better again, and then I can (finally) continue the assembly.
