Build your own 3.4 crossover pipe
#81
Although not exactly the same design, that looks functionally too similar to the 3VZ crossover to me. Read that as a hot cylinder 6. In reality, I wouldn't know how well it would function, but I would prefer a Y-pipe joining the left and right cylinder banks at a lower location. Or at least angle the pipe coming from the passenger's side back more. That is, the joint shouldn't be at a 90 degree angle, but more of a 45 degrees downwards, so the exhaust is less likely to back up into cylinder 6.

I know the angle is a little pitched in but I used extremely large exhaust tubing and restricted the hole a bit where it dumps in by using a hole saw that was only as large as the diameter where it exits the exhaust manifold flange. Will that make te hot cylinder situation any better or should I start from scratch?

Thanks for the heads up on that hot cylinder situation though!
Hopefully diverting the flow a bit will help

And I can't deny it,

Ok I finished up my wiring harness now it's back to fixing this damn crossover pipe so I can drop the engine in here is a side by side comparison of the first one I attempted and my new one I'm building

Rayl82 called me up and told me the pipe or weld broke on the crossover pipe, decided easiest route was pull trans, do a clutch while it is out, and pull pipe from bottom.
drivers head, pipe just off manifold broke just past the weld.
welded it back together, you can see the new weld just above the old weld
added some support so it can't happen again
got to thinking that he put a doubler in awhile back, and I think the mount has too much flex, and it was flexing the exhaust too much, so I told him to chain the mount, and ad more hangers, just in case.
and a current shot of the truck
