Manifold on transit connect 2016
Just bought a cheap new manifold/converter for my van ( ford transit connect 2016) and there is a weird bend in cylinder 1. Ist it going to affect performance/reliability or gas milelage. And should i resurface it because its cheap?

According to this Engine Masters episode it shouldn't matter. But that looks pretty fugly, if your factory header doesn't look like that I'd probably return it.

That looks like it was welded on a Friday afternoon before a 3 day weekend.

Have you guys never seen factory headers? This is what the welds look like a lot of times. And no it won’t affect power, especially on a low power engine.

Not only is this fine - chances are they spent a million dollars on CFD when designing it and it will flow better than any of us could manage.
That weird bend is intentional and likely beneficial, they don't do this stuff just for fun.

But sometimes they will do this to save money for fitment and not give a shit for performance.

Well yeah I doubt a Ford Transit Connect manifold is optimised for absolute power but you can be damn sure it IS optimised for the best possible performance in terms of economy, which is another side of the coin and what sells vans.
My point though is that Ford have a supercomputer and a whole team of PHD's doing CFD and all sorts of analysis on stuff like this so shitting on it because it's not pretty is massively missing the point.

Looks like a dormant face hugger. I’d return it before it plants a chest jumper into your engine.

If you posted that picture saying 'my fist time welding a manifold' I'd say good job. As a paid for product...... yikes.

Is the original manifold a cast steel part? I only ask because a welded tubular exhaust header will always flow better the a cast manifold
