Ouch


Can't say I can ever remember this happening on an ST of any spec, I can vaguely remember something but maybe this was ST170 related and not on the ST.

Are we sure the part is identical to that used on the ST? i.e. part numbers identical which you can't always tell just from looking. I think some of Ford's blurb said the inlet manifold was different on the RS?

yes pretty sure that is the same as on out st,s when they say the indction side to the engine is diffrent on the rs i think its the air intake and filter which is refered to (i.e before the turbo) maby this is becuse the rs is running more boost? but still i wouldnt of thought wud have been enough for that to happen maby they were modded running even more boost
either way ouch

Have never seen this on an ST but have seen similar on a few cars, a back fire causes the manifold to split.

Have also seen a few modded motors running NOS blowing the manifolds apart.

Makes a funny mess.

We are obviously looking at this on the RS site. Seems strange that of the two? reported cars they are both in Germany and both on the same forum.

Leads me to believe that some common denominator will surface, and it's unlikely to effect the ST.

Very strange as the inlet is also found on the ST and I have never heard of this happening even with highly modded ones.

This seems to be a problem for Ford i think

I will check my inlet manifold tomorrow and see if it a 1 piece plastic injection moulded part

The manufacturer off the part my have used the wrong grade off plastic to make them

And find out who made and what it is made out off

I used to be a plastic mould injection setter/tech

Looking at the photos Clint it appears to be in 2 halves plastic welded together, the busted one seems to have split apart along it's joined seam, also broken open by the throttle body but this might have been a stronger join in that area so the plastic broke rather than the joint itself, after the rest of it had started to open up. I'd imagine it would happen pretty quick once the intiial failure happened due to the inlet pressures involved.

You might be able to see a supplier code and material info on the photos of the split open one?

Every part should be stamped for the automotive industry for traceability

The firm i used to work for made parts for GM/BMW/Ford etc mostly parts for the ecu and electronic/electrical connectors

and yes we did have the old recall on some and it costs millions to sort it

Well if Ford come up with a fix involving jubilee clips round the manifold to hold it together they owe me royalties!

Although the ST and RS parts are interchangeable they have a different part number and when you look at them side by side there are some very small differences.

Looks like a quality issue when the two halfs are bonded together
