2005 Swirlplates.

Reading in the threads around here when I came upon this one posted by S2 (Thanks S2 good read).

What caught my eye was the parts that I bolded.
Quote:
2.0L Duratec 136hp (101kW) 136lb-ft (184N-m)
- Standard on the (non-ST) 2005+ Focus.

The Duratec 2.0 '993' is a 2.0 L (122 CID; 1998 cc) version built in Chihuahua, Chihuahua, Mexico. Bore is 87.5 mm (3.44 in) and stroke is 83.1 mm (3.27 in).

It is used in the US/Argentinian Focus and the Brazilian Ford EcoSport. (European Fiesta ST, Ford Focus and Focus C-Max, Mondeo, S-Max, Transit and Galaxy use Duratec HE engines). On the 2007 Focus, output is 136 hp (101 kW) at 6000 rpm with 136 ftlbf (184 Nm) of torque at 4250 rpm. The 2007 Focus sold in the US states of CA, NY, MA, VT and ME comes with the required PZEV emissions 20E version which produces 130 hp (97 kW) at 6000 rpm with 129 ftlbf (175 Nm) of torque at 4000 rpm. The PZEV is available as an option in border states. The compression ratio for both versions is 10:1. It has an aluminum engine block and aluminum DOHC cylinder heads. The cylinders are lined with cast iron. It uses SFI fuel injection, has 4 valves per cylinder and features fracture-split forged powder metal connecting rods, a one-piece cast crankshaft, and a cast aluminum or reinforced plastic intake manifold. It does not have variable valve timing. The power output is less than the Mazda version which does have VVT.

The plastic intake manifold on early versions has a major fault due to poor quality materials. The manifold has swirlplates mounted on a square shaft at the aperture where it mounts to the cylinder head. Early 4 cylinder Duratec engines can be ruined when the swirlplates break off and enter a cylinder. Most cases are of single swirlplates but also the shaft can wear and break. Early signs of this fault are evidenced by a ticking noise emanating from the front of the engine. This can occur as early as 25K miles, with failure typically occurring after about 90K miles.
I noticed that it states "early versions".

My question is does anybody know at what point they corrected this flaw and/or the safe cutoff date for the 2005?

The reason I ask is that I'm in the process of looking for a Focus and if I come across a 2005, buying it would be predicated on knowing that I'm NOT purchasing one with this design flaw.

Thanks again everyone.

I have never heard of them breaking and falling into the engine. At least no one on any board I read has experienced it.

Edit: I even just checked the TSB and Recall database, and there are zero references to this at all. Who wrote this?

yea, that is news to me...kinda scary if this is true because it pretty critical. Its also pretty amazing that i havent heard of this happening to anyone though, so i wouldnt worry about it.

Unless all that ticking we blame for the fuel injectors is actually this

Swirlplates.

I originally posted this in the general forum with only a couple of responses and it was suggested to me that I re-post it specifically here.

If you have read this already sorry for the re-post.

While reading up on the focus I came across this article written in this forum.

What caught my eye was the parts that I bolded.

This is the only article ever seen about it and absolutely no one has had a problem like this that I've ever heard of. it sounds like if there was a problem it was 03-04. But as I've said, I've never seen nor heard of it at all. Notice theres no references where the article came from? a search also turned up nothing. Oh, and if the plate did break off it would fall to the bottom of the manifold, there is no way it could enter the cylinder as large as it is.
In other words, get the car and don't worry about it.

x2 I've moderated this forum for years and was active in it for years before that and have never heard of this happening.

I own an early duratec and never had an issue.
