Difference in Zetec valve covers

[das76]

Hi folks with Zetecs, I'm curious as to the differences in the Zetecs and or valve covers I've seen on a few Caterhams.

 

My car looks like this (Zetec from a 2003 Focus) and has a sensor of some kind in front of the forward spark plug/cylinder

 

 

But some others look like this. The valve cover is simpler - cleaner  - Ford Zetec marked on it - but no sensor in front of the forward cylinder.

There are about 3 different Zetecs in US (2.0)

 

Regular Zetec with no timing

 

VCT (Variable Cam Timing) Zetec with cam timing adjuster (the sensor you see) on Exhaust cam (for emissions now HP, typically gets disabled, mine is)

 

SVT (Special Vehicle Team) Zetec that you have is quite different in almost every single way (tell tale is the hills and valleys/chocolate bars style valve cover) and you having variable timing on the Intake cam. Not sure if its for HP or emissions as well. Likely HP

awesome, thanks @Vovchandr

 

I'd love to tidy up the engine bay - it seems quite busy, but I'm not sure how much can be done with the SVT in there, as I'm sure it's more complicated for a reason (likely more HP). It's definitely low priority - basically a make work project - haha.

 

But I'm open to ideas if you've seen any!

ITB's will likely be your best bet to clean up and simplify the engine bay and get more HP.

 

However you'll need standalone ECU and a tune afterwards.

 

You can also do Raceline water rail to clean up cooling

 

Wrap your headers.

 

That's about it.

 

Ironically it would look very similar to the second picture you posted.

Thanks. I posted here last year about ITBs and that sounded like a bigger project than i'm willing to take on.

 

I'll look into the Raceline water rail - thanks for the tip. Do you run this on yours?

I do not. I was planning to use this as a solution for my cooling issues so I contacted them. 

 

After them being helpful and putting an order together they just kind of stopped replying. After 3 follow up emails from me to them and my cooling issues so far sorting themselves out I didn't feel that my wallet was too heavy and needed any lightness added to it. 

 

ITBs are a huge commitment with a pretty big payoff. That's why many people bear the pain.
