hi everyone, long story short, ive suffered tensioner failure on my focus zetec s 1.6 2000. ive replaced the bent valves and reassembled to find that i now have great loss of power ( struggling up hills and with load) it may be clearances or valve seating causing the low compression on three cylinders(150 compared with 250lbs!) .. fed up now im asking for help from the experts and looking for a second hand head to slap on at low cost.

my question is this. i currently have this engine, with 4 bolts holding the rocker cover

anyone know if i can use the cylinder head from this engine ( from mk2 focus i believe) http://cgi.ebay.co.uk/FORD-1-6-ZETEC-SE-ENGINE-/250640024625?cmd=ViewItem&pt=UK_CarsParts_Vehicles _CarParts_SM&hash=item3a5b4f4431

im just using ebay as pictures as im confused as to identifying what these engines are referred to. zetec s/se/phase1/phase 2/silvertop/blacktop.. to me the heads do look the same with the exception of the rocker cover and how it is mounted (but i can get one with a rocker cover). any help/input regarding any of these issues would be greatly appreciated.

 

The engine in MK1/Facelift is defo the same engine the cam cover is different as it has Zetec S written on in your first link the same engine later featured a diffrent cam cover in your 2nd link with "Zetec SE" printed on it.

The same engine is also in the MK2 Focus but now comes under the Duratec name. This head maybe different as the model is avaliable in two power guises 100HP which the MK1 had and 115BHP (TI-VCT) the extra power is in the VVT.

TI-VCT - Twin Independant Variable Cam Timing

On the "Zetec S" cam cover the plugs are covered in and you need to remove the cover first, the cam covers may be interchangable but don't quote me on that.

The Blacktop/Silvertop are the two litre Zetec's which are totally unrelated to the Sigma family.

Edit: To add both of the links you mention are from Focus Mk1's

No they are not interchangeable unfortunately, the metal camcover engine you have is quite different to the plastic camcover version.

Your best bet is to keep an eye out on ebay/forums (you will most likely find your engine refered to as a 'phase one', and the same engine was fitted in focus/fiesta/puma of the same era)

 

thanks for that info!

ive seen from pics that the rockers are different and with more screws. but this shouldnt be a problem as i can fit one with the new cover Aside from this it should fit in my focus should it not? do you know if the cams and other stuff the same?

 

damn. james are you sure? the two engines in the pics have different cylinder heads? do you know in what way?

 

What his saying is you can not interchange cam covers between the two engines, however you could swap the complete cylinder head over from one another as almost certain the heads are the same baring the cam cover, certainly the rest of the engine is.

Thanks for that martin. the only thing im now concerned about is that my head has a hole for the idle pulley for the fan belt to go and im not sure if this is the same on the phase 2. is the auxillery belt arrangement the same in the two cars do you know martin??

 

99.9% sure they are the same the only difference I know of is the different cam cover and from what has now been said about the different bolt pattern.

The bottom ends (Crank bearings if i remember correctly) are different between the two engines, there are many small changes in them but from what i've read the head will fit straight on and all will be ok.

Although by the time you've put a new cambelt and headgasket on it etc (Recommened if you're having the head off really) I'd sooner put a whole engine in just to be on the safe side.

But if money doesnt permit it then just the head would do.

 

Black top has a different shim set up and shorter valve stems

 

Oh rite, was there any improvements to bottom end as there was a myth of phase 1's blowing up?
