Q1. I suspect you may have a bit of a mixture. The 1.6CVH wasn’t used in the Mk3 Fiesta as late as a L reg, it had been replaced by the Zetec by then and only in the XR2I and RS1800I, both 1.8’ The was a 1.6 CVH injection engine in the XR2i Mk3 Fiesta but it was earlier than an L reg Was the old engine fuel injected ?
The earlier H4’s didn’t have the holes for the Zetec engine mountings the later ones did, the easier way to tell is to look for the front mounting holes on the chassis rail. If you don’t have the holes they can be drilled but you also need an angled steel plate welded to the chassis rail (from memory). Apart from that a Zetec from a Mk3 Fiesta should have been a straight swap for a CVH from a Mk3 Fiesta, use the Zetec engine mountings. The lower engine mountings (on the cradle) are the same on both engines, as is the gearbox. I wonder one or the other of the engines was from an Escort and they have used the escort top mountings. Or, modified the CVH top engine mount to use on the Zetec, no real issues doing this if it is done correctly, it takes 260bhp in my 2+2, and Matthews Zetec turbo in his 2+2 But, using only the rear top Zetec mount won’t work as it’s not designed to handle forces in all directions, it has to have the front mount as well. If you can take some pictures we should be able to work out what is what. The engine should be straight and there should be no issues with belt, cover or radiator clearances. A thought, it’s not got a black plastic inlet manifold has it ? Q2. Escort mounts are different, the basic engine block is the same but the brackets and mountings are different. If you engine is from an Escort you will need some of the other castings as well to fit Fiesta mounts. Q3. Sounds normal, as long as the vent pipe is clear it should be ok. The vent pipe should be running up to a solenoid valve on the engine on the Zetec so the fumes can be sucked into the engine. I think the CVH just had the vent valve but otherwise no differences. Q4. Most people are fitting the power steering, if you’ve not driven a similar car without it you may change your mind. My 2+2 is quite a shock nowadays after driving cars with power steering. I don’t think the non power steering engines had the automatic tensioner, they were all manual adjustment on the alternator tension.

It may be New, but I'm keeping the receipt just in case. Secondly, I've a few queries which I've been meaning to raise for a long while and just never got around to, in spite of them being pretty fundamental to driving pleasure. I'm hoping one of the H4 gurus may be able to shed light or offer divine guidance. My H4 was built with a "regular" 1.6CVH engine from, I believe, and "L"-reg Fiesta. It was then re-engined with a 1.6 Zetec in order to provide the owner with power steering. However, there was evidently some difficulty in siting the engine as I realise it's been fitted slightly at an angle, so close to the off-side chassis member that the belt cover has had to be left off. In addition, the off-side front mounting which is present in the donor is absent in mine, and this permits excessive slewing of the engine on sharp left-hand turns and a truly unpleasant noise as one or other pulley attempts to chew its way to freedom through the chassis. (This led to a misalignment of the auxilliary drive belt, corrected at some cost.) It can't be any good for the drive shafts, either and may explain why the gear lever feels so damned far away (and I have long arms). On the positive side, it has made me a very considerate driver on left-hand bends. I've also noticed that the off-side rear mounting, near the suspension location, has two holes drilled in it, and I recall noticing the same thing in photographs posted here of rust on a Quantum H4 chassis: is this a standard arrangement? My engine uses the hole further back and towards the edge of the vehicle. Looking at it all, it seems that the radiator fan (from the original engine) would obstruct the engine were it fitted "straight", so Q1 is: does the Zetec have a slimmer radiator? I've seen after-market electrical fans with depths of under 3", so is one of these usually required? Q2. relates to the missing front engine mounting. A scrapyard search turned up no 1.6 Zetec Fiestas but one or two Escorts. However, they seem to have a different mounting system. Are the two interchangeable or were there specific Fiesta and Escort variants of the 1.6 Zetec? Is there any reliable after-market substitute for this mounting, as the Ford original is silly money! Q3. relates to fuel tank pressurisation. I've noticed an occasional hissing from the fuel filler cap, usually when the tank is less than half full. Is this likely simply to be worn seals on the filler cap or the neck on which it bears? The pipe from the top of the tank to the valve strapped to the filler neck seems to be open as blowing down it leads to pressure in the tank (cap hisses). Or is it that the Zetec fuel pressures are different to those of the 1.6CVH and some modification should have been made? Q4. relates to getting rid of the power steering, which just seems like a waste of horsepower to me. Is there a "standard" fix to replace the power steering pulley with a guide pulley to maintain auxilliary drive belt geometry and allow correct functioning of the automatic belt tensioner (what a great idea! So much easier then the system on a previous Fiesta I had which required torque wrenches, crow's foot adaptors and three hands to get the tension correct) ? I really should have trickle-fed all of these in over the course of the year but, there you go! Maybe I should book myself in for a Quantum H4 Masterclass - will provide assistance in return for enlightenment !
