MK3 Fiesta with 1.6 CHV engien swap. No heat/High Idle/broken rev counter.
I have just brought a MK3 fiesta with a 1.6 engine swap. It has a few issues i will list.
Heat does not work = suspected heater core as foot well is slightly damp. How do i connect a new heater core to the 1.6 engine?
High Idle - Seems to idle a bit high.
Bit smokey on startup
Fuel smell inside the car.
How would i go about troubleshooting?

Your asking a big ask there mate .
wot engine was in it before
Wot engine is in it nowDose it have the right ECU in it for the new engine
And so on . As much info as possible would be a great help to lads that have done this before

CVH 1.6 from a escort is in there now.
I'm not sure what ecu is in there now. How would i check? The rev counter is sporadic if that helps.

Oh dear. What engine code do you have?
It's probably the Escort MK4 2V engine with 90 hp. So there's no ECU.
It's obvious why your heater won't work. The hoses on the thermostate housing and the water pump have been blanked.
The high idle can have a lot of reasons. But there's so many looking so wrong on this engine I don't really want to think about which blanked hose, cable tie or loose connector might be the reason. Plus the carb probably needs a rebuild + a proper setup.
The rev counter probably doesn't work because the signal wire wasn't connected properly when the engine was thrown into the car.
Smoke on startup? White or blue? White is water, check for the head gasket first. Blue is oil, probably the valve stem seals.
Fuel smell? Probably not the right combination of fuel tank/fuel pump/carb/breather/whatever. Or just a major issue caused by the people who put the engine into this car.

Is there a way for me to fix the rev counter?
What would you suggest i do with this engine? Is it worth keeping or putting something new in?

The engine code is on the opposite side. The part numbers of the engine/gearbox casting won't tell you anything about the internals etc.
There was such an engine for the MK3 Fiesta (Fiesta S) that wasn't sold over here. But it has the wrong early type water pump. MK3 Fiestas had the later type with only one big outlet. But then you'll also need not just the hoses that are missing (heater matrix -> water pump and thermostate housing -> heater matrix) but also the right hose between water pump, rad and header tank.
It's nearly impossible to find the reason why the rev counter isn't working over the internet. Just check the wires between distributor and the rev counter. When there's something wrong with the wiring (usually the green one) put in a new one.

Hi from what i can read the top reads 81sm6090 1.6. Are these one of the early heads? Where did this engine come from?
Anything i need to know about this engine?

Wrong. Three letters. Something like LUD, LUH, LUJ etc.
Motorcode. On the RIGHT SIDE (gearbox side) of the manifold flange. Front of the engine.

That clears things up.
Block/head is a MK3 Escort unit, but it came with a Ford VV carb like the smaller 1.1 and 1.3 engines had. The engine had 58 kW/ 79 PS.
This one has been converted to a Weber 2V carb like it was used in the later MK2 XR2 with the lean burn head. It would be good to know what kind of carb was used.
There were a lot CVH engines out there with a 2V carb, (inlet manifold must be from a CVH) from 1.4 with ~70-75 hp to the XR2 MK2 with 97 hp. 1.6 CVHs with a 2V carb range from the mentioned 79 to 97 hp. The carb being too small (maybe a 1.4 unit?) might cause your problems.
The air filter box is a OHV one, that's the reason why it was cut.
Do you REALLY want to keep it???
1. take the head off, put in a new head gasket and new valve stem seals.
2. take the carb off, check if it's big enough, XR2 MK2 had a 28/32 TLDM, not sure about the MK3 Fiesta S with 90 hp. If it's big enough, give it a full service.
3. either go for a later water pump and get the MK3 Fiesta hoses you need OR keep the water pump and get the Escort MK3/Fiesta MK2 pre-86 hoses for the heater matrix (to/from water pump and thermostate housing)
4. I'm not sure about the compression ratio, but it SHOULD be the same as the XR engines had (9,5:1). 79 hp could be the result of the smaller VV carb or/and a different camshaft. Get a XR2 carb camshaft or an aftermarket part. I'd go for nothing too crazy, maybe a 285 or 290° one. People say Newman sell good camshafts for the CVH.

1) I will do this, is this the gasket set i need? It also looks like it has the valve stem seals. I've some that are top hat, is it worth going for these? https://www.ebay.co.uk/itm/HEAD-GASK...4AAOxyHQlSD3Dy
2) How would i check is the carb is big enough? I will probably check this before buying the gaskets. Do you need the model number of the carb? If i changed the carb is there one you would suggest? I will start looking on ebay.
3) Do i need to change the inlet manifold?
4) The hose going from the crankcase to the cam cover is ROCK hard, are these supposed to be like this? Where would i get a new hose? Can you just make one?
5) If the rings are worn can you just put some new rings in?
6) Do you know what gearbox is installed? 87TT-7F096-BB
"The air filter box is a OHV one, that's the reason why it was cut."? What does this mean?
Thanks for your help

Hi that is great thanks. Yes i will keep it, it is cheap car the wheels and shell are worth more than i paid for it. It is hard to get the type of driving experience this car offers for the price paid. I do not need a performance machine, just want something that does not smoke and is generally reliable. Parts are cheap enough, without a new carb could get this sorted for under 100Ł

2. I'm not a carb expert... it should have some part numbers cast somewhere?
3. Probably not. But I'd go for a whole XR2 (early square type DFT 32/34 carb/XR3 setup)
4. No matter when it's rock hard as long as it's got no holes!? You can replace it but you need oil resistant hoses.
5. Rings? Valve seats? Piston rings???
7. No. This is just the part number of the cast case.
Look at it... there's a part missing. On a CVH it goes across the rocker cover, on an OHV to the side, just as it was with your box.

1. 31 quid for a multi-purpose gasket set AND the head bolts??? Buy a quality gasket like Reinz or Goetze.

I am starting to put a part list together. I have come across two head gaskets the Payen and the Reinz.
1) Ive checked the number on the side of the carb it says 23-21. Is this carb suitable for a 1.6? (no cat)
2) I understand Payen make the ford ones, are they any good, better than Reinz?
3) Ive included a set of uprated valve stem seals, I understand these will work in my car?
4) Ive included a piston ring set, if 2 cylinders need new rings can I just put them on? Is there anything special I need to do?
5) What exhaust manifold gasket will I need? Part number 89SF9430EB.
6) While I am digging in the engine bay is there any preventative things I should do?
7) I do not need to worry about fuel injector deals with this engine?
8) Can this engine even run on unleaded? It is the 80-86 engine?
Please see parts list below. I will track my progress one work starts.

I really appreciate your help, hopefully I can keep this CVH on the road.

I'm not a carb expert. As mentioned before, the later XR2 had a 28/32 carb. If it's a 21/23 carb it's far too small.
I just use Reinz or Goetze head gaskets. Payen seems to be a bigger brand, for sure better than the first no-name one on ebay. Buying as a whole set with valve stem seals etc. is cheaper.
And yes, you should always use the later "hat type" valve stem seals.
I wouldn't mess around with changing rings on two pistons... either do all (and then check for ring clearance, piston clearance and use new bearings AND bolts) or none.
On such an engine you can usually use any exhaust manifold gasked you want to use. Thin sheet metal type, sandwich type, round exhaust ports, square ports... won't matter.
Preventive things? A full rebuild maybe? *lol*
No, it has a carb, therefore the are no fuel injectors.
Depends on the age of the head. When it's off, check for the cast markings on the back side. ALL CVH heads from January 1985 on can be used with unleaded fuel. Heads cast until December 84 will have "LPG" stamped near the exhaust port of the first cylinder IF they have hardened valve seats.

Block/head is a MK3 Escort unit, but it came with a Ford VV carb like the smaller 1.1 and 1.3 engines had. The engine had 58 kW/ 79 PS.
This one has been converted to a Weber 2V carb like it was used in the later MK2 XR2 with the lean burn head. It would be good to know what kind of carb was used.
There were a lot CVH engines out there with a 2V carb, (inlet manifold must be from a CVH) from 1.4 with ~70-75 hp to the XR2 MK2 with 97 hp. 1.6 CVHs with a 2V carb range from the mentioned 79 to 97 hp. The carb being too small (maybe a 1.4 unit?) might cause your problems.
The air filter box is a OHV one, that's the reason why it was cut.
Do you REALLY want to keep it???
1. take the head off, put in a new head gasket and new valve stem seals.
2. take the carb off, check if it's big enough, XR2 MK2 had a 28/32 TLDM, not sure about the MK3 Fiesta S with 90 hp. If it's big enough, give it a full service.
3. either go for a later water pump and get the MK3 Fiesta hoses you need OR keep the water pump and get the Escort MK3/Fiesta MK2 pre-86 hoses for the heater matrix (to/from water pump and thermostate housing)
4. I'm not sure about the compression ratio, but it SHOULD be the same as the XR engines had (9,5:1). 79 hp could be the result of the smaller VV carb or/and a different camshaft. Get a XR2 carb camshaft or an aftermarket part. I'd go for nothing too crazy, maybe a 285 or 290° one. People say Newman sell good camshafts for the CVH.

Would a engine with BRA code drop into this car?
Are heads/bottom ends interchangable?

I'm not a carb expert. As mentioned before, the later XR2 had a 28/32 carb. If it's a 21/23 carb it's far too small.
I just use Reinz or Goetze head gaskets. Payen seems to be a bigger brand, for sure better than the first no-name one on ebay. Buying as a whole set with valve stem seals etc. is cheaper.
And yes, you should always use the later "hat type" valve stem seals.
I wouldn't mess around with changing rings on two pistons... either do all (and then check for ring clearance, piston clearance and use new bearings AND bolts) or none.
On such an engine you can usually use any exhaust manifold gasked you want to use. Thin sheet metal type, sandwich type, round exhaust ports, square ports... won't matter.
Preventive things? A full rebuild maybe? *lol*
No, it has a carb, therefore the are no fuel injectors.
Depends on the age of the head. When it's off, check for the cast markings on the back side. ALL CVH heads from January 1985 on can be used with unleaded fuel. Heads cast until December 84 will have "LPG" stamped near the exhaust port of the first cylinder IF they have hardened valve seats.

averages dry
c1 - 123
c2 - 180
c3 - 160
c4 - 180
average wet
c1 - 140
c3 - 175
Though ti would this before tearing the engine down, it seems C1 and 3 have low compression. I do not mind if the car is not as powerful as factory, but just want it to stop smoking.
How would i address the piston issue? Is it worth getting a 1.8 zetec instead?
