Change the head gasket, easy job an then u can have a look at the head see if its ok ie stem seals, valves etc.
Doing the head is easy im asuming urs is cvh like mine, well id never looked in an engine untill a few months back when i decided to do mine, all i did was ask people on here how to do it an trust me its easy, no more than a 3hour job for a bigginer. the only thing u do need is acces to a tourque wrentch(cvh`s need to be right an there very tight).
im sure that would sort the running side out but as for electrics i dont have a scooby doo there
if ya need any help with head gasket info jus giz a shout fella

1297 HCS is a push rod engine, nothing in common with CVH.
The speedo will be either the dial face has bent and is pressing against the needle, or the cable is dry, and it sticks then when gets wound up enough inside outer cable jarrs free spins really fast as it has to unwind, does this over and over again, hence neddle going up down, often if you just grease the inner cable, then run it through a rag in your hand to get excess grease off it will be fine afterwards.
Rev counter could also be the needle is jammed against the dial face, these lift around the centre and jam the needles very common, they are just a voltmetre really with a different face, and feed from negative side of coil, if the engine is nice and smooth the coil is ok.
Don't go taking the head off, do the basics first good service, check co, your lambda could be up the swanny.
The valve clearances will need doing they are atrocious for this sounding like a bag of nails!!
Just be aware that you cannot use the rule of 9 on these engines as the firting order is 1243, and not the more normal 1342, but still easy to do.
The lack of speed is only going to be something basic so don't worry too much, could be something really silly like a really stretched accelerator cable!!

the speedo could also be the plastic drive in the box as these are prone to wear and quite an easy fix. also the cable is prone to wear into a round shape when it should be square shaped when it enters the back of the clock and also on the gearbox end.
there is a resistor near the coil which controls the rev clock and these are also prone to dying.
Tappets are prone to wear and should be checked.

well if i was to get say a bonus or l speedo unit would it be a straight fit as iam not botherd about the clock working just as long as the speedo and temp - fuel gauge work and think i will give it a service at work

I can't see the loom being any different, although if anything it might need a pin position or two moving.
Never done it on these mk escorts, have on 3 and 2.
Best way is to look at the pin/wire colours on the different ones in scrappies, that's what I do.

Probably adtrader would be best, I will have a look in my scrappies next time I go there see if they have any.
You could always graft one in off another car though.
There was a brand new one on ebay, at silly money for a xr3i but would work ok.
