MK1 BX16 TRS 'SE' - Make it or break it, a tale of neglect and fondling

Recommended Posts

Thanks folks, will ask around.

Regarding the TRS, tinkering has occurred. It is idling waaaaay better now, and starts alot easier although it still misfires under load. I haven;t checked the cambelt for a slipped belt, also the distributor isn't in the middle of it's adjustment so may tweak that - the distributor on my similarly XU engined GT also almost dead central in it's adjustment range. I also had a reccy at the lights, I swapped over the RHD headlights and put in some old headlamps I had lying around, all lights worked except for the front indicators! A clean of the contacts saw that right, so now all exterior lights work.

New bits!


I replaced the fuel filter, they are very cheap and i'd hope it at least would help it's running. The old one didn't look too bad, but it is at least 10 years old and soaked with old fuel. I put a new fuel pump to filter hose section in too, as it was splitting.



 I also replaced the thermostat as the radiator coolant wasn;'t getting hot after a reasonable amoun tof idling, I wasn't confident the stat was opening and was worried it was stuck closed. When I took it out, it could be pushed open, but that doesn;t necessarily mean it opened at temperature, new ones are cheap so replaced anyway. Coolant is a very satisfying bright green! Old stat is tarnished but both are stamped 82 degrees so I managed to find the right one after all, there was quite a lot of choice, my thoughts were an automatic would need the lowest opening temperature. The new stat was very very slightly too big and wouldn't sit recessed in the housing, so I used the chunkiest O-ring so a good seal could be made, no leaks so far! Quite a lot of coolant escaped during the replacement, so I ran the engine until the coolant level dropped (=stat opening) and topped it up and once the temperature rose, the low speed fan came on! So the fans do work, this is good news. On closer inspection, the radiator seems quite good too - which means I hopefully don't have to buy a new one when it gst swapped to the GT, they're fecking expensive, these twin-fan radiators as used in the 16v and TD BX's.


NExt I looked at fixing the LHM leak, it was a return line from the FDV to the LHM reservoir, a new pipe section is over £100! So as it was a low pressure return line, I made one up out of 8mm fuel hose, a couple of connectors and some pipe clips. The old pipe was broken at the T piece.


There aare three connections, the existing sound pipe to the reservoir, the FDV return line and possibly an accumulator or power steering return?


The home made Y piece, couldn't find a T piece locally. I hope the plastic inline and Y piece connectors stand upto the task, I would have gone with metal/brass etc if there was an option so these will hav e to do for now. I will keep an eye out for leaks, but there are none so far.



All done! So I now have confidence in the cooling system, there are no current LHM leaks (risky statement on an ancient BX!), the ignition system is mostly new (all except coil and ignition module) and the fuel system is liekwise sorted (not carb, this may yet be the running issue under load). So it is ready to be moved over to the barn where it's bigger sibling, the GT is, they can snuggle up together then until I finish my studying next June-ish. There should be room for the two of them in my end of the barn, the owner is my husbands Aunt and so far took no money from me for storage, but I have insisted now that I will have two in there, the other end is also used for car storage by someone else - but mine are way more interesting compared to a new Mini and smart fortwo!

      So a couple of weeks ago I was up at Mathewsons for the auction. I’d bid on a couple of things that didn’t meet reserve. Getting towards the end and this came through. Still didn’t meet reserve but got the call a couple of days later to say my bid had been accepted. 
      Anyway, we have a caravan at Primrose Valley so had arranged collection for today. First stint is just from Thornton-le-Dale to Filey which is about 18miles. Then tomorrow will be Filey to Leicester either via Humber bridge and Lincoln or Driffield then M18 and M1. Choice of route will depend on how it behaves today and how confident I am that it will be happy on the motorway. 
      Car collected now and refreshments of Tea and Scones consumed, we are off for petrol with Mrs Foxache following in the modern.

      Here’s how this thread is going to work. Attached pic is what I have sold. You don’t have to guess what the vehicle is, you have to guess which two well known Shiters are coming to pick it up, what pile of crap they’re coming in and where the mugs they are coming from. They’re arriving at 2pm on Saturday. Go!
      I have hints to drop including detailed personal descriptions and I’m funny so this thread will be funny.
