Well hose and exhaust were delivered a few days ago. Got the old exhaust off and new one on in about an hour. Started it up and it was very quiet. Then gave it a wee rev and the banging came back.
Turns out I have just replaced a perfectly fine exhaust. there is a plate that the exhaust connects to which then connects to the car. I think this is rattling of the exhaust and causing the noise, It only better because I tightened it up a bit when fitting the new exhaust. Still it should only be a 10 minute job when I have the time weather and inclination to sort it.
The water pipe though what a nightmare.
disconnected it from the radiator and the engine fine. But the connection to the water bottle which is tucked away inside the rear quater panel was a night mare. There is a small access panel in the form of a vent. So I undid all the faseners for the bottle including the pipe to the cap which goes through the frame. Only to find even after all this I cannot manouvere the bottle into a position where I can undo the jubilee clamp on the hose.
Lots of headscratching and I realised if the radiator and it's frame came out I could maybe access the water bottle from underneath reaching in from the bottom of the engine bay. This worked but took ages.
Once all done I took it for a run to build up some temperature to bleed the coolant system. Whilst on the run the car would suddenly die for a second before coming back alive. Kangaroo petrol type symtoms and when coasting the engine would cut out altogether.
Nicely though the car seems to have fixed this issue itself without me having to get dirty again. Although slightly noisey at certain revs thanks to the exhaust plate, it is running extremely well now and done over 100 miles in 2 days.
If this keeps up I may be loooking at mods sooner than expected.
