rog1300 Posted June 1, 2023 Share Posted June 1, 2023 Well finally got round to sorting my Mk4 1300 rear end whine. Hadn't done a U/J in over 25 years but did both drive shafts. As expected, no change, but it's a tick in the box of jobs to do. Took a punt on an ebay "gold" (hmm) differential. Asked questions etc and seemed a better bet to spend £250 rather than the initial £1k outlay for a fully recon one. Having removed the rear leaf spring I ended up ordering a new one of those too! So all installed now with loads of new bolts and exhaust downpipe to manifold gasket. (hadn't expected that one on the list to begin with). Fun job on your own! Have also installed dashboard ignition switch with push start and moved lights and fuel pump to switched control in Dash with relays. All looking and working great. First trip out last night proved there is a coil voltage solution to be found now as she starts on the button but conks out after a few yards - no power at all. Ho Hum... more thinking to be done. Hope everyone is good and getting their pride and joys out in the sunshine. I'll be there too again soon I hope. 4 Quote Link to comment Share on other sites More sharing options...
rog1300 Posted June 2, 2023 Author Share Posted June 2, 2023 Coil tested good! 3ohm gold Lucas unit. 2.9ohms on volt meter - minus the 0.2ohm on meter with contacts closed. Ign on and batt V at 12.7 at +ve coil terminal/ 11.6V with -ve term earthed temporarily. Started chekcing the sparky parts as I'd just done the dash/ignition re-wiring so obvs thought that's where the prob is. However, next obvs thought was it sounds like a fuel problem. Opened float chamber - eugh - full of muck at bottom: crystalline crud - is this ethanol/water related corrosion? Car has been sitting for a few months to be fair! Still, one float chamber removed and cleaned up. 2nd to do, then I can test this part out...! 1 Quote Link to comment Share on other sites More sharing options...
John Bell1 Posted June 2, 2023 Share Posted June 2, 2023 Amazing what some gold paint can do! What does the diff sound like? Good luck! Quote Link to comment Share on other sites More sharing options...

I'll let you know once I get the carbs cleaned!! Just hope my fuel tank isn't full of the same rubbish now! Hoping the E5 fuel isn't too hydrophilic! 1 Quote Link to comment Share on other sites More sharing options...
rog1300 Posted August 2, 2023 Author Share Posted August 2, 2023 Rear end is sorted but seems the back of the engine was letting out oil at an ever increasing rate, along with sump gasket pretty wet, thought I would check the rear crank seal and sump seal. So with gearbox out and sump off I find the compression spring for the crank seal sitting in the bottom of the sump!! Oil pick up filter gunged up too. All cleaned up now. New gaskets fitted and back on car. New clutch ordered and release bearing arm parts just arrived for replacement: slave cyl push rod and lever pin and pivot pin etc as all badly worn and causing slop. and it's raining again. Smile and wave boys, smile and wave. 2 Quote Link to comment Share on other sites More sharing options...
