It’s looking highly likely this will be the route I’m forced to take. The gauges are all original and matching, I was hopeful I may be able to keep them that way. N

Thanks for all of your help, I’ll continue my investigations and report back with my findings. Nick

The sender is bolted just behind the bell housing, pump is located under the alternator. Pics attached sender pic is upside down sorry

I do have voltage at the sender and at the tacho albeit very little 0.23v at tickover 0.65 at guessing 2500rpm actual engine speed. This displays 300rpm and 700rpm respectively on the tacho gauge. unfortunately I don’t have Hz on my multimeter, could borrow one to check the output tho. Nick

That’s the set I just picked up from machine mart 👍🏼

Thanks for this, I’ll source the crows foot and re-torque over the weekend. I already have the manual you linked, I knew it’d come in handy one day out of interest do any of you guys know where to source a replacement tacho sender (tin can) looking version for a yazaki tacho with two blue wires? Thanks again Nick

Hi Tony, thanks for taking the time to reply. No signs of concern in the year I’ve had it, it’s possible it could’ve lost around 1/2ltr of coolant from the exchanger but that’d be assuming it was full up when I last checked in the autumn. For which I can’t honestly remember. No oil in the coolant, no sign of water in the oil or oil loss. oil pressure and temperature have always been spot on, starts on the button even in the last couple of weeks at sub zero temps. 20 seconds of glow plug and will start in 2-3 seconds of cranking. This is the first year I’ve managed to start prepping for the season early to avoid missing the good bits of boating when the weather allows. Also hoping to cruise to the upper Thames in the summer hence the thorough going over and renewal of suspect Parts and hoses etc. I’ll try and get a good days cruising in the next couple of weeks and observe the fluid levels. Also De-grease the block to see if any and how much is leaking by. I’m sure I read somewhere about re torquing the Bmc heads but can’t for the life of me find it, did I imagine that? Nick Thanks Pete 👍🏼

Hi all, This is my first post, been a voyeur of the forum for a couple of years through Google searches sending me here, but now I’m in need of some of you guys knowledge directly. I have a 1978 Cambridge Carrington 27 with a 1.8 BMC which starts and runs great, was overhauling the whole cooling system yesterday (Raw and closed) when I ran up to temperature I noticed what looked to be combustion gases creeping from the head below the injector rail. One of the injector nuts had a little leak which I nipped up and all was well, thought that maybe it was just the diesel residue burning off as it hit the hot block. On close inspection it looks as tho the head gasket could be letting by (see video) any thoughts on this would be much appreciated. The video is really short but it shows what’s looks to be bubbling at the gasket, needs to be played at 720p to clearly see the detail. TIA Nick
