Cortina MK1 steering box oil seal.

I’m leaking oil out of my steering box , running down the drop arm, I see there is an oil seal just above where the drop arm bolts on. Does anyone know if this seal can be changed without removing the steering box? Looks like a pretty big job if it needs to come out. Thanks.

2019 events.

Is there an events calendar for touring car racing for 2019 covering Canada and the US? Been watching Goodwood revival clips on YouTube and would love to see something similar but this side of the pond. Might even be able to persuade the ‘trouble and strife’ to make a holiday of it......Thanks.

I’ve put it all back together again, I still try and use it as a daily driver. I’m sure everyone is tired of my issue anyway. I’ll look again during the winter when it’s off the road, I’ll check your suggestion then Pete. Thanks all.

Tried reversing polarity, checked all the grounds, still no change. One thing you mentioned stirred my curiosity Pete, ‘ staying too long on 0 volts and too short on 5 volts ‘ . The instruction leaflet that I got with the v/s mentions that it gives a constant 5 volts? When I check with a meter I...

Yes I made sure it’s grounded, in fact I added an extra ground to the whole speedo as the ground from the bulb connection didn’t seem too great. I don’t have a spare voltage stabilizer but surely the other gauges would be inacurate if it was faulty. I think I’ll try and run a wire straight f...

Yes I ran a separate ground from the tank to the battery to be certain. The sender seems to read accurately, the gauge seems to work correctly, the voltage stabilizer seems to work correctly . There really isn’t much else to it but it still isn’t giving an accurate reading . I have the sender ou...

Hi Pete, I’m using a MK1 fuel gauge, a new MK1 voltage stabilizer and a new MK1 20 ohm full, 200 ohm empty fuel sender. I get a reading on the gauge of half tank when it’s actually full, despite a reading of 20 ohms. I get the same, half tank reading when it’s actually full when I try hooking ...

So I get 12 volts to the voltage stabilizer. I get 5 volts out of the voltage stabilizer. I have the sender out and it reads 20 full and 200 empty when I move it manually. I have hooked up my MK2 fuel gauge using the MK1 wiring harness and that reads half full when I manually move the sender arm to ...

Ok I’ll check when I’m back home on the weekend, voltage stabilizer is new so I’ll check my connections. Thanks Pete I’ll let you know what I find.

Hi Pete, so I have 3 volts at the sender, 1.8 volts at the gauge. My son is currently at school and has done a chart, you probably understand it better than me but I’m not sure from the figures what the issue is. Thanks for looking at it. http://www.enfostuff.com/forum/userpix/485_217007E7DEEC4609...

Any tips here will be welcomed. So I have installed a new sender unit and with a full tank I get 20 ohms but still get a reading on the gauge as half a tank? A little confusing, I tried a gauge out of a MK 2 and get the same reading so I’m pretty sure the gauge is ok. I thought it might be a probl...

Just an update to anyone that is interested. I removed the section between the carbs and the head and the difference is black and white. The increase in power is quite something. I have adjusted the timing and now I have it running at about 14 BTDC. The idle is not as smooth but I can probably get s...

So it looks like the sprockets and cams are correctly aligned, markers line up and I can just about make out an EX on the exhaust cam sprocket. Number 1 and 4 are slightly open so I think I’m good here, thankfully. I guess I’ll look up the correct valve clearances whilst they are accessible. htt...

So if I remove the rocker cover I should be able to check the alignment marks on the cam sprockets when at tdc , from what I read they should be horizontal and pointing at each other if correct. I see what you mean by ‘ ballpark’ accuracy on the screwdriver test, room for error there. I’ll set...
