If the starter is clicking then I would suggest the car is trying to crank it but it will not as you have a flat battery or missed of a cable or two, earth strap etc.

Earth cables all day long. At that Age I would be changing them all.

CT1.

Same size tanks?

I would say it is pretty much impossible to physically check the clutch whilst still in the car, but as you have done a good few miles since then it should be no worries.

17mm spanner and crack any injector pipe union, then crank it over and let us know what you are getting

Normal ones have three point of contact, the one in your pic only has two, door one does not so much take any load but stops it shaking about to much, bit like your feet carry you up the stairs but every now and then being able to hold onto the handrail makes you feel secure. As for which is...

Do you mean EGR valve?

A thin smear of grewase on the pins to stop things sticking, then injecta. littel silicone selamt into the femal Bet it will catch as you refit the flaps, maybe try a thin smear of grease on the pins, then some silicone sealant in the female part, refit flap and leave silicone to set.

Steam cleaner to clean the tank out. You want nylon air brake pipe for the fuel hoses.

Is there any way it attaches/pivots to the rear door? if not that is going to give that tub some serious grief.

Iirc the series x member has some holes in the bottom face, this is for a piece of angle iron to attach to to allow the drop plate to fix to the angle iron to save twisting the rear x member.

Think only the other week someone on here was selling a freshly skimmed 200 flywheel. As it is an arse job to get box out once the car is together I would be inclined to sort it out while it is easy to get at.

Are you sure the crank did not move a back/forth a knatts cock as you rotated it? ie the amount of play in the crank thrust bearing.

I was always up the hospital having my eyes cleared /dug out when I was younger, still don't wear safety anything! but am much more aware.

Gaiter has grease in it, there is a seal in the diff that the drive shaft fits in.

So long as it sits sort of level the actual numbers mean diddly squat. Any codes?

Looks pretty ugly, but I see plenty of people driving them small jeeps, and they are far uglier!

The plastic rads are okay, the metal ones are better.
