I get lots of help from you guys, it's time to give a bit back- especially to people who are a long way from home...

Hope you enjoyed the fun. We were there yesterday and learned a great deal about what we could do in our Landy in sand.
We also upheld the honour of the Series III after being sent out the front on the convoy because we were the slowest, and running away from them such that they had to tell us to "Back off a bit..." <chortle>:p

Seems like the gasket hasn't blown into the oil galleries, just into the coolant, as they don't have any of the usual off-white frothy deposits you get with water in the oil. They have noticed a soft compression when turning it over with the crank handle, so seems like their diagnosis is probably correct.
They have been getting about 24 litres/100km which is way excessive. If the head gasket has been on the way out for some time, that might explain it, but with the same engine the worst we have had is 18 litres/100km and that was pushing into a strong headwind (like about 25-30 knots). They have the same carby as me (Zenith) but with some of the anti-pollution removed. They have done all the obvious things like tyre pressures, handbrake dragging, etc. Any suggestions as to adjustments they could make that might assist to reduce their fuel consumption a bit?
Cheers,

Coop
(Carbies are black magic to me...)

if its been retuned to compensate for the going headgasket and the loss of compression then they will be running rich and the carby will need a back to basics.

Tightening up the lash on the exhaust a touch and doing the tune up with the engine hot will be about the best you can do... IF alternatively they've had the carby running lean it might just be that thats whats taken the head gasket out.

May also have burnt out an exhaust valve if running too lean ................ I guess all will be revealed when head is removed but I'd suggest closely examining the valves/valve seats and rectifying any problems there before refitting head. Not forgetting the valve stem seals either.

So TC how things going?

Diagnosis yet?

(On TC's behalf)Just left them at the shed they got back with the spares this evening- they are up to their elbows in greasy stuff, the manifolds and sundry bits are off and I have the starter which also needs attention. Should have a diagnosis tomorrow after they remove the head...

good stuff mate

COOP, your a star, good on ya

go any pics of the ordeal

Head back on today- the head gasket was really blown- in fact the entire section between two adjacent cylinders had gone!! (No wonder their fuel consumption was a bit on the high side!) Awaiting parts for the starter- should be ready tomorrow morning, they'll install that before replacing the manifolds, carby and other sundry bits. With a little luck they'll be back on the road again tomorrow, ready to head North.
Will see if I can get a picture of the remains of the old gasket for you.... it's not a pretty sight!
