wiffy, fumey landy

Stacked it · Apr 26, 2011

high all

My landy stinks! I nearly pass out if I am driving with the tilt on and the back open. I am thinking its just bad carb settings but I have set the mixture and it still well fumey. Could it be more sinister?
I have been running the engine - a 1958 early II petrol- for about 12 years with a weber carb and on unleaded. I have never had hardened valve seats put in and don't use an additive. The reason for this carelessness is that a) I have been planning to rebuild the original engine for 10 years and b) don't trust the additives.
Whats your thoughts, could it be carb or a knackered top end?

Time for that rebuild.

I thought someone would say that. Looks like its on then. Better dig out the old lump and see why it threw the oil all over the cab all those years ago then. Sad really as the current lump still pulls like a train.

Take the head off and see,most likely valves kaput bottom end may be ok if it still goes allright cant be all that bad.

I think I will just rebuild the origional engine and keep the one thats in there as a spare. Its been rebuilt once in the 60s so is probably only the top end. But I never intended it to last this long- 13 years, with two trips to Munich and back and one over the alps. Its breathing pretty heavily too.
With the full rebuild of the origional engine I can go the whole way. Re-bore, new rings, new cam etc... and unlead the head.

Sounds like it's drawing the exhaust fumes in through the back,I had a petrol boat that did that.

ah ha.
simple.
I remember the lovely smell of land rover engines in Germany, i think it is the low air pressure inside the tilt that draws in the exhaust fumes with a fair amount of nitrous oxide in the mix. Sort of minty heady niff....
seriously, is the engine ominously quiet? valve seat recession makes the top end clearances tighten up and the top end rattle goes altogether, just before it starts miss firing.
