Hot running V8

Greetings One and All

It's been a while - hope all is well in afl land.

The Land Rover (V8) has taken to running hot lately.

Symptoms ...
Temp Guage just below 'red'.
Pre-ignition.
Header tank empties but I can't see where to.

Vehicle runs fine but I don't like to stress it.

Any clues to trouble-shooting appreciated.

Which brings me on to .... can anyone recommend a Land Rover mechanic in
the Twickenham/Heathrow area - there's a couple of other minor niggles I'd
like to sort before Christmas and time is running short.

Thanks for reading.

Sounds a bit like a leaking head gasket to me. I'd start with a
pressure test of the cooling system, and see if it's losing pressure,
then if there's no signs of any external leaks it might be head off time.

Ugh - could be I guess. Oil and exhaust appear to be satisfactory to my
untrained eye.

how?

Which brings us nicely back to the search for a reliable mech.

Re: Hot running V8

it could be the ignition timing has changed , get timing checked .

the pre igniting sounds like timing is out .


see below in case you have this problem occurred .

is the locking bolt for the distributor ok, check around the bolt hole
boss to see if engine block casting is cracked at all , if it is get
it cleaned up and ali mig welded, mine cracked here and i couldnt hold
the distributor in place , you might think the bolt is holding it
because it will tighten , but the only way to check is to actually look
an see .
i mig welded mine ok without removing anything, just put damp rags all
around area and plenty water on them before welding .

A simple check to see if a head gasket has gone, is to top up the
radiator, leave the cap off, and start the engine. If the water in the
radiator starts blowing bubbles, it's a bad thing.......

Unfortunately not all head gasket leaks actually blow out through the
cooling system. But it's a good start.
