XJ8, flooded
Been offered a cheap 1998 Jag V8 4 litre which has a flooded engine, apparently flooring it when trying to start is not a good idea on the V8. The
question is, is it a case of taking the plugs out and letting it dry out or is there another problem I should be aware of. All useful answers
welcomed.

Flooded with water (in a flood?) or flooded with petrol (so it won't start!)??

flooded with what? if petrol, i wouldn't have thought it should be a problem (in a sense of flooding and engine when you try starting it and
there's not enough air to fire etc)
or water, in which case i guess there could be bent valves and things?

if its flooded with petrol,remove plugs and fuel pimp relay/fuse,let it dry out a bit and heat the plugs with a blowtorch.
try to restart with easystart and pimp still inop.
if its water....walk away

Presuming there wasn't enough fuel in the pots to cause a hydrolock, I would take the plugs out and spin the engine over a few times and then
leave it overnight. Change the oil as it could be full of fuel, and then use a squirt of Easy Start to run the engine.

if its flooded with petrol i'll let it dry out, then squirt oil down the bores before spinning it up.
Great way to make a car impossible to start is to flood the engine and leave it, washes all the oil off the bores and the engine just spins but has no
compression. (guess how i know, i did it). Called the AA man out, he laughed and we spent 5 mins spinning the engine on the starter in 30 second
bursts, eventually it started to missfire, then 10 seconds later it fired.
Never started the engine cold driven 10m and parked it 24 hours since.

marcjagman - do a search on jaglovers. The guys on there are always doing the same thing. The procedure has been posted on there loads of times. Its a
common problem on the v8's and also apparently on the six's but iv never flooded mine. 
How long can i resist the temptation to drop a V8 in?

MikeR, surely, as soon as the oil pressure in the engine builds up, oil gets squirted up to the piston and through the oil holes? It should have oil
up there within a few seconds.

Owelly - i'd agree if i hadn't seen it in practice, the only thing i can think of is you need to 'wash' the petrol off the
bores.
Oh, the other part of this was keep your foot on the accelerator and clutch while cranking to make it as easy to crank the engine as possible and get
as much air through the engine. Just checked my new focus manual and it suggests the same for the petrols.
