series 3 major problems after engine oil top up.

Mechanics looking at in now , he thinks it head gasket , would that explain banging/shudder? , mot is next week I can't even afford that without anything else !!! Love affair with Land Rover nearly over !

Possibly, blown head gasket can make it run rough.
HG isnt a massive issue if all else is good, though.

Letting the Engine OVERHEAT can cause a blown head gasket I refer to your first post that stated your Engine was overheating! Don't blame the series 3 just yet!

Due to the sump design on yhe 2.25 engines down steep slopes or heavy brake causes the oil to slosh forwards and up starving the oil pump.

A good thing to get for any old car is an oil pressure gauge. The oil pressure light only comes on when there is no oil pressure and by then the damage would have been done.

I've heard that the series 3 heater matrix can trap air if the heater tap wasn't open when you flushed it.
You could try starting it from cold with the rad cap off and seeing if it allows air to escape. You'll also be able to check the thermostat is working.

One thing is to trace all your steps and procedures when the oil and coolant was changed. Check that nothing was left loose or knocked off which could now be vibrating.

I know a lot of people give land rovers to garages when they are having problems but I never have and never will. You just can't guarantee if somethings been done right. Plus their heart won't be in it like it is for us. But that's a seperately topic

I had similar shuddering and banging when I'd over adjusted the hand brake. Maybe an outside chance. This may cause the engine to labour and get hotter. At the time I thought I had a serious engine / box issue. This would of course potentially be coincidence and unrelated to oil top up.

Oh dear. The symptoms are when it's driving. Your comment on the gears is key. The description sounds like something bad deep in the engine. Crankshaft. Red lights are to warn. Oil is going somewhere . Big end oil seal? I'd stop driving the vehicle and do a deep investigation. Have you had any other odd indications before this? What about the gear box seal. Have a look at what's underneath.

The oil light should be green shouldn't it? Are you sure you've not just overfilled it with oil - that can be nearly as bad as underfilling it

Won't start at all now , sounds similar to flat battery , mechanic thinks noise might be a coincidence and might be related to driveshaft and bad running starting may be due to ignition system which is always possible , I'll replace the whole front driveshaft to save messing about , have also discovered accelerator pedal feels a bit loose , could this be a simple thing that will solve all my problems ?

then why has it got 2 cylinders that are blacking plugs...

as an ex mechanic i can not in a million years from the symptoms you originally stated now get to it being ..drive shafts..maybe ..then ..ignition..maybe..flat battery not turning..it may be siezed in that now its cooled down its locked up in that when hot it would have been in expanded state...before you spend a penny please get a second opinion...of course im not there and so i can only go on the scenario on your facts as stated
do a compression test on 2 black plugs...jump it to see if it turns over freely

If it's possible you've overfilled the sump, is it possible the engine is dieseling?

Whereabouts are you Neil? A number of us are watching this and thinking that your mechanic may not have much idea either - if he's the same chap that's been helping throughout. You need someone who knows LRs and can spare you half an hour.

when i said get a second opinion i was being polite, even if you dont know land rovers ..i dont..but a lot of mechanicals..are ...mechanicals and this guys mechanic to be honest aint got a clue..hope thats not to impolite

I could tell! It was you that prompted me to chip in!

its a situation where you can spend a fortune on blind faith...by relying on some ones word who may or may not have the foggiest,

only change the drive shaft if you can actually see it has an issue, you may have a few coincidences or one buggered engine ,trying to turn engine over by hand might show whether engines tight or not ,loose pedal means little

i think the main clue is that it was stated 2 out of 4 cylinders has black plugs ,so poss no compression , now while electrics can cause no spark to happen on 2 side by side cylinders in the context of the breakdown as in oil light on...wouldnt to me point to drive shafts, or gearbox or leckys

there doesnt seem to be a main clue just a collection of different faults,without more info and things ruled in /out

he did say straight after he took plugs out and 2 were black..now what evers gone wrong..driveshafts ect..dont cause that
ive advised compression test..if it turns over, maybe screw a oil gauge into block while its cranking..
but most of all a new opinion

no but could be a collection of issues with some not causing current problem,how difficult is it to try and turn engine over by hand ,at least you know something then,it may just be a flat battery poor connection etc
