Reading the blurb, it goes in the cooling system so is probably ony for sealing leaks involving water. If it is just an oil leak then fixing leaks in the cooling system isn't going to be of much use.

hhhmmm it just confused me the way it says for blown gasket, mechanic said there is a small hole at lower back of engine  :x (just above the gearbox) where the oil comes out but only leaks out when hot i just trying to find an alternative to paying 800 for head gasket and cam belt to be changed! option i was considering was drop a v8 lump in it  :dance: but dunno how hard itll be and how much electrics need to be changed. do you reckon that an easy job? thx m8

I have to say that sounds a bit more involved than a blown head gasket. If you can get a good V8 for sensible money and don't mind having the car off the road for a bit I'd be inclined to do an engine swap, the MPI was never really up to the job.

You may need to do some nifty work to hook up the ECU assuming you fit an EFI V8, but I bet several people have done it before. Anything is possible with these vehicles, you just need to figure it out!

not sure if i would go efi i prefer the twin carbs more hassle i know but my old one was so reliable. just gotta look for a donor vehicle  do u know of any?

[Disco Matt]

You might well find a V8 Disco with a good engine on ebay if you have a nose around - there seem to be a fair number of people breaking them for spares now. You could get any other parts you need too that way.

I think the MPI had oddball gearing? Not sure but have a suspicion it was lower geared than the TDI or V8?

V8 Disco's are ten a penny i'd bin it and buy another Disco..... 

[morson4x4]

Yeah the gearbox is a high reving with long time before needing to change  i would buy a new one but the missus likes the shell of this one typical woman  :dance:

[Disco Matt]

I've often wondered if MPIs would tend to be tidier than other Discos of the same age - if you think about it they wouldn't have been bought for heavy towing or off road use.

It sounds as though you'll need to swap the gearbox or diffs, depending on which part it is that has the altered gearing. Your fuel economy with the V8 would be terrible otherwise!

[morson4x4]

well i decided to get a v8 engine and gearbox i prefer the carbs but efi ok, or find a cheap donor vehicle that not road worthy and pinch the v8 out of it  :dance:

Just a bit of info on the the MPI, The transfer box on those has slighly lower gearing making it ideal if your planning on fitting massive tyres. If not it'll be worth flogging as it will fetch a preimium price.

[morson4x4]

if i do drop the v8 in will i have to change the transfer box

is the 2'0 a t series or m series ?. i used to work on rovers and the 2'0 t series used to leak think it would be the passenger side rear corner in a disco . there was a modified head gasket . there were fairly easy to do . alan...

[ben_haynes]

what age is the disco as it may have to comply to emmission Regulations and would need to be an EFi with lambda's and Cat's if it is pre 1993 you are ok if not it needs a Cat and Emission regs are tightened

sorry to put a downer on things

[morson4x4]

it is a 93 mpi i think hate to say it weigh it in ashame really causes its in mint condition i found a 300tdi R reg 97 for 1k was stripped of offroad bits (wantecd 2k with bits) so i can start from scratch  :dance:, so if any 1 wants to make offer on disco pls feel free   [-o<
