Well reading your last sentence you may be on the wrong site ? :vb-jester2:

The Disco 1 does pretty well for lack of rust in the important bits, whereas as Series, particularly a Station wagon, has a lot of bodywork structure that will be showing it's age. Some of it complex to repair. However given the choice I would be repairing a Series over a Disco', but that is my preference.
Less there mechanically/electrically so less to go wrong ...

You cant weld the body of a Disco 1...

In that case should I skip the compression test and just start swapping bits?

Here you go again skipping steps

LetsHopeItFits said:
If its got low dry compression but good wet compression because the bores are bad, what can I do about it, short of getting new sleeves/liners installed, full rebuild etc.
In other news, someones just offered me a tempting deal on a 109 S3 5 door...

Thought thats why you skipped all the advice in the first place and went and brought another Disco for its engine

Its not normally the OP that wanders off the thread topic but you seem to manage it every time.

I do have to, for the sake of accuracy, say that this depends on which part of the Disco 1 needs welding.
My Disco 1 needed welding over the rear wheel arches and it now needs extensive welding to replace sills and bits of B posts.
I have already bought the repair panels.
All is in steel.
"That uniquely-shaped body uses many aluminium alloy panels supported on steel structures with steel inner wings. So, expect the usual galvanic corrosion between dissimilar metals. But even without that, the aluminium and steels are very capable of corroding on their own, especially the inner sills and underfloor and the load space floor, all of which need close scrutiny. Rusted sills and floor can be very expensive to restore properly.

The steel chassis (not to be confused with the Discovery II’s reputation for falling out onto the road) is relatively long lasting but, given these trucks can be up to 30 years old, it remains important to expect corrosion problems."

From https://www.landrovermonthly.co.uk/articles/how-to/how-to-assess-a-discovery-1/ that the OP might like to read.

So yes, you are not wrong the body per se is in aluminium, but it can all be fixed if you are prepared top do the work.

Yes!
If the pressure then rises it means that the bores are worn, if they don't and it is down it means either you have a head gasket problem or a valve/seat is worn/burnt away.

Not just worn bores, could be worn or damaged piston rings

Or just glazed bores which a hone & set of rings will cure.
Hope you're keeping well Stan.

Don't understand what is going on here, :vb-banana:

,

Even if it down on compresson on a few cylinders it will still run, fact.

Does it have spark?
Does it have fuel?
Is the timing correct?

So long as rods aren't hanging out the bottom of it, she'll run with all 3 of the above..

Easy start is 'erm... the easiest tell tale, there are misconceptions of the damage of easy start, but to be honest it's all bull so long as its sprayed in whilst the engine is cranking, give it a whiff and see if it catches..

Sorry of course you are right, but that often manifests itself in other ways, eg noise!
whatever the cause, he'll have to take the head off and have a good old look!

Thing is Henry, we have all been down this route to help troubleshoot the OPs problem but it gets sidetracked.

I am sure it could all be checked and fixed pretty quick tbh.
but, you can lead a horse to water,

Yeah, some people thing of them as aluminium body cars with steel chassis, which isnt really the case. Its a steel car with some aluminium pannels (doors, bonnet, boot, wings etc) but the roof, floor, arches, firewall, bits of the doors etc are all steel

LetsHopeItFits · Nov 5, 2023

Yes yes. Ill get round to it soon. Im either busy, or its raining. (It being november in north wales, you can imagine how often thats the case)
Its not raining right now, but Im supposed to be doing a uni assignment. Oh how wonderful a distraction a forum can be!

Shedload · Nov 5, 2023

I'm 59 and work full time. Not my favourite pastime but I've lost count of the number of times I have been out in the rain working on whatever.
Many on here will be the same. If it needs doing, crack on.
Not pleasant doing it but feel good when it done !

LetsHopeItFits · Nov 6, 2023

Just hypothetically internet wasting here - if I wanted to, could I fit a 200tdi to my disco as easilly as a 300tdi?
Alternatively, can I put my facelift dashboard and interior in a 200tdi, including the adjustable steering wheel?

Awesome, thanks. Ill bare that in mind

Compression tester should be here soon.
If its bad news, have I got to take the engine out to hone the bores and fit new piston rings, or can it be done with the engine in place?

kermit_rr · Nov 9, 2023

Let's get past the first check first.. I'll bet your compression is ok

I hope your right. The wet compression will definately be fine.

Its broken.
