is the block of a 2.25 petrol the same as a diesel??
johnpirate:
I know of at least one member of the series 2 club who when their diesel engine died. They used a petrol block and built a diesel with it using second hand bits it ran for 10000 miles plus not bad for a weekend dodge to keep the vehicle on the road.

Unless you do a lot of miles stick with petrol, they are so much more reliable.

Hmmm :)
My list of engine spares if I go on a long trip in the diesel.....
1 x fanbelt
1x alternator if off roading
fuel pump
fuel solenoid
oil
Water
needed a fanbelt once in 3 years
Diesel... give it fuel and energise the solenoid and it runs and doesnt stop until you de-energise the solenoid.
My list of spares if I go on a long trip in the petrol 2.5 series 1
1 x fanbelt
4 x plugs
1 x points
1 x condensor
1 x dizzy cap
5 x plug leads
1 x coil
1x rotor arm
fuel pump
WD40 lots of :)
1 x alternator (as above)
Oil
Water
Petrol...give it fuel and it will run...as long as your plugs dont 'go duff', leads dont track, dizzy cap doesnt track or carbon brush crumble, rotor arm foul (easy fix though), points dont burn out, condenser doesnt fail, coil doesnt give up etc etc :)
The only other real mechanical issues are common to both engines so no difference....
both engines use a starter of the same basic design so no difference in reliability there,
both use a lift pump of the same design so no difference there
In fact the only real difference is that a petrol has numerous short lived electrical components neded to make it run whereas a diesel has none bar a stop solenoid
Diesels may be slower and noisy but bar a major mechanical faux pas they are as reliable as it gets, far more reliable than any petrol I've ever owned and run on veg oil to boot :)

But will a diesel continue to run with one smashed piston and three good ones? ;)
The items that you say there could easily be said about the injectors too! After all, they don't last forever and neither does the injector pump. Or what about an air leak in the fuel line? A petrol will run, but a diesel won't under those conditions.
...and WD40? Why why why? I have not yet experienced a problem with my engine cutting out from water splash and I've gone pretty deep sometimes (bow wave above headlights). :-.
I'm on the petrol side of things for reliability. Particularly after when my head gasket blew and it continued to drive the final twenty or so miles with only two cylinders actually firing properly (gasket blew between 2 and 3). :dance: I'd like to see a diesel do that. :P

A smashed piston... thats a bit random its not an everyday reliability problem is it :) smash a piston on either and your in trouble with bore damage, crank journal probs etc etc
you are clutching at straws mentioning a fuel leak...yes a diesel may well run with an air leak..granted badly, as will a petrol drawing air in, in fact the petrol will then run way too lean and hot poss resulting in a piston melt... I could have also added a diesel wont burst into flames with a fuel line leak again we are talking day to day reliability so fuel issues again apply to both??? and as for injectors and pumps well what about the zenith issues.. Ive only listed issues pertinent to the particular engine fuel type I could go on all day pointing out 'common' issues to both types..that would be pointless as it cancels the comparisons out..
you may have never had issues with water on a petrol ignition but thousands have, just go to billing and see how many are dead and being WD40d all round the course (they are all petrol by the way :) )

I'll chalk that random comment down to your inexperience with diesels otherwise you would know that of course a diesel could run with a shot gasket (dependant on the severity)...again the issue affects both, the last diesel I saw doing that had blown the gasket and warped the head to such an extent the water tank blew due to overpressure. but the engine still ran and drove, take the head off most TDs and you will find several cracks between the chambers and the owners wont have even realised.......and the TD is poss one of the worst diesel lumps landrover ever used (it was after all only a stop gap engine)
reliability issues are generally an issue that can be attributed across a common range... neither diesel or petrol landies suffer smashed pistons regularly across the range so lets keep things realistic :)
I am sure given a few years with landys you will encounter many issues I certainly have and have only been playing in Landys for a mere 27years and have seen first hand all the issues I have listed...so am talking from first hand experience.. gotta admit prob done 1/4 million Landy related miles in everything from a series 1 (one of my current landies) to Wolves on a regular basis and Ive never smashed a piston :) , lets be realistic with reliability issues anybody could pull up any number of totally unlikely problems :)
