carlosbeldia Posted April 18, 2011 Share Posted April 18, 2011 A man who I just met told me that his 2286 diesel used to be a gasoline, he only took out the spark plugs, timer and other parts and replaced them with diesel parts..... is this possible?

Gazzar Posted April 18, 2011 Share Posted April 18, 2011 Well, Sort of. The other way is easier. You'd need to change a LOT of parts. The block is common, I think, and the diesel crank is ok for a petrol. But you'd be changing everything else. Head, crank, pistons, cam (I think), and timing gear would be advised. Why not try it and see how you get on, post up pictures as you go! G. Quote Link to comment Share on other sites More sharing options...

Phil Hancock Posted April 18, 2011 Share Posted April 18, 2011 From petrol to diesel the only parts that you can reuse are; block, oil pump, sump, timing case, timing chain/sprockets/tensioner set up, cam followers, water pump, crank vee belt pulley, oil filler tube, dipstick and tube, thermostat & housing.

The head is the killer - the diesel head is very different, there are pre swirl chambers and hotspots, not to mention the glowplug holes! And, at the end of the day, the diesel isn't all that great - it was quite low powered, compared with the petrol. Quote Link to comment Share on other sites More sharing options...
Gremlin Posted April 19, 2011 Share Posted April 19, 2011 Petrol crank will not work on a diesel (it will break) as its cast while the diesel is forged. But if you have enough money then yes it can be done! G Quote Link to comment Share on other sites More sharing options...

But if you have enough money then yes it can be done! G Just out of curiosity, what is the difference between the two? I understand that the cast means that liquid steel is poured into a mould, but what does forging a crank involve? Is it drawn steel pressed into shape whilst hot? G.

Phil Hancock Posted April 19, 2011 Share Posted April 19, 2011 A petrol engine cast crank is cast from cast iron of a grade known as 'SG iron'. Castings have a granular consistency to the metal. A diesel forged crank is drop forged from steel. Forgings have a grain that follows the shape of the finished artical and are a lot stronger than cast. Casting is pouring molten metal into a mould that is the shape of the required artical. Drop forging is basically pressing a chunk of almost white hot steel between 2 dies(moulds) to produce a piece of steel the shape of the inside of the dies.

carlosbeldia Posted April 20, 2011 Author Share Posted April 20, 2011 I'll explain why I want to do this change: In Colombia, I haven't heard of more than 5 cars with LR diesel original engines. If you find one of these engines, you can count for only the engine, as far as 3000 pound of cost, so whatever it costs are involved in UK, they are sensible cheaper than a Colombian one, not even thinking yet in these are new parts vs 40 year worked ones. Due to high prices of gasoline vs diesel (about 30% higher, not counting the lower consumption), it's a really good inversion. And finally, as my Series are only for off road, I really prefer a diesel engine that doesn't go down when things go wet..... for travelling and everyday use, I have a 110 TD5, so it's not a problem the additional smoke or noise. As far, I have checked following parts that must be changed: Valves Guides Valve Rockers Pistons (and rings set) Con Rods Cam Push rods Starter engine Cam bracket (somebody can confirm me if there is one or two of these?) Injectors Gaskets Admission By LRseries, costs are until now a healthy GBP 500, not looking yet for option prices. Major components, diesel pump and head (are you sure crank must be changed?) I'm trying to find some in good conditions. I saw one 2286 with a Nissan diesel pump working better than with the original. They are cheapers and easier to tune, what do you think? If I let the gasoline crank it's sure it's going to break? I'm not a high rev driver.... The other option is going for a 5 bearing engine, so I can use the head with no problem, I'm looking for one... Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted April 20, 2011 Share Posted April 20, 2011 Yes you need to change the crank, the petrol one will just snap as it is not designed for a compression ignition engine. Quote Link to comment Share on other sites More sharing options...
carlosbeldia Posted April 20, 2011 Author Share Posted April 20, 2011 Thanks Bowie. How much do you think it can cost? I haven't found the diesel hed neither the diesel pump, can anybody guide or referred me? Quote Link to comment Share on other sites More sharing options...
TheRecklessEngineer Posted April 22, 2011 Share Posted April 22, 2011 2286 diesels are cheap here in the UK (<£100). I'd be looking at getting an entire engine shipped over. It would save you a lot of hassle! Quote Link to comment Share on other sites More sharing options...
carlosbeldia Posted April 22, 2011 Author Share Posted April 22, 2011 Problem is here in Colombia we can't import used engines or cars.... Quote Link to comment Share on other sites More sharing options...
Gazzar Posted April 23, 2011 Share Posted April 23, 2011 Oh, goody, import regulations! We can get around those, tell me, are secondhand parts subject to the same regulations? Reason I ask is I've a heap of old diesel engines and I could strip one of them and stick the parts on a pallet for you, if you wanted. The only thing is the exhaust manifolds are not for sale (they can reach big money in the UK for some reason!), so you'd have to manage that on your own. G.

carlosbeldia Posted April 23, 2011 Author Share Posted April 23, 2011 Hi Gazzar, no, second hand spare parts are permited (I can bring them as spare parts for a classic car)..... it will be a really giant help if you can do that. How much for two of them? please write me to carlosbeldia@yahoo.com to set things up..... Quote Link to comment Share on other sites More sharing options...

lexi Posted April 26, 2011 Share Posted April 26, 2011 5 bearing petrol have forged cranks as well IIRC. Quote Link to comment Share on other sites More sharing options...
carlosbeldia Posted April 26, 2011 Author Share Posted April 26, 2011 as far as i have understood, there is no need of changing head and cranck in 5 bearings, right?

Gazzar, I still haven't received your message, PM sent to your account... No idea what's wrong - email defeating me! Anyway - I've PM'ed you back. The head on a 5 bearing has to be changed if converting to a diesel, as there are no hotspots, and no hoes for the glowplugsetc. G. Quote Link to comment Share on other sites More sharing options...
Mike Brownlie Posted April 28, 2011 Share Posted April 28, 2011 why not look at a diesel engine that is more available where you are ? There are conversion kits out there for a fair few. Isuzu / Mazda / Daihatsu / Cummins. Quote Link to comment Share on other sites More sharing options...
