Sprocket Posted February 7, 2010 Report Share Posted February 7, 2010 Depends on what engine it is, Niss, Mitsu, Toyo? Are you sure its a cracked piston? Majority of cases with piston removal will mean removing Cyl head and Sump / draining oil. Quote Link to comment Share on other sites More sharing options...

ST3V3 Posted February 7, 2010 Report Share Posted February 7, 2010 head gasket gone or cracked in my opinion I had a disco that ran on after ignition turned off sucks engine oil into the cylinder and runs on that Quote Link to comment Share on other sites More sharing options...
crazyfarmerboy Posted February 7, 2010 Report Share Posted February 7, 2010 i am afraid to tell you that the land rover 2.5 turbo diesel is not a great engine, they are prone to cracking in the block, would not be a huge job to change it for a 2.5na or a 2.5tdi if you can find a defender one for a good price, putting a disco engine is a bit more difficult, Quote Link to comment Share on other sites More sharing options...

You're right though, the 200tdi Defender should more or less drop in. You can squeeze the Disco version in but I'd go Defender. Quote Link to comment Share on other sites More sharing options...

Paul223 Posted February 8, 2010 Report Share Posted February 8, 2010 seals gone in your turbo mate its running on its own engine oil fed in through the turbo mine did it once 1st gear low box it was a nightmare to stop it got the brakes a bit warm aswell put a disco 200tdi in it shortly after they usualy go nuts after sitting ticking over for a while then first dab on the gas and it all goes a bit mental smoke knocking e.c.t. I'd agree, rule the above out by disconecting the inlet manifold hose between the turbo and the inlet manifold and then give it a run. If the turbo seals are goosed it'll throw oil out, run on and smoke like you not seen before Disco/90/110 200tdi is the dogs dangles for the job, well worth the effort Quote Link to comment Share on other sites More sharing options...
lister1 Posted February 8, 2010 Report Share Posted February 8, 2010 yep running on it's own oil. proably turbo gone as said before. it maybe worth seeing if you can get a cheap turbo to replace it but with second ahnd parts you nevere know what you are going to get. i've got a 1985 lr 90 was a 2.5 petrol now a defender 200tdi engine. the defender 200 is a straight swap but you pay a bit more for a defender angine. a disco 200 is nearly a straight swap abit bit of messing around with the exhaust but you can pick up a mot failure dico for a few quid then break it down sell any bits you don't need ie axles garebox then scrap the shell and you end up getting a free engine. cheers lister.

goldypurple Posted February 8, 2010 Report Share Posted February 8, 2010 I see your in Norfolk. As others have said, it running on it own oil, which is quite common with that particular engine. my advice would be to put a 200tdi engine in it you wont regret it, once done Try this guy, his name is richard, very good and reasonable, he can supply and fit the engine, or may be able to help you out with the old one http://www.glencoyne.co.uk/ Andy Quote Link to comment Share on other sites More sharing options...
