ditchman Posted September 18, 2015 Author Report Share Posted September 18, 2015 Probably starting up then just wailing it down the road does most harm to them, block hasn't had time to warm through. We rebuilt a few Land Rovers when I had the bigger unit, we had a chassis change down to 3 days That was remove it and refit it after galving, not counting time to prep for galv. Think it would knacker me now working like that Last motor I built was the Suzi trialler, that was a GOOD motor, very effective. right you've in your time have meddled with a few landrovers in the past.....whats your view on removing the thermostat ?..................a lot of people do...i have never... ,..........

rodp Posted September 18, 2015 Report Share Posted September 18, 2015 Should be no need, warm it up gently. Remove the stat and I would think you're messing it up, making it worse. When they designed (came up with) the TD they obviously tested it to destruction, just not as much as Joe Blogs, the idiot who starts from minus ten then blasts it up the steepest hill he can find to get the heater warm. I'd leave the stat in, treat it gently (it used to be called mechanical sympathy) and keep an eye on the gauges. When I started driving many moons ago, especially hgv, this is what was expected of you. When turbo's came out you started the engine at tickover, left it running a few minutes for oil to circulate then drove off steady until warm. When stopping you did the same, pull up and leave ticking over so spinning turbo had oil while spooling down then turned it off. If engine was very hot (overheating) you ran at fast tickover until normal then turned it off. never start and thrash, and never just turn off a very hot engine (it boils the water away from the head) Bear in mind I did my time served truck mechanic in the seventies and trucks were primitive compared to today. Head gaskets were routinely changed, heads were skimmed regularly, drivers were given a boot up the *** daily for being total numpties Quote Link to comment Share on other sites More sharing options...

I reckon not many. I think it was 3 years but haven't checked. Bet they didn't sell many after the first 12 months though.

archiebald Posted September 18, 2015 Report Share Posted September 18, 2015 my 2.5 td had done 198000 miles when i removed it! so good going really.i only removed it as it leaked oil fromrear main seal after severel goes at fixing that i swapped it for a 200 tdi 86 to 89 apparently https://en.wikipedia.org/wiki/Land_Rover_engines#Diesel_Turbo_.28Engine_Code_19J.29 yes mine was 1987 the main thing i miss about that engine is the sound!

ditchman Posted September 18, 2015 Author Report Share Posted September 18, 2015 i have heard of loads of landrovers...with the 2.5 n/a that have done over 200,000 miles with just regular oil change ...timing belt done and a set of new nozzles............there is an ole boy in Brundall (next village)...that has a seris 2 i think...with a capstan on it he has had it from new and uses it every day....he earns a few quid as a local courier !!

ditchman Posted September 18, 2015 Author Report Share Posted September 18, 2015 i cant wait to see this engine built up - will you do a video of it running? i will "run it up dry" for max 10secs....with the timing cover off...will do a vid but i will have difficulty posting it i think........

archiebald Posted September 18, 2015 Report Share Posted September 18, 2015 I was told the shells where worn on mine so the crank can "oscilate" slightly and allow oil past the seal? I dunno how true this is! Quote Link to comment Share on other sites More sharing options...

I dunno how true this is! if the shells were that worn you would hear it as a deep knock....and it could quite possibly let oil thro the rear seal.......

Used to work on a couple of disco's two that come to mind 400+k and 250+k, 200 TDI's just regular servicing and the odd head gasket due to the gasket giving way and loosing compression to the atmosphere at the rear of pot 4, still pulled well and little smoke, both working vehicles.... body's rotted away!

archiebald Posted September 18, 2015 Report Share Posted September 18, 2015 (edited) if the shells were that worn you would hear it as a deep knock....and it could quite possibly let oil thro the rear seal....... It was leaking through rear main seal and I thought same. I paid a garage to do it in the end and it still leaked! And they told me bottom end bearings where worn..... So I did a 200tdi transplant and I had the same garage do the timing belt on my 200 tdi as I Didn't have time to do it myself and it snapped after 200 miles. Makes me wish I kept the 2.5 td and still able to use a classic car policy at £90 for the year!

rodp Posted September 19, 2015 Report Share Posted September 19, 2015 My last Disco (300tdi) had done 250k or near enough when some wassock decided to do a U turn in front of me. Lovely motor, ran like a swiss clock. It's replacement 300, bought in a rush as a temporary motor, has done 100 and something k. It runs great but just can't take to this one. Going to find another then sell this. Quote Link to comment Share on other sites More sharing options...
ditchman Posted September 19, 2015 Author Report Share Posted September 19, 2015 Starting to take the valves out and check the seats ...which dont need replacing as they can be lightly refaced then the valves lapped in......a "ghostly " face appeared............must get the vicar to exorsise the engine before i put it in...so it dosnt frighten itself to bits..........when i finish taking the valves out...i will take it up to Cromer for pressing and refacing..................

ditchman Posted September 19, 2015 Author Report Share Posted September 19, 2015 the "mouth" of the ghostly face is the precombustion chamber....the end of the injector nozzle sits there next to the tip of the glow plug then the whole thing is capped off with the "hot spot insert"....which has a number of nipples inside it which glow red as the engine is running to aid faster combustion (expansion)....similar to a model aeroplane glow plug engine..........

ditchman Posted September 19, 2015 Author Report Share Posted September 19, 2015 The first pic is of the sequence of the........ injector injector nozzle injector shoud...(this protects the body of the nozzle from excessive heat and also completes the conical shape of the combustion chamber heater plug (for cold start) hotspot cap the second pic is of the inside of the cap showing its glow nipples.... this engine is termed as "indirect injection"....as the expanding fuel enters the head and combustion chamber first whereas more modern enjines are "direct injection"....the combustion chamber or sometimes referred to as the "swirl chamber" is now in the piston crown with the inject going straight thro' the head into that half egg shaped recess in the top of the piston................ hope i am not boring you ...
