JimAttrill Posted February 17, 2008 Share Posted February 17, 2008 Looks like worn bores. You will be looking for an engine overhaul or at least a rebore. Best to buy a second hand 200tdi out of a rusty mot failure disco and fit that. Quote Link to comment Share on other sites More sharing options...
tjolliffe Posted February 17, 2008 Share Posted February 17, 2008 Yea I agree with Jim, 2.5 N/A's and TD's are prone to wearing and thus burning oil. It will run fine but do keep and eye on it and replace air filter regularly as it will get contaminated with oil. In the long run as Jim suggests you will probably need to have the engine re-built or stick a 200tdi from a discovery into it. It's a very simple conversion, there are loads of threads on it and it can be done with relatively little mechanical know-how (just so long as you persevere with it). Over here it works out about £500 - £600, not sure what that is in euros , it makes a massive difference to performance and reliability. Hope that’s of help Cheers Tom Quote Link to comment Share on other sites More sharing options...
Ex Member Posted February 18, 2008 Share Posted February 18, 2008 Most likely the timing is simply retarded. Blue smoke on a diesel on overrun happens when the timing is retarded. Adjust the timing and I bet it is all better..... Engine oil consumption does not give blue smoke on a diesel, that is for petrol engines. On a diesel, blue means unburnt fuel or oil. This can only happen if the fuel is injected too late or if it is getting in after the cylinder such as exhaust valves or turbo seals. However, your description of smoke only on idle and overrun is exactly what happens when the timing is retarded (injecting too late).

wadey Posted February 21, 2008 Author Share Posted February 21, 2008 Great thanks for the advise will obviously get someone to check out the timing first , then if not look out for a throw away disco 200 tdi, which I was thinking of looking in to at a later date , plenty of uk reg cars practically given away out here!

Les Henson Posted February 21, 2008 Share Posted February 21, 2008 Nice links Luke and entirely correct. Les. Quote Link to comment Share on other sites More sharing options...
Ex Member Posted February 21, 2008 Share Posted February 21, 2008 Don't believe everything you read on the internet. Is it consumming a lot of engine sump oil??? If not, I'm right....... Go out and retard the timing on a 2.5TD, go on..... see what happens.... Tons of smoke at idle and on overrun, just like the OP says is happening.

wadey Posted February 25, 2008 Author Share Posted February 25, 2008 thx again for the advice all!!, naturally i'm going to check the timing first!, no evident oil loss since oil change a couple of months ago, is the timing on a diesel something for a mechanic?, or something a fairly competant diy mech like myself could undertake!, havent dissed the other advise of more major engine work yet !cheers Wade Quote Link to comment Share on other sites More sharing options...

You can buy these from a few places, or find someone local. However, with these pumps, you can just advance it a little and see. Scribe a line on the pump and timing housing, so that you know where you started. Loosen the pump bolts a little (3 on timing housing and one at back of pump). Rotate a couple of mm (counter-clockwise as viewed from the front of the car) and tighten up. If it is too advanced, you will hear excessive pinging under load and it will not want to rev as freely. Just be carefull and adjust to what seems right. If it is too advanced, it will be hard on the engine. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted February 25, 2008 Share Posted February 25, 2008 In order to get the pump timing back to the factory setting you really need the timing pin that screws into the pump body. You can get it pretty accurate by trial and error though. I just takes a bit of patience. Les. Quote Link to comment Share on other sites More sharing options...
RRX Posted February 25, 2008 Share Posted February 25, 2008 Might have to have a look at my timing as i have the same symptoms with some blue smoke on idle and lots on overrun. but i would be more inclinded to say worn stem seals or turbo seal as its a 170k engine Quote Link to comment Share on other sites More sharing options...
Speedy_Gonzales Posted February 26, 2008 Share Posted February 26, 2008 Might have to have a look at my timing as i have the same symptoms with some blue smoke on idle and lots on overrun. but i would be more inclinded to say worn stem seals or turbo seal as its a 170k engine I have similar on cold startup of my TD5, blue smokes a little and then is fine... Is this likely to be oil ingress through valve oil seals? Its done nearly 150k... Jamie Quote Link to comment Share on other sites More sharing options...
