Hi Guys,
I need some help troubleshooting a problem. My Defender '95 300TDi is smoking... Sometimes is has a blue-ish hue which would indicate that oil is getting in the combustion chamber somehow. On other occasions it's more white... but in all instances it's early in the morning or late at night when the engine is cold. Once the engine warms up it tends to pretty much disappear. However, the engine feels lethargic and does not run as fast as it used to.
Now, I recently had the timing belt changed and it was after this that I started having challenges. I checked the oil and it was dirty so I changed it and the engine ran a little cleaner but it still smoked, added some diesel cleaner to the tank for good measure... I also changed the glow plugs and the glow plug relay but still no change.
Here are the checks I made this morning:
1) Check turbo
Turbo felt ok but was difficult to gauge as I don't know how smooth to was supposed to move. Tried to rock it back and forward and it was pretty sturdy. Crud was in the hose that connects from the air filter to the turbo.
2) Valve stem oil seals
Tested on ascent in 2nd gear to see if under load it would cause it to smoke but it didn't.
3) Checked for soot in tailpipe
Yes (How much is alot? As it's by no means blocked - that I could see)
4) Crankcase breather pipe
Was not sure how to clean or remove so did not risk (is the same thing as the breather cyclone?)
5) Hoses
Ok for the most part a bit worn but no leaks or cracks that I could see
6) Oil levels
Oil was changed three days ago and has not dropped... it still looks pretty clean also.
7) Injection timing
I've read that if the injection timing is off it'd run with white smoke... however my landy only smokes intermittently seemingly after I've been idling.
Any suggestions?
