Hi all,
I have a defender 200tdi with original engine. c 190K
Got some blue smoke then lots of white smoke close to home.
When I pulled the head off the No:1 glow plug took about half an hour to remove. It was stuck pretty well in there with black carbon depositson teh sides.
No:1 piston was soaked in water too so assumed gasket failure near to that piston.
So replaced the gasket and checked the head for distortion there seemed to be none as it did not overheat so cleaned it up, lapped the valves replaced the caps & the valve retainers and the valve stem seals and reset the tappets.
No:1 pushrod was also very slightly bent so that was replaced too.
Reconnected all the pipework and pumped the diesel till it reached the spill rail.
Tried starting it up but was very difficult but eventually it started - water was dripping from the exhaust for a while and grey smoke but not too bad.
I took it for a short run to clear whatever crap might still be in the exhaust system and after it warmed up - no more smoke at all while running in high or low revs in any gear.
Today I tried starting it up and had to hand pump the diesel through again to get it to start.
It eventually reluctantly started and was smokey - grey smoke.
so went for a longer run and the smoke cleared once it warmed up.
I have noticed that the No1 glow plug is leaking what looks like watery oil near its thread and i thin the water level had dropped since yesterday but thought it might just be settling after the run so i will double check that tomorrow after I refill.
I am also checking the fuel pipes for leaks.
Logically I am assuming that the head gasket is good since it reaches temperature at which point the slight exhaust smoking ceases completely!
If this were not the case then smoke even after running temperature was reached.
I would like to know whether the water jacket or oil ways in the cyl head pass near the glow plug and would I be right in assuming that I do in fact have a cracked head in an unusual place ( i did visually check!)
Sorry about this being a long post !
any advice would be gratefully accepted - thanks
