it should be light heavy blue smoke..
what injun is it?
why did y'awl change it?
is it the smoke there all the time?

HI slob, answer to your queston.
the engine is 2 1/4 DISEL.
the reason for change, the previous owner had run it with a cracked head, the landy not his, and it had ceased.
oil sump was full of water pistern and bore shatered.

if its just on start up this int usually a problem , if its all the time it is.. it could be that you have oil in the exhaust pipe which needs to burn off? and i know from experience this can take some time. or maybe the injun you put in is ferked??,valve seals, rings, the usual crap

sounds like its running on oil, whu=ich basically means the rings are shagged, have you got a diesel compression tester

ah was just gonna ask, is the sump oil at the correct level?

hi.thanks for that.havent got compression tester,only running for half hour at a time dosent seem to be using any oil the engine seemed to be ok when took out of the other vechicle.

if you have too much oil in there it will get past the rings and produce blue smoke..

just asked,well yelled and he says theres not to much oil.

adjusted pump, the smoke as cut down there is no smoke on high revs.it only seems to be smoking when releasing accelerator.

If it is giving smoke on the overun as you say that is valve guides / valve seals.

The old tried and trusted way was to have a piston all the way down the bore, with the spark plug removed fill the bore with string then bring the piston back up the bore so that it holds the valves closed. with the rocker shaft removed you can then lever (with a suitably shaped tool) the valve down to remove the collets and valve spring to give access to the valve seal. This way does take a lot of time, i personally have never done it this way I have always removed the head and rebuilt everything properly.

I would defenatley take the head off and lap the valves wile your on.

Thanks..Ill give it a go after the weekend..pub first

have you any idea how long it was sitting around beore you got it? Mike

have you any idea how long it was sitting around beore you got it? Mike and how many miles have you done with it since fitting it?

The old land rover diesels will go on for years with the smoke, i have one thats pretty knakrd in my series 1! is a pig 2 start puffs blue smoke after about 30 seconds its all gone and pulls fine! You could just leave it and save yourself some work aslong as it not to bad!!
