Excessive oil consumption in 2.25 dieseal

...its getting through about 5 litres per 400 miles or so. No external leakage. Blue smoke in quite smokey exhaust...but only under load. Otherwise clear and pure exhaust like a mountain breeze. Very slightly slow starting developed. Any ideas? Ok silly question. Needs engine rebuild to fix what do you think? Or perhaps better to swap engines? Where to source good engine please? Its a cute vehicle that is admired and needs to be got 100% shipshape.

Rebore, new pistons and rings if you want to keep it original. I doubt the valve guide oil seals could be causing oil consumption like that. If you're not bothered about origionality then a 200 Tdi out of a Discovery, perhaps with the turbo removed, would be a good bet.

Hi. The (good) mechanic that did
the head gasket not so long ago
said the pistons and bores looked
ok. Has been said by another
good mechanic that piston rings
might be warn. I've changed a
petrol engine in another landy..is
this job within my capacity u
rekon? Might have some help.

If you can do an engine swap then putting some new piston rings in should not be too much of a stretch (as long as you have plenty of patience) as these engines are nice and simple. Just make sure you put covers on the inlet ports on the injectors and the outlets on the fuel injection pump to stop dirt getting in when you take the injector pipework off (make sure you keep that lot clean too) as the internals of injectors are very sensitive to dirt. Just follow the steps in a Haynes manual or download a manual from here:

Buying a piston ring compressor would be a good idea for getting the pistons back in without breaking the rings. You might as well take the valves out of the head, clean it up and change the valve stem oil seals while you're at it. You'll need a valve spring compressor for that. You'll need to get the head off before you order the rings to find out if you have oversize pistons (ie it has been rebored in the past). Good luck with it.

Thanks. The later pro mechanic
mentioned that valves
themselves mite need
replacement. I'm not 2 daunted
despite inexperience as there r 1
or 2 people i can call on 4
advice at crucial points. I will
have 2 construct an outdoor
shelter using plastic sheeting
with lighting from genny.

Might be worth getting your mate to measure up the bores to make sure that you're pistons are the right size and also to check that the new rings are the right size although you should be able to do that yourself if you follow the instructions carefully. Your mate prob has a bore deglazing tool which would be better than using sandpaper (protect the crankshaft journals while you're doing that as you don't want debris getting into the oilways).
