SMOKING SERIES DIESEL...Help

[Miniman]

Can you replace piston and oil control rings without taking the crank out.
I have this smoke problem and I have replaced the injectors thinking it was them dripping but its still smoking been getting worse over the last 3 months. I have had a play with the pump timing and to no avail. The only other things I can think are worn valve guides or oil control rings.
It Smokes more when its ticking over. When revved it puffs alot out then clears. But if I stop in a traffic jam after about a minute or so it starts again.

Any Ideas guys...

Yes but you have to take the head off, so as far as it goes you may as well do the head and valves as well

Its a ongoing thing really if you intend to do the rings, get the whole lot and spend a while to overhaul the lot,
Piston rings, check pistons
Crankshaft shells, check the wear and replace if in doubt
De glaze the bores, check wear, and any marks
Remove, clean check valves and seats, regrind if necessary, and fit new oil seals

Thats the basics but look round and see what you can see

You can also do pretty much everything while the engine is still in place.  The crankshaft only needs to come out when things like big end stuff needs sorting.

By the sounds, it is the valve guids leaking into the cylinders, as my 2A gets a big puff of blue smoke when firing up after having been driven a day before.

If it was piston rings at fault, it would be a more of a constant pouring of smoke throughout the rev range.

True about the shells on the crank, but after doing them on mine a few months ago, I managed to slide 2 out of the 3 main bearing shells out as well, the only one I couldn't was the rear one

All good advice. So The head off and the sump then the pistons will come out up top. Great dont want to be taking the dam engine and box apart again. Sick of taking all them dam bolts out awound the seat and floors. I may recondidtion this spare head I have. Then that means its only off the road a short while. Its my everyday car aswell.

Check out what I have just bought for pennys....

Worth picking up a cylinder honing tool, fits on a drill and does the job if the bores are glazed and polished
