Offroad-Express

Its an old mitsi 2.7 non turbo diesel 4dr5 vintage 1980, when starting lots and I mean lots of white smoke out the back but only when cold, runs great when going.
I replaced the glow plugs pre quake in june lol, am guessing and thats risky, it's the fuel pump maybe out of ajustment ? or is it worse like re kitting seals etc.

Weed out the dribble and try a few things.
Don't discount the glow plugs, pull them out or test each one in place. I have known of them to crap out fairly quick.
Could be injectors, fuel pump (not that likely), compressons, manifold heater (if fitted), could be head or gasket. Some simple methods of diagnosis should nail it down.

Cheers,

check the glow plug timer,mite not be working or staying on longer enough.

thanks guys all the info helps, one mechanic suggested rebuilding the fuel pump and working back from there that was going to be an expensive day

Think it through mate, never a good option to just start rebuilding everything and see if it helps. Do your homework first or small problems can cost heaps

Something to try is double or triple glowing it when cold before start up,it makes the world of difference on my L200 even with new glow plugs

The 4dr5's need heaps of glow in my experience. Wont start without it.
My old Cruiser diesel blows white smoke on cold mornings. I put it down to condensation in the exhaust.

White smoke is water somewhere.

in the next week ill get an auto sparky to look at it, thanks guys the advice here is way better than some of the mechanics I've talked to

Or unburnt fuel when cold.
Ever thought an injector/s could be leaking?
Pull off the exhaust manifold and start it, see if any excess smoke comes out what cylinder.

Is it auto or manual? Transmission fluid also burns white

Awesome!!!!!

Care to explain how the transmission fluid could get burnt in the engine??

Sure thing:
If its an auto the rubber diaphragm in the vacuum modulator can fail which draws the transfluid back into the intake manifold. It about a $15 fix.

Yeah a leaking injector or one thats stuck open will cause white smoke. The injector will leak into the cylinder and on the exhaust stroke pump the diesel into the exhaust manifold. Coolant entering the cylinders will cause white smoke or steam (this may also bend conrods if it gets bad enough). I've seen some with a failed head gasket leak coolant into the cylinders over night. Like tomsoffroad said, condensation in the exhaust will do it too. Does it use any coolant? Check the simple things before spending big $ rebuilding pumps etc.
