old rings in new pistons?
okay so i had one of the pistons get damaged due to timing belt failure, so i ordered a new set, my mechanic said to use the old rings which had less than 1000 miles on them in the new pistons as it will save time from breaking them in and it would be perfectly fine.
now when i start the car up after it gets warm, there is white smoke coming from the exhaust, now i dont know weather its due to the older rings being used in new pistons or my turbo going out because a piece of valve went into the turbo due to the previous failure.
now what i wanted to know is, can the older rings, which have only 1000 miles on them be used in the new pistons or i should replace them with the newer ones?
and is this the cause of the smoke? or maybe something else?
thanks,

White smoke is coolant. Nothing to do with rings...
"Old" rings on new pistons is fine, as long as you used the same piston (manufacturer and bore size). Especially with that low mileage.

the manufacturer and the bore size are same, just the design is diffrent from previous piston, but the rings are same.

Burning coolant indicates either a head gasket that isn't, a cracked head, or a cracked cylinder wall. So, it is a problem that needs to be solved.
You should be able to smell the difference. Burnt oil smells gross. Burnt coolant, while still kind of gross smelling, still smells mostly like coolant still since its technically not burnt, its just been turned into steam.

it doesnt matter now, its been done. If it was me unless you are trying to save every dime, I would always put new with new.
You'll need to trouble shoot your white smoke, check compression, loss of water, head gasket, steam or smoke etc. Usually oil will push into radiator due to pressure but when you are motor off, water will then leak back into head via blown head gasket or crack, then you start up and hence steam coming out...

i cannot trouble shoot the rest now because the turbo is out of the car for repair, when everything is hooked up, i'll check the rest.
although i think i know what the problem is, i just read that if you have a 4g64 block you need a adapter plate for the water pump, which obviously the mechanic didnt know about and he installed it without the adapter plate. i have a 2.1L.
but the thing is, its not leaking? shouldnt water or coolant leak when you dont have an adapter plate?
i just hope that its the water pump adapter problem, and i dont have to pull off the head or change the rings.

maybe it could be the head, as i bought a used one.
but im leaning towards the adapter plate for the water pump not being installed, as i have a 4g64 block.
i will report back as the car gets ready once again.

the head gasket and head studs are brand new, the block is a buschur built with just a 1000 miles, only one piston got damaged from the top, rest was fine.

Water pump plate won't make it smoke form the exhaust. You would just have a massive coolant leak from the water pump are that would occur as soon as coolant go to that level in the system...
