vt v6 lifter noise

[mr little]

hi there,
my vt v6 exec just recently sezied a motor, changed motor for a less milage secon hand motor, however there is a ticking noise as soon as i start it when its cold, it lasts about 5 mins till it starts to warm up, i believe it is a lifter because thats a common problem with the ecotechs, any ideas what it is or how to fix it?

As above, try some lifter free up additive first up. Id also give it a few oil and oil filter changes about 2000 km apart. Do this 5 times or so, then just change the oil every 5000 km as normal.
