Mk7 transit copper washers

[Kyle101]

Hi guys, posted on here before regarding one of my company vans

We also have a mk7 transit 2.2 and the injector bolt had snapped causing the injectors to bounce up and down, unfortunately one of our employees continued to drive it leaving the copper washers welded to the injectors Which we have been told has made no damage to the engine, fortunately we were given a set from a working van with that started great no smoke but our mechanic has installed the injectors not realising there must of been some remain of washer left in the bore of one injector so due to injector not being sat flush its chuffing oil so basically im asking whether

If one of injector seals arnt sitting flush can this be letting oil weep into piston causing abit of smoke in the morning/ lumpy idle untill ive give it a few revs ?

Also

Can imjectors being coded but not pilot learned cause smoke?

Any help would be really appreciated, thanks

The seats in the head need recut, then a full set of new copper washers, they’re not really meant to be reused.

Uncoded injectors can cause rough idle, slight loss of power, diesel clatter under load etc etc

Thanks for that mate, injectors are coded just not pilot learned

So if the washer iin the 1 injector isnt fitted right it can be letting oil seep through hence why ive lost some oil and it smokes for a second in the morning?
