I need some serious suggestions.
I HAVE A 1986 CORROLLA WITH A 2C DIESEL ENGINE IN IT. A FEW WEEKS AGO, I DID ALL OF THE HEAD WORK ON THE ENGINE, INCLUDING EVERYTHING, BUT THE ENGINE IS STILL BLOWING AND REDUCING OIL FREQUENTLY THROUGH THE PIPE OVER THE HEAD, AND THE MECHANIC IS SAYING THE BLOW IS BECAUSE OF PISTONS AND CRINGS UNDERNEATH THE HEAD. PLEASE INFORM ME IF IT IS FEASIBLE TO PROCEED WITH THE ENGINE.

sounds like a case of general overhaul
how can just a headwork fix it

Plz make sure its PCV valve is open and not blocked.
Then check the compression test.
If the compression of all 4 cylinders is fine, then you don’t need to overhaul the engine or anything similar.
But if the compression values of all 4-cylinders are not OK, then it means the rings are weaker and either it needs complete overhaul or replacement.

there's play in the cylinders
