EXPERTS! premature Camshaft breakage issues!

I just recently got my daewoo's eingine overhauled, i got the head faced and got the blocked sleaved so now its running on standard pistons. Since this time the head was faced for the third time the mechanic was of the view that two gaskets should be used so that it may compensate for the matteral faced off, while me and my father were totally against his concept, but still we let him do it cause else he was not taking any responsiblity if anything goes wrong with the engine ( #&*%)(@* mechanics!! :@ )

anyways the engine was done with and during the running period after about 300 kilometers and can shaft broke while driving at a speed of 20km/hr

the mechanic was called, and he just simply said that this is a daewoo and this usually happens with it

this too was something that me n my father simply couldnt digest because EVERYTHING happens for a reason! well a kabli camshaft with its own cage and tepits was bought from bilal jung and fitted.

The car was working fine till yesterday that this camshaft broke too after running only for almost 1200 kms.

Both the camshaft broke from between the the valves of cylinder number TWO.

im attaching the pictures of both the camshafts!

the mechanic also blamed that the oil pump was not changed in this over haul, this could also caused both the breakages, but the oil pump was checked by a mechinist and it was only not changed becasue it was working properly!

Your mechanic is covering the same aspect i am talking about

A full head swap will cure the problem. Actually the cam housing (cage) has unevenness among each other i.e. all bearings are not of same size.
