update on the engine problem.we done a compression test and its well within limits.
my cylinders were between 8-9 bar and we checked on autodata and they seem alright.
there was an oil leak between the headgasket and oil pump cause the oil pump was put on after the head which means the headgasket wasnt compressed properly.so it could be possible that it just needs a headgasket
which means an even cheaper bargain
