Chevrolet Epica Motor 6 cylinders

Good I am looking for the Chevrolet Epica workshop manual I have several problems with my car and many mechanics tell me that the car does not work and I would like to repair my car

It is difficult to find those manuals on the Internet at no cost but you want if you tell us the problems we can help you.

The car is bought at a Mrs., the main problem was first the oxygen sensor bank one, then the box with the valve body, the valve body was changed and the catalyst was removed to remove the problem, work like this one year without problem and performing maintenance up to date, but now it tells me the mechanic that the engine has to do for the blue smoke that the votes, but the compression is 3 months ago, but the compression 185, the bench sensor is giving problems, the valve lid is Happy Humid, and as if it were little the oil filter came out and I fixed and I miss oil 4 liters I changed the filter and the base of the filter and it is removed but save has a vote of oil for the steope and by the valve body, when accelerating hits but it does not seem box that is why I am looking for the manual

The last part is not very clear, but if the vehicle is bursting by oil, then if you can have the problem of rings now the blue smoke is due to two things or rings or vents of valves. To my pairser the best is an engine adjustment like this, you also have a metal noise as if suddenly and it is the engine we will safe with the adjustment.

Ok thanks for the aid, that's why I'm looking for the manual, anyway, thank you friend
