Exesive oil consumption cylinders or guides?

MAZDA 323F 1.6 16V Doch It is aimed, rod pistons stand the lid and changed valve seals the car consumes 1LT in 500km and humans much after a deceleration, it never dirty a spark plug

Hello Alberto49,
it is possible that it is some of the two causes you mention, it could also be broken rings in the mounted, badly aligned or armed rings upside down, that is to say with the top brand down. Luck.

Hi Alberto49, in addition to what Servilimit tells you, if the shirts are not scratched when riding, I don't know if you will have reviewed the lateral valve slack, if you have not broken any retain when riding it, with the vast vast vast, because it looks like that .. greetings.

It also happened to me, that if the motor equipment is new, the shirt burnished and the adjustment of segments has its filming time and spent some oil until adjusting, apart from this, I suppose that the tolerance of diameters between piston-cylinder-segments are "of the same family" that is said.

Thank you. After walking 10000km and not stop consuming, the cylinders are completely controlled and said that the roller cylinder piston that should be 0.03 was at 0.06 but that it was not like to consume oil because the cylinder is perfect has no stripes and I do not have a conic that should be a problem of kit of piston ring. of valves and the pcv system was armed but the equal sique car, a good power does not sod and not a spark plug but after a restlessness comes out abundant smoke. I am willing to racer it but I do not know whether the lid or again the ccilinders and I do not know how to define what the cause is to find out (25 years ago I repair engines and never happen to me something like that)
