My alto VXR 2005 has been giving blue fumes and drastically reducing oil levels for quite some time now. I was thinking of overhauling the engine. My question is, does over hauling really work? It just seems that once I have a problem in this car and I get it fixed, it comes back again after some time. Secondly, are engine parts readily available in the market for this model. Lastly, what would be the worst-case scenario if I don't get the engine over-hauled? Maybe someone who has gone through a similar experience can answer my queries?
