Bad piston rings or valve seals?

[pwuser148913697625]

I have a Suzuki Alto VXR 2007. After fixing my head gasket in mid January due to overheating, I noticed after 2-3 weeks that blue smoke comes from the exhaust only when I accelerate. But when I leave it idle/neutral the car shuts of in 5-15 seconds (even less). During those 5-15 seconds, it doesn't release the smoke, just occurs only when I accelerate.

I googled about this issue and it said "constant blue smoke (even when not hitting the gas pedal) is the piston rings allowing oil to seep in the combustion area. bad valve stems is mostly when hitting the gas pedal allowing oil to get in through the valve where the spring is at."

Do you think it's just the bad valve seals? The car has been driven just 130,000 KM. Can anyone please tell me the cost it will require to change them?

Thanks.

blue smoke on high rpms only is pcv valve in most cases
blue smoke at cold starts is valve seala mostly
although a compression test is best way to find what is wrong with your engine

Yes, there is smoke on high RPM's but not on low RPM's.

Regarding blue smoke at cold starts, it doesn't really release smoke but only when I accelerate, I have to put a little bit of acceleration so that that car doesn't power off.

So you don't think that it's the piston?
