Hello, I am Jose Sebastian. Your automotive expert, It's a pleasure to me to attend your question. Thank you very much for trust in just answer.
Dear customer, are you telling me that you have a high oil pressure in the engine? or that you have a high oil consumption?
thank you for clarifying dear customer, how did this happen? did the engine overheat? or was it after a long journey?
Dear customer, white smoke is a symptom of coolant in the combustion, this must be mixing with the engine oil, this can be a problem in the cylinder head gasket.
dear customer, it is possible that your problem is that the cylinder head gasket has failed, therefore it is not separating the coolant from the oil and is allowing the coolant to pass into the cylinders, which causes them to burn and you can see it in the smoke.
But I am concerned about the noise you are making, because it may mean that you have engine lubrication problems.
I do not think it is wise for you to continue to drive the vehicle in this condition.
Dear customer, the PCV valve is the valve in charge of recirculating the gases produced by the oil, it is OK to check it, but the smoke produced by the engine when this valve is clogged or damaged is very dark blue or grey.
Dear customer, then you may have a PCV valve problem.
But be very careful, because of the colouring of the smoke that you indicate, it is possible that you have a damaged cylinder head gasket.
Dear customer, yes, there could be damage to one of the piston rings, but the smoke should also be dark blue or dark grey in colour.
It is normal that sometimes the smoke is not visible when driving, because it disperses quickly under acceleration.
I hope this info to be helpful, my goal is to give you the best advice i can, I hope to be helpful, if you have any doubt or want to know anything else please do not hesitate to reply back.
Kind regards, Sebastian.
