Milky engine oil and white smoke at start up on 3.5L v6 petrol (G6DC) Grand Carnival
I'm new here and hoping to get some help.
Just bought a used 2013 Grand Carnival / Sedona with 3.5L v6 petrol engine with 107,000 kms.
Engine code is G6DC.
Really dissapointed as there is thick white smoke at start up for about 5 secs.
Discovered coolant on oil cap. There is milky goo on cap and in engine.
Coolant reservoir is low. Haven't driven much but not overheating yet.
Mechanic replaced PCV valve which fixed blue smoke problem but says need to swap engine out which will cost around $7k Aud for a wrecker engine. Ouch!
I've taken car back as don't trust his recommendation as he hasn't done tests to find out cause of coolant in engine oil.
Has anyone come across this problem and do you think needs new engine?
Any help is much appreciated.
