NO NO NO SWEET JESUS NO!!!!!!, valve stem seals Options

[Agent21]

I have a horrible feeling. I can't get the car to stop smoking in start. Lets out a nice white puff everytime..atleast it seems damn white also could be wishful thinking. Car takes a while to get to the power. I mean it has to be up to full temp to get decent power. I am fearing valve stem seals fearing them like an STD. Car has now 158,000 coolant seems to be not leaking. Changed the oil very recently and will be keeping an eye on it. Any suggestions? Note this is on the 6th gen not the 4th.

White smoke typically indicates burning coolant, a sign of head gasket failure.

but at start up of after idle for a little. its simple valve seals!

It is right after start up then stops one big puff

Most likely your head gasket. When you shut the car off, the pressure in the cooling system pushes a small amount of water into your combustion chamber. You start the car up, and poof, it burns off. The coolant can't really leak in while it's running, that's why it only happens at startup.

That is, if it is white smoke. If it's blue, then it's the valve stem seals most likely.

I had this issue right after my swap, just a little bit of white smoke poofed out the back on startup. my warentee in hand took it to the mechanic and had them replace the valve guides, seals and gasket, allong with fully machining he head all free of charge. witch solved the problem
