Boost leaks from these locations?

[-DSM2NR-]

I added a some sea foam to clean my engine a little bit. As the sea foam was making it's way through the engine white smoke started coming from the valve cover and the exhaust manifold.
Are these places where boost leaks can occur or are they just simple exhaust leaks (the exhaust manifold)?

You will never see a boost leak from your exhaust manifold.

^^^ Agreed, look into replacing your gaskets.

Blow by, this is why it's important to keep your pcv and breather properly routed, all that smoke you see represents fuel mixture during normal operation which will end up settling in your oil if the pcv and breather is just vented to the atmosphere, no vacuum = no ventilation.

exhaust manifold

This is simply exhaust leaks, nothing to do with boost leaks.

wouldn't and exhaust leak slow spooling? pre o2 leaks are bad for the sensor also I thought.

Obviously, perhaps I should've typed "boost leak" instead of just "boost" at the end of my last post.

I've had another question. My injectors tick from time to time. No, it's not lifter tick. I've heard that worn injector o rings might cause a leak. Might this be the case?

No. The top injector "o-ring" seals fuel, not air. The bottom insulators can cause a boost leak but will not leak into the crankcase. In any case, you're not looking for boost leaks because you were under vacuum while running seafoam, not under boost, reason why I ruled out everything else that can leak into the crankcase except for rings (blow by).

ok, thanks
