I found this website while trying to find out for myself. I have not tried it myself, nor do I know where to get the special tools, but it's a step in the right direction. http://www.darklair.com/monte/howto/howto.valve_seals.html
No, exhaust does not have enough oxygen in it for the engine to run.
Intake manifold gasket may be leaking - check for loose bolts or replace fasket.
Cold air intake or exhaust would be the simplest and cheapest.

Could be a diesel? If not then replace your oxygen sensor on your exhaust. A bad oxygen sensor causes the exhaust smoke to be dark in color.
2 per cylinder,4 intake and 4 exhaust ,they are different.
If you aren't hearing a lot of exhaust noise and you're just getting smoke, you have either an oil leak or antifreeze leak that is getting on the exhaust manifold. If you're getting oil on the manifold you have a fire hazard and should take care of the problem immediately. If you hear exhaust gas leaking around the manifold you need to replace the gasket or possibly the manifold is cracked and you need to replace the manifold.
any 225 sl6 from 1960-87 will fit car or truck as will intake .I have one no cracks call me 250-751-1652
It could just be condensation which forms in the exhaust system outside of the engine, or you could be leaking coolant into your engine (typically via the head or intake manifold gasket).
Intake manifold leaks will cause the engine to idle rough and get poor fuel economy. An exhaust manifold will have no symptoms other than the sound of the leak.
You will need to replace the intake gaskets to fix your problem. The HEAD GASKETS will not be your problem.
In a diesel and petrol vehicle the turbo turbine is spun via exhaust gases exiting from combustion from the engine. it takes a short amount of time for a turbo to produce boost because of the effect of waiting for combustion and exhaust gases to spin the exhaust turbine. but saying this the turbocharger creates no load on the engine, not like a supercharger which is belt driven off the crankshaft which means you have to give power to make power. two sides to the turbocharger featuring intake and exhaust. while exhaust gases spin the exhaust turbine, which is connected to the intake turbine it spins the intake side creating a vaccuum and compression of the intake air. so with more revs and more exhaust gas created it also increases boost or air intake at the same time.
