I’ve had vehicles come in with white smoke to me it might be vapor that’s due to water going thru the pistons.

I have had the same prob in my 1996 Lumina. Thought it was rings or valves. Check out your trans vacuum modulator to see if the gasket in it is bad. If so, then it is sucking trans fluid through the vacumm hose back into the intake manifold and burns it in the chamber. Mimics a valve or ring prob. Also check the PCV hose and connections. It could look fine, but it does not take much for a bad hose/connection to foul the PCV function. It will blow smoke out the tailpipe too.

While my tail pipe blows out white smoke

Whatever you do, do NOT continue driving it this way until it is fixed. Hydraulic lockup can bend a piston rod ot even detonate the engne.
I think it got so hot at one point that it blew a head gasket.
Have a qualified mechanic perform a cooling system Pressure check.
If it holds pressure, which I doubt, it may be antifreeze running into your cylinders from he intake manifold. But the pressure test should tell you which head gasket it is, but have BOTH replaced, since they both underwent the stress.AND while replacing those gaskets, a new intake gasket will be installed too, as a matter of course. The price is about the same, since they have the top of the engine apart anyway. Just for information: White "smoke" is vaporized coolant or water being pushed out the tailpipe from the engine. Blue "Smoke" is oil, and Black "smoke" is soot- too much unburned fuel.

Large amounts of white smoke, often sweet smelling, indicates coolant in combustion chamber. Usually warped or cracked head.

White smoke from exhaust too much

If it is steam that means water is getting into a cylinder. Generally this is a blown gasket. One way to test is remove each plug one at a time and turn the engine over. Water coming out of a spark plug hole will confirm. Could be other problems. I had a blown head gasket once and would leave a cloud of steam at a stop light. Unfortunately the car won't run too long and the cylinder would fill with water and stop. Then it was a tow to a garage for repair.

White smoke from tailpipe, running poorly.

Blown head gasket for sure if its a petrol engine.

If its diesel then its overfuelling.

That white cloud is caused by a blown head gasket, the knocking noise could be, a rod bearing, thrust bearing, somewhere in the valve train. Replace the head gasket and see if it still knocks, and change the oil and filter too. If it still knocks, than you have bigger problems.
