Pull the vacuum hose off the fuel pressure regulator on the fuel rail on the engine. If that is wet inside, replace the regulator.

White smoke from the exhaust is a sign of burning coolant, but that is not related to gas in the oil. The burning coolant is caused by a leaking cylinder head gasket. The clue is the level will be going down in the coolant reservoir. I cannot think of how the two symptoms could be related.

When I took the radiator cap off while it was running earlier, the coolant in the radiator was jumping up and down. It didn't matter how much water I put back in, it would still go down.

Have your mechanic perform a chemical test at the radiator. That will identify if a head gasket is leaking. You can also add a small bottle of dark purple dye to the coolant, then check later with a black light. The dye will show up as a bright yellow stain. If a head gasket is leaking, you'll find the dye inside the tail pipe.

I bought a head gasket, valve cover gasket, and fuel regulator. I'm going to change the fuel regulator along with putting new oil in it today to see if it stop the gas going in the block. Then when I get time off I will change the gaskets.

It was the fuel regulator. No more white smoke. Going to put the gaskets away for another day. Still have a miss in it so doing a compression test on it tomorrow to see what cylinder it is

Dandy. Cylinder head gaskets are a real big job that includes special tools, procedures, and should involve an engine machine shop. Don't attempt those unless you really need to.

I've been doing mechanic work for a long time. There's not something I haven't done with a vehicle so it shouldn't be a problem to complete it. But I do appreciate your help with figuring my problem out. Thanks man

My previous comment was based on you listed, "Little knowledge". Head gaskets aren't a big deal when you know what you're doing.
