It sounds like you have a vacuum leak or intake gaskets leaking. Try this. Start the engine and let it reach the idle it want to go to. Get you a can of Brake Clean and spray it around the intake manifold (it on the top center of the engine, you may have to removed a plastic cover) If the engine idle changes up or down then the intake gaskets are leaking hence your vacuum leak. I hope this will help you.

Yes a crappy PVC valve can cause some of your problems but not necessarily all of them, they are cheap, I always replace it to start. The air cleaner housing being full of oil is like how the oil is being consumed. In addition to a PVC valve, there may also be a blow-by hose running into the housing. check to see what other hoses go into the housing & which ones have oil coming from them. I'm not familiar with the "Motor Honey" you mentioned but I rarely add additives to my Engine oil, especially if they are thickeners. The only stuff I recommend is a Quaker state or similar "High Mileage Oil". These semi-synthetic oils have additives to swell old rubber & cork seals in older engines and can help reduce oil consumption & leakage. Again, it may not be a total solution, but it couldn't hurt to drain out all of the existing oil & replace with a high mileage type & also change the filter at the same time. Never mix it with other oils, despite the manufacturer telling you it may be safe to do so.

It likely has worn out or hardened valve seals in the head(s). Oil is leaking into the cylinders through these seals. I'd try a seal softening agent in the oil before doing a valve job. Check your local auto supply for such stuff. A good mechanic can replace the seals without tearing off the heads.

Hello, Are the cooling fan(s) coming on with the truck in park and the engine at idle? If the cooling fan(s) are not working A/C will not cool with truck setting still.

The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke.
Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.
Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.
Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.
