Question about 2006 Toyota Tacoma PreRunner
I have about 90k miles i switched to synthetic at about 60k and i noticed at around 84k i was missing 2qt from my truck i do see smoke from the tailpipe but i usually think its because of the cold and it does smoke sometimes when i start it up what could it be? No check engine light is on, fuel mileage has dropped significantly, oil is pitch black. my current status of my oil it needs another qt (already added another) and 1k left before i change my oil i usually change it every 5k miles. Help i dont want my truck to die i worked really hard for it and i hate to see it die.
You waited too long. Although I do find it surprising for a Quality Toyota, the switch should have been done BEFORE 25k. Unfortunately the tolerances have opened up too much and you are losing oil about 4 different ways. If you are getting better performance or lower operating temps w/heavy loads and don't mind adding oil stick with it. It is also close to time for a new timing belt. If you change it, have them look at the valves (how they are seating) and the valve guide seals. A compression test would help, and most FLAPS (Friendly or F'ng Local Auto Parts Store) usually will loan you the tester. Your results should be within 10-15% of factory specs, but I suspect you'll find 1 cylinder about 25%+ out of spec. This is a test you CAN do, and find specs online.

Check for fuel pressure when starting. Fuel pumps have a check valve in them that keep fuel in the rail at the injectors. If the check valve fails, the pump has to pump fuel all of the way up to the engine. Same thing with hot no-restarts. Fuel pump.

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.
