And if soemthing needed to be replace i was trying to put better internals, bearing etc etc, lower wise, but i dont no if i would have to have the shop tear it down completely just to replace something like that, or if i would have to replace a whole set not just one peice with aftermarket parts that can hold more power, thank you guys for ur response im totally lost and miss my z );

In my experience if you are going to choose a shop to bring your vehicle to they need to have experience or specialize in the VQ37HR engine as it is a complexed engine that requires knowledge. Your missing motor oil or coolant went somewhere it would be a good idea to get a leak down test and compression test to find out the health of your engine or begin tear down and replace your engine it is your choice and your diagnosis should determine this. In my experience I have used Royal Purple motor oil in a 4.6L 2V V8 engine and at 99k miles it had three internal rod bearings fail. After doing my oil research I found that Royal Purple is a snake oil and from the oil analysis tests I read the four ball bearing test and metal shearing test was high on wear which led me to believe the lubrication properties in Royal Purple motor is thin and does not protect your engine well at all comparing to other motor oil brands on the market. My decision was to never use Royal Purple motor oil in any of my engines again as I found there are other motor oil brands that will protect your internal engine parts a lot better. Also not changing your motor oil and filter on time can be detrimental to your engine. If you search there are reputable engine builders out there. In my experience MA Motorsports and Import Part Pros are excellent choices as they both have experience with the VQ37HR engine.
