These will help.
Thanks.

are you draining all the oil or just whats in the gearbox?
nobody can say how much you will need to the last drop really
but you will need at least 6 pints then check the dip stick and runing the motor,,, keep filling till its a full box

Is it coming from the driver side, passenger side, front or rear of the engine? It could be a cam or crank seal if it is coming from the passenger side behind the plastic timing cover.

that is normal fuel tank pressure, about 4 PSI, have you ever replaced the spark plug wires?

change fuel filter, add a can of SEAFOAM to tank of PREMIUM this 1 time. you have EGS(ethanol gas syndrome), and sounds like its very bad in your car. The corn by-product in your fuel creates a goop and puts lots of water in every part of your systems. you egr valve and your engine valves are heavily carbonized right now and need help.<p>
Your injector spray is next to nothing. Your ECM controls the amount of fuel spray to your engine, and it the injectors are partially clogged, it tells the injectors to spray more to keep up;thus causing flooding.<p>
I know it's alot to take in; but trust me, it's not fatal.<p>
You may have to change your fuel filter again at 500 miles to get the last of it out, so if you do, you do.<p>
Add SF every 3-5000 miles after this, and it will keep everything clean,unclogged, and carbon clean. GOOD LUCK

Sounds pretty normal to me.

Check the radiator cap for white sludge, if there is some then check the oil dipstick for the same, if on both then 95% sure it is head gasket blown.
If there is a little on the rad cap and none on the dip stick then may be low on oil.

The low-pressure side recharge valve was changed with the conversion to 134 so it is nearly impossible to use the wrong stuff.

I found this discussion that indicates your car requires R-12 if it has not been converted:
