Whops yes thats gas leaking, none of that. I mean to say dark-bluish deff the oil kind.

4psi is low at hwy speed, but normal at idle.

blue (ish) smoke is oil.

the hose is there to link (air vapor wise) the block to the top end. leave it alone.

the pcv system has no valve. the 2 hoses come off the valve covers and "Y" into the throttlebody. see the FAQs section for proceedures to clean that out so it works right.

Oil pressure is 4 kg/cm^2 which translates to 57 PSI.
So I guess I will just have to wait to do my compression test and see where I am going from there.

A compression test may be pretty good, and you could still have some bad oil rings on a piston or 2. That can let it smoke, and still run good, until a spark plug fouls. Pull all the plugs and check them for oil contamination.

In the end I think it is actually a leaking injector that produces the smell. I bought a new compression tester and everything came out within specs. One plug looks washed by gas and I can actually hear one injector leaking. My fuel pump does not stop running so I am positive now that one injector is leaking. I supose a leaking injector would create a wierd smell.

Yes it will (smell). And....after you repair it (very soon), better change the motor oil, as it will be full of fuel.

At the shop, we like to use new injector when the customer isn't a tight wad, because rebuilts can have problems, now or sooner than a new one.
