I seem to be boiling coolant out from under the water inlet on the intake manifold. This is a brand new problem that just appeared, Any assistance would be greatly appreciated. Still need a little help with this though

install fuel management first and then bigger injectors... not the other way around.

I bet your oil is contaminated with fuel now, good job.Get a proper tune, what the heck are you trying to do?

I haven't driven her much at all yet, just down the street to make sure everything was hooked up correctly,

I have been running her a little stationary to work out any bugs that may arise. I am hooking the SAFC-II up this evening, as well as the wideband

The SR20 Injectors we bad, I put the Stockers back in and she worked like a charm.

I still have a good deal of smoke at idle, but under throttle there is barely any.

I am thinking that maybe the seals on the turbo I have are bad. or that the restrictor I have is not small enough.Any input there?

Oil can smoke a white color. I'm not entirely sure when it does this, but both times I had a turbo seal failure, I got white smoke. My speculation is that it occurs in cases where the oil is heated to the point of evaporation but not burned. I'm fairly certain oil only leaked passed the tubrine housing seals as I found no indication that there was any oil being forced through the intake.

The reason it only happens when idling, is because of the pressure differential across the seal. At idle, there is going to be very little pressure in the exhaust. The higher pressure in the center-housing will allow oil to move past the seal if it is partially sealing. Under boost, the exhaust manifold will be at higher pressures and will either provide an equal force against the oil pressure, be higher than the oil pressure or only allow a very small amount of oil to leak passed the seals. Depends on how bad the seals are and what kind of pressures are seen on both sides of it.

In my case, I was able to prevent it from smoking by leaving the A/C on. The higher RPM's actually prevented it for me. Each person's situation will vary depending on how bad the seal failure might be, the oil and exhaust flow rates. Assuming it is indeed a turbo seal failure, fixing that would be the only sure solution.

what makes you think the injectors were bad?

I should have been more precise, 1 of them was bad, I pulled them out and at some point when I was putting the IM back together one of the people I had helping me, apparently dropped it on the ground and actually punched a larger hole in the nozzle, so the fuel wasn't exactly spraying as much as it was just draining into the motor.
