Have had oil issues since day 1. Catch can would overflow in no time. Initially blamed it on oil pooling in the heads.

 

Had the ID1000 injectors flow tested...looks like they didn't appreciate being cleaned. The automated test is a gradual ramp up.




So static(max) flow rates for the ID1000s were:

Initial/After 2 cleaning cycles

1. 864/888cc/min
2. 852/876cc/min
3. 864/888cc/min
4. 852/888cc/min
5. 852/876cc/min
6. 876/900cc/min
7. 852/888cc/min
8. 864/864cc/min

With 2 and 6 being erratic. Not sure why #3 was clean as a whistle(see pics) compared to all the rest. Wiring checks out good to all injectors.

What I had noticed was that bank 2 would tend to go way lean on a heat-soaked idle. Cold testing doesn't tell me how the injectors behave at higher temps.

 

I have zero experience with turbo LS motors, but cant oil in the chamber lead to some serious detonation that could be feeding on itself in this situation?

 

^ certainly could. Same physics applies in all engines. Oil in the chamber is bad.

Sounds like there are a lot of issues going on between engine assembly and fuel system. Oil problems from day screams machining/assembly problem. I am with George and think you should do a full tear down to see whats going on.

Throw you blower setup on a 4.8 and make 1200hp with twin roots superchargers
....it should last until you finish rebuilding the nice engine anyway!

 

Or until first WOT...whichever comes first.

Red hot carbon and loose chunks of carbon flying around aren't good!

Definitely seems like it has always been pressurizing the crankcase.

 

How is that intake manifold setup?

 

All vac ports at blower inlets.



Some modifications since this original fabrication pic from Rick(Trick Turbo)....

 

If be curious if some of your issues is directly related to that manifold

 

Lower should basically function like a TVS kit. IC core into an open box with 8 ports. This is the current lower.
