LB7: Balance rate question

[Dave L Weaver]

Just put new 60 over injectors in and still showing crazy high balance rates on #1 and #2. Is there anything else that would make high balance rates besides a bad injector??? Does not haze at a idle but around 2k rpm it smokes a little blue. Could it be cam or crank sensor ?

Have you checked compression?

 

[Dave L Weaver]

No i have not?

 

[pizza pig]

any blow by? pull the oil fill cap off with it running. Copper washers sealed? Injector cups sealed?

 

[clrussell]

Id check compression..

I guess ill be the guy who asks who did the injectors?

 

[JR WEAVER]

They came from exergy performance. There is no blow by. It would be smoking more if a injector cup was leakin????

If a cup was leaking, coolant would be pressurized. Smoke would be white not blue.

Time for a compression test.

Well sounds like I might have to do a compression test. How would bad compression mess with balance rates?

With lower compression In a cylinder, the more fuel it needs at idle to per say keep the engine balanced. Low compression will mess with injector balance rates pretty good

Ok thanks for the info guys. Will have to do more testing.
