I’ve been fighting an LLY for 3 weeks now. The only saving grace here is that the truck belongs to a tech so there is no retail customer breathing down our necks.
Originally, the truck came in with a fuel knock and a balance rate of +2.42 on the #2 cylinder, he wanted to just change #2, I warned him the rate on #5 would probably change as its compensating. Did so anyway and sure enough #5 went bad.
So he decided to do the other 7. After that, it ran like a bag of shit with balance rates of:
1 -2.74
2 +.094
3 –4.70
4 +1.47
5 +.16
6 +1.33
7 +1.48
8 –.088
So at this point, I’m up against a wall and I give him 4 more to change the odd # bank, well, no better now.
1 +6.73
2 –2.94
3 +1.03
4 +1.21
5 +1.59
6 –1.30
7 +1.55
8 +2.16
So now what do I do?
I wouldn’t point the finger at the injectors if it wasn’t for the fact that in the last month I have had 3 dead LB7 injectors “brand new outta the box”...completely dead, +15 rates, no ohms, zero zip nada from these guys.
To top it all off, I've got fuel in the oil, which I've never seen on an LLY. My research tells me that a CP3 seal leak can cause that, but my fear is that one injector is washing down a cylinder.
Anyone have any insight on this? I'm thinking swap out all 8 with a different supplier.
