Well...the 911 is at Matt's. It's pretty smoky and Matt's pretty concerned.
We did a leak down (between 3 and 6) and it seems OK for the mileage.
But we can hear air rushing out of somewhere we cannot yet locate.
We hooked up the smoke machine and smoke is coming out of
some weird places - like out of the #1 spark plug hole in the cover,
while the plug is inserted. Also out of some space between #1 and #2,
seemingly through the alloy. Now, we all know this is impossible.
We hooked up the computer and started it. Between billows of blue
smoke, we see a few cylinders go goofy on Kv's and then after
a few minutes start to normalize as the smoke reduces.
The engine is really lean - like 0.532 - even with the sensors
all bypassed. We did verify the computer seems to be working.
So, it is still a mystery, but something or some things are going on.
Seems to be a multiple choice answer so far:
1. mixture is lean - need to fix
2. something is leaking oil and burning - would be nice to know what
it is to be able to determine what the scope of the repair is...
Hmmmm....
